Windows 8; high cpu usage on explorer (~50%)

I just restore my laptop, and now i noticed that my usage is above 50% and the major usage is because of explorer.exe which showed 49-53% in Task Manager.
Is that normal? Is there any solution to lower down the usage for explorer?

Hi,
For high cpu usage issue, I usually use Process Explorer to troubleshoot, here is a link for you to download:
Process Explorer v15.40
http://technet.microsoft.com/en-in/sysinternals/bb896653.aspx
It's a simple and small tool, once you installed and open it, locate to explorer.exe, you will find all processes related with explorer running in your system, find the culprit of the high cpu usage.

High cpu usage when moving application windows

Hello all,
I have two machines with arch installed:
- an eeepc 701 surf/intel gpu(xorg driver) with xfce
- an amd 3800+ X2/nvidia 8860 gt(proprietary driver) with kdemod3(also checked with xfce4)/arch amd64 installed.
I noticed that when i move a window of an application(for example konsole, etc..) too fast i get high cpu usage(30-40 %), when checking with htop.
Is it normal that the X server uses the cpu so much when moving a window??
EDIT: up to now i tested it in a friends windows machine, and it happens exactly the same, so i guess is normal. It seems i need to be informed better about how X works :-)

today i switced back my desktop system to debian unstable and tried to see what the difference is concerning this problem.
I found out that in kde3 the solution to the "problem" is debians kde default configuration about window behaviour.
Especially the one mentioned below :
In debian this is not ticked and this has as a result zero cpu usage when windows are moved.

CSA 4.5.1(657) high cpu usage on windows 2003 sp1

Hi,
We have experiancing high cpu usage on windows 2003 sp1, when somebody logs in remotely. The server has 1gb of ram and the cpu is 2ghz. The Cisco Trust Agent (1.0.55) is installed also.
When somebody logs in remotely the process okclient goes to 100% cpu and eats all the available RAM and the machine starts to swap, the pagefile has grown to 1gb. This is not all the time though, only in some cases like this one.
Could this be due to some specigic policies associated with this machine be the cause of such behaviour?

Hi Rossen,
It could be due to some @remote rule but first some questions:
What is the server function?
What groups is it in?
Does it have 2 enabled NICS?
Is it sharing anything other than admin shares?
Is it a member of AD\Domain or standalone?
Why is the CTA installed?
Why is your page file dynamic and not static and why is it only 1GB (should be 1.5x physical RAM)? Growing a page file is a slow and painful process.
You can try some things right away:
Either remove if from the groups that have @remote rules or put the server in a group with no rules\policies at all. That will tell you if it's the agent or the rules causing the problem.
Good luck!

PKR crashing - high CPU usage (windows XP, bootcamp, Macbook Pro 2.5GHz)

The PKR (3D online poker) client is crashing - often half way through a game, frustratingly. I'm running Windows XP via Bootcamp and have updated to the latest Apple Bootcamp drivers. I notice very high CPU usage (consistently maxing out a core) at all times when running PKR. Anyone else having trouble with this software?

I've also been getting Kernel panics in OS X, so I took my MBP to the Apple Store in Regent St, London. They tested it and found a problem with the memory controller. After a logic board replacement the laptop is performing very well - no crashes so far in Windows or OS X. Fingers crossed.

Mixer window can cause high CPU usage, crashes

This is probably one of the weirdest bugs I've seen for a while. Here are the steps that I reproduce it for me, maybe someone will want to try this out and see if they get the same.
1) Open an Empty Project template.
2) Create 16 instrument tracks when it gives you the dialog. (even 1 will be enough, but the effect is clearer the more tracks you create)
3) Open the mixer. Either in a window or in the pane.
4) Now create a "multi-timbral" instrument track with the plus button (use the checkbox there).
5) Select the 16th track, and now select one of the arrange tracks of the multi-timbral instrument.
6) Open up Activity Monitor from your Utilities folder in Finder and see how much Logic is taking up CPU. It should be significantly higher than the idle state. On my MBP it'll be around 80%.
This is not a problem in itself, because when reproducing it like this the high CPU usage goes away when you select another track and won't return if you select the multi-timbral instrument again.
However, I have sessions where this will continue happening with a multi-timbral instrument all the time. Not only that, I've had Logic crash when this starts happening. And this whole thing will slow down the UI considerably when it's active.
The workaround that seems to work for me is simply not keeping the mixer window/pane open.

This is one of the issue which has already been raised to Microsoft and hopefully a public build will be available soon in next cumulative update pack .
There are variety of reason for this starting for password mismatch or password not given , SFTP adapter unable to connect and so on .
There is good post here in below link for this issue
http://thoughtsofmarcus.blogspot.co.uk/2013/06/leaving-password-blank-in-biztalk-2013.html
Another greate artcicle is by Nino which states these issues .SFTP adapter is protocol sensitive and some configuration by server side, can cause a lot of crazy situations

High CPU usage while buffering a video

I have a high CPU usage (over 40%) while only buffering this video.
IE10pre1
Firefox Nightly 20121229, protected mode enabled
Firefox Nightly 20121229, protected mode disabled
Opera Next
Chrome Canary
a) open this url: http://www.wimp.com/marsearth/
b) pause the video if it starts automatically
c) use task manager or process explorer to view the cpu/gpu usage
reproducible: mostly
Windows 7 SP1
Flash Player 11.6.602.108 / HWA enabled
TestPC: Gigabyte GA-K8NS Pro; AMD Athlon 64 Venice 3200+; 2x 1GB MDT DDR-400-CL2; Club3D HD4670 AGP; Samsung HD103SJ, SyncMaster 204BM

While we're aware of the issue, there's not much we can do about it. The modern security realities facing web browsers have made sandboxing a necessity.
There's a good explanation of what's happening here: http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html
Long story short, each video packet has to be passed from the browser to a medium-integrity broker process, then to the low-integrity flash player process for rendering. If an attacker manages to hijack the Flash Player thread, the process is low-integrity, which prevents the attacker from doing much with it. While it's not an absolute guarantee (nothing in security is), it raises the bar significantly for attackers.
The downside is that all of that extra message-passing consumes CPU cycles, especially if you're trying to fill an exceptionally large buffer as fast as possible. There's not a lot of opportunity to optimize this.
If you're fine with the risk, you can manually disable ProtectedMode on your machine. If you're only dealing with trusted sites, and you're not doing anything critical with the machine (work, banking, etc), then it's probably not a huge deal.
Ultimately, ProtectedMode is like a vaccine -- it's a herd-immunity thing. If the majority of people run it, exploits targeting machines without it are inconsistent and probably not worth pursuing when you look at the effort involved in developing an end-to-end exploit. If a large number of people disable it, it becomes economically attractive for people building botnets, and you'll have a problem if you're not using it.
To disable Protected Mode, add the following line to your mms.cfg file located in:
Windows 32bit: C:\windows\system32\macromed\flash
Windows 64bit: C:\windows\syswow64\macromed\flash
ProtectedMode=0
If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)
Depending on your operating system, you might need to first save the mms.cfg file to a writable location (such as your documents or desktop folder) and then copy the file into the destination folder using Windows Explorer.
To re-enable Protected Mode, simply remove the line from the mms.cfg file.

Excessively High CPU usage on my Equium M70

HI,
Recently in the last month my CPU usage as been hitting 100% when Im not running any taxing software (just internet explorer and windows media player).
This is slowing down loading times and the area near the fan is pretty hot.
I have an Equium M70-337, with a 1.7 centrino processor, and now 2 gigs of RAM (formerly 512 megabytes). I upgraded the ram in December and had no problem like this, now it's just started happening recently, I haven't installed anything that would do it, there are no unnecessary programs running and this was after I restored my comp to factory settings with the startup disc (about a month after) so it seems to have come from nowhere. On the task manager list it shows my web browser and media player using up the majority of CPU but I could have sworn that they didn't use up this much before.
I don't know if the RAM would have been a factor but it was the correct ram for it and windows acknowledged to 2 gigs.
Why would this have happened suddenly, any ideas guys?

Hi
I have the same notebook model and at the moment I do not have such problems. To be honest I have made clean OS installation 3 months ago and after Microsoft update installation I have noticed that notebook does not run like before. Just for example: if I use IE7 intensively with several different tabs in task manager I can see that IE need over 300.000 k of memory and somehow blocks. After closing IE and ending the IE process sin task manager I can work normally again.
I really do not know how is your OS configured but in task manager you should see which running process is responsible for high CPU usage. Maybe some antivir application? Sorry but on this way it is really not easy to sayt why this happen. Play little bit with running processes.

High cpu usage when the system is idle

I do have a high cpu usage problem when the system is idle. I bought the laptop (lenovo x230 tablet) with windows 7 installed in it. Then upgraded to windows 8. But ever since I have problems with high cpu usage by the system even when the computer is idle.
Only the system by itself uses around 30% of the cpu all the time. I ran xperf, and here is the result of it:
http://sdrv.ms/Kj6CFN
I appreciate any help you can provide.
Thanks,

Hi,
I'm sorry for that the log you provide can't be opened on my computer. While according to your description, it should had a special process that consume CPU usage when system idle Iguess, isn't it?
You can use
Process Explorer to monitor the process activity, may be we can find the reason of this problem.
Note: We can use Process Explorer to check the Stack of every process then analyize the problem in deep.
To gave a better insight about this problem, you can take a ScreenShot for this problem and provide the picture here.

High CPU Usage on Satellite C655S5132

High CPU usage On Satellite C655S5132 when running Window Explorer Internet and other programs. CPU use is so high it freezes computer. I have went back to original factory setting, ran virus programs nothing helps and flash player keep crashing. Please help.
Desperate

Has this been something that just recently started happening, or have you had this issue for a while? Have you installed any new programs recently?
You may want to download Glary Utilities, which is a free software(they will ask you if you want to go Pro, just say no, the free version works very well). There is a module for startup manager. You can go in and disable stuff that starts with the computer. I would advise unchecking adobe, java, quicktime, printers, etc. Anything that doesn't REALLY need to start with the computer. The nice thing with Glary is that you can restart the computer, and if you find that you need one of the programs to start with windows, you can go back in and enable it again.
The Celeron 925 processor in your computer is a decent entry level processor, but if there are too many programs running in the background, it can bog down quick. I would also recommend downloading and running Malwarebytes Anti-malware, to be sure that there is nothing malicous running in the background.

High CPU usage by Service Host & Services and Controller app

Hi All,
My CPU is running at a consistent 98-99% within moments after booting my machine. I have uploaded a ~30s ETL capture here:
hxxps://www.dropbox.com/s/xznhkdyo5p2p7rn/highcpu.07-03-2014.10-46-16.zip
I've been digging around, but I can't seem to find what the cause of this high CPU usage is. It appears to be affecting the explorer service as well as Chrome. CPU usage does NOT go down if I kill all chrome processes however.
Any insight would be wonderful.

Hi,
According to your screenshot, it seems this is not related a particular service, it just like a memory leak issue.
Can you check the event viewer to see if there is some error record?
Or you can check if this issue happens in Clean Boot mode, this would eliminate software conflict:

Config Manager Agent - after Hardware Inventory High CPU Usage with WMIPRSVE and very fast empty Battery

Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...
try running those queries from wbemtest manually; and see which one just never finishes.

Having Issues with High CPU Usage with fluxbox & pekwm

Greetings,
I have searched for this issue and it seems that something similar has happened in the past with an old xorg, and it seems that someone is having a similar issue that they can point to kde as being the culrpit. However in my case, this is a fresh install and is not using any kde libs. Please allow me to explain the issue.
The power supply on my main computer finally gave out, and being incredibly poor at the moment I can not yet replace it. So, I pull out an older computer that I had once set up for my kids, but took it away from them when they were abusing it. I always make backup dvds and such monthly so I didn't have to worry about any lose of data, however I desired to keep my larger hard drives from my main computer. After testing to ensure that the hard drives were fine, I did some minor surgery, and did a fresh install of arch linux onto my back up computer. Since I prefer pekwm, I installed pekwm as my wm of choice, and outfitted it quickly with mpd+sonata, firefox, pcmanfm, and tint2. Then I rebooted into my pekwm 'desktop'.
It was running sluggish. Firefox was easily maxing the cpu up and beyond 100% and it felt ten times worse than any heavy DE I used in the past. I checked to make sure I had the right video driver installed. As this computer runs a 64MB nVidia GeForce2 MX with TV out video card, I searched nvidia's page and the arch wiki, noting that the driver needed is nvidia-96xx. Well I had already suspected that during install, and thus had installed such driver. I double checked my xorg.config and it has the right driver listed.
So I checked out some lighter browsers. I tried both Midori and Iron (which is similar to Chrome but without google spyware or whatever). Well both run better than firefox, Midori being the lightest one, but Iron quickly being my favorite. Still, the problem remained. Moving windows caused cpu spikes, opening more than one tab, or more than one program caused cpu spikes and the computer to slow down and sputter, freezing at times.
So I tried out another wm, fluxbos, which is another of my favorites. Seemed somewhat better but only fractionally, which I consider odd because pekwm has always seemed snappier than fluxbox to me in the past. Running lxtask (still mouse dependent, sorry lol), I was able to take note of the following...
FLUXBOX
lxtask 6% CPU usage average
PCManFM 5% CPU Average
Fluxbox 1% to 2% cpu usage
gksu 3% cpu usage
pidgin 3% to 7% cpu usage
firefox up to 62% cpu usage
midori up to 38% cpu usage
iron up to 50% cpu usage
mpd 11% cpu uage
Xorg (with no window movement) 2% cpu usage
Xorg (moving windows around) up to 80% cpu usage
PEKWM
lxtask 6% CPU
pidgin 7% cpu
tint2 1% cpu
pekwm 1% to 5% cpu
pcmanfm 7% cpu
firefox up to 85% cpu
python 1% cpu
midori up to 38% cpu
iron up to 25% cpu (odd...)
Xorg (with no window movement) 1% cpu
Xorg (when moving windows around) up to 80% cpu
Both were using around 118 MB RAm and weren't yet touching swap. As I see it I am thinking xorg or video driver related, yet I already made sure that I had the correct video driver. Here's my Xorg.conf

So what I am wanting help with is finding the solution to the cpu usage so that I can use this computer at least until I can afford a new power supply or whatever. I am open to any good suggestions, though I must state I am not really interested in tiling wm's at the moment. I am just not a true minimalist.
Thanks in advance for any and all help. I understand that there is a lot of info in this post, but it is my hope that with this info the problem can be solved. If there is info I didn't provide that is needed, please let me know.

also check that you have
session.screen0.opaqueMove false
in your .fluxbox/init this will probably help a bit if it is currently true,

High CPU Usage in Word 2013

Hi everyone,
I'm having an issue with Word 2013 and I'm hoping someone can help. Seen as I got fleeced for my TechNet subscription this year (the price given on the invoice doubled when I called up to pay!) I’d very much like to see a speedy fix from the Microsofties
please! :D
Recently, I've found that Word will consistently exhibit high CPU utilisation, ~50% on a dual core second generation Core i5.
This continues, even when I’m not providing any input to or interacting with the Word window and even when the Word window is covered by other windows. Minimising Word causes its CPU usage to drop back down to zero.
The strange thing is that, so far, I’ve only observed this with a single document. I started writing this document at the start of this week and it’s been authored exclusively on Word 2013. In fact I’m the only one who’s editing it and I’ve only used a single
computer (and this one single install of Word 2013) to do so…
There’s nothing particularly unusual about this document, and a different but similar document which uses the same themes and features (in fact the theme for the second document was created from the first one) doesn’t appear to cause the same issues. Both
these documents are stored on SkyDrive, and are being edited directly from there.
Initially I tried the much recommended tweaks of disabling hardware graphics acceleration and sub-pixel positioning, however neither of these has had any effect.
I investigated a bit further using Sysinternals Process Monitor, and found that while Word is using a lot of CPU it’s actually looping very, very quickly polling for the existence of the registry key “HKCU\Software\Microsoft\Avalon.Graphics”.
This key doesn’t exist on my system, and a quick test I conducted where I created it just lead to Word looping polling for more non-existent registry keys.
My system is a HP Folio 13 running Windows 8 Pro x64 with Office 2013 (RTM, not Beta) 32 bit. Both Windows and Office are fully patched, as is everything else on the system.
Thanks in advance for any help anyone can offer.
Chris

Hello again,
After working on my problematic document some more, I believe I’ve found the cause of the issue.
@Microsofties – I think this one is either a bug or a dodgy OOTB template…
I noticed that the high CPU usage only seemed to occur when the document’s footer was displayed. Experimenting with some careful scrolling and zooming to hide footer (without actually using the “hide white-space” option) seemed to confirm this so I investigated
the footer a bit more.
My document was using the standard Word “Facet (Odd Page)” footer template with a couple of fields added to suit my needs, namely “Publish Date” and a page number.
The template seems to be structured such that the content of the footer is inside two nested text boxes (one inside the other). I also noticed previously that this footer template also appears to “jump” up each page and back down again as I scrolled.
So I deleted the footer and its text boxes, and recreated the same content, in the same position (using the standard paragraph alignment tools) by hand without the nested text boxes. This has, so far, fixed the issue!
I also noticed that the CPU usage dropped right down to idle the moment I deleted the nested text boxes.
Altogether, this leads me to conclude that the “Facet (Odd Page)” footer template in Word 2013 is the source of my issue. Specifically, I believe that the use of nested text boxes in this template causes Word’s interactions with the .Net 4.5 WPF to go a
bit nuts, as evidenced by the infinite loop of request for the non-existent “Avalon.Graphics” WPF registry key I mentioned previously.
It would be nice to see some feedback on this one, Microsoft people, if only to know if this is actually a general issue or is specific to my document!
Thanks, Chris

High CPU usage when graphics card is put at work

I have a 13inch Air with 2GB RAM and 256GB with Windows 7 Ultimate 64bit. All possible updates have been installed.
I noticed some tearing when trying to move program windows across the screen so I started checking the CPU usage. I saw that it is spiking to 25-35% when moving a window across the screen.When you drag down a window you can see the different copies of the top bar across the screen. Not smooth at all like on a standard PC windows system. Same issue when scrolling through webpages which spikes the cpu
I also noticed a high cpu usage when playing mkv files 25-30% while on an Atom HTPC i get a lower load playing the same file. The Air should be faster than an atom with a nvidia 9400m when playing video files.
I already tried updating the nvidia files to the latest version on their site by hacking the driver inf but this did not resolve the issue.
Has anyone experienced the same or know what could be causing the beavior?
Many thanks

Maybe my initial post was not clear so let me add some clarifications.
I have the problem with Aero disabled
I have the problem on the Apple site which does not have any flash content.
I have already hacked the lastest nvidia drivers to get them on my system which did not change anything. Can you provide a link to some other 'supported' beta drivers?
I am using the new 13 inch air so it has the newer graphics card so I would expect it to be faster than an old HTPC with a 9400m in it. I wasn't stating that my Air had a 9400m.
It would be great if someone you also do the test to check the cpu load:
- when playing a 720 mkv
- when dragging a window across the screen
Just open task manager and see if the CPU spikes.
Many thanks!

High CPU Usage on Terminalserver (Win2k3)

Hi,
at the moment we are running an Exchange 2010 SP3 in combination with Outlook 2010 (Ver. 14.0.6123.5001 32bit).
Outlook is installed on Windows 7 fat clients, but most users access their mailbox with Outlook running on a Win2k3 Terminalserver (extended support till 2016).
While the users on the fat clients don't have any problems, the thin client users experience problems with high cpu usage.
Following example:
Terminalserver, 12 users, 6 running Outlook, 2 users splitting almost the whole cpu between them (usage around 90-100%).
This makes working on that terminalserver nearly impossible.
I tried safe mode, I tried disabling their add-ins, I tried deleting their terminalserver profile to no avail.
How can I figure out what's causing this?

Hi,
Anti Virus email scanners are known to cause similar behavior, please first check if you have any Anti Virus scanner integrated with Outlook. Try to disable it, and check result.
A corrupted data file might also cause this kind of issue, try to repair your data file with Scanpst.exe tool.
Please refer to this article on how to use scanpst.exe:
http://office.microsoft.com/en-us/outlook-help/repair-outlook-data-files-pst-and-ost-HA102749454.aspx
Please also have a look at this thread, try the workarounds in it and see if issue persists:

Hope this helps.
