Virtual PC 7.02 - Windows XP vs. Windows 2000

I'm new to Virtual PC for Mac and have noticed a huge difference
between running Windows 2000 vs. Windows XP in it. Windows XP runs a
lot slower, almost to the point of uselessness. I have the memory for
both allocated up to 512MB. Does XP just not work as well or is there
a setting that I need to change to correct the issue.
Thanks for any tips!

Sorry guys, forgot to post the link.....

The storage where the virtual hard disk is located does not support virtual hard disk sharing. (Hyper-v / Windows 10 Enterprise Tech. Preview)

I am attempting to create new virtual machines in Hyper-V on Windows 10 Enterprise Tech. Preview and I am continually getting the error "The storage where the virtual hard disk is located does not support virtual hard disk sharing.". I am not trying

Should I download windows 7 or windows 8 release preview using parallels, should I download windows 7 or windows 8 release preview using parallels

I downloaded parallels and was given the option to download windows 7 or window 8 release preview. I have heard of people runing thier macs by downloading the release preview, but don't have a liscense of windows 7. If I buy windows 7 i will have to pay to upgrade to windows 8, but if I download the release preview I will be unable to use it after September 26 whan Microsoft releases windows 8. Then I will have to pay full price for windows 8. I want to know which is better to do because I need it for school next week.

Buy Windows 7 retail disk and use the 64bit disk to install into Parallels. This verison of Windows is well supported an there is lots of software your school is likely using it on.
Windows 8 is still in beta stage, not ready for everyone to use yet. However you CAN download the devlopers preview issue also to play around with.
http://osxdaily.com/2012/03/03/try-windows-8-consumer-preview-virtualbox/
WIth Virtual Machine software you can install many other operating systems and use any (or many depening how much RAM and storage space you have) at the same time.
So you can use Windows 7 and your schools software, and then quit that and play around with Windows 8, or Linux verisons too.
Windows in BootCamp or Virtual Machine?

Can I install Windows 7 and Windows 8 to my MBA using Parallels and Bootcamp?

I have a Macbook Air (latest model, 11", i7, 256gb, 8gb ram, Mavericks).
I need to have access to Windows 7 and 8 and have been toying with the idea of getting a cheap laptop but the problem is most new machines are Windows 8 and they won't allow you to dual-boot with Windows 7 (you need W7 as your main OS and then install W8 later).
I'm also keen on not spending a shedload extra and carrying another device, so I was thinking if this was possible:
Buy Parallels Desktop 9 - then either using bootcamp or not, Install both Windows 7 and Windows 8.
I'm not fussed about running everything at the same time, happy to shut one VM down if it helps performance.
I have read that multiple OSs such as vista and XP worked once upon a time, but I get the feeling the screw is being tightened with all these cross OS installs and didn't want to drop a couple of hundred quid only to find out I'm trying something that isn't possible.
thanks for your advice.

I can't help you with Parallels, but I've been using VMware Fusion for quite a while and you can run Windows 95 through Windows 8.1 without difficulty, so Windows 7 and 8 on the same Mac is easy to do. I think your biggest difficulty will be the small size of your SSD. But with virtualization, you can put the virtual machines on an external SSD connected via USB 3.0 and run them quite well.

Disabling SMB2 and SMB3 Client from Windows Vista, Windows 7 and Windows 8.

There are many programs that are using a shared file on the server from clients from XP to Windows 10. From time to time it seems like there is a network outage and the handle to the file is broken and the file
cannot be read or updated. It seems more prevalent on a Windows 2012 server but may have happened from time to time on 2008 & 2008 R2. However there are not any network problems so it just leaves the server & Client
I have searched for possible resolutions including:-
Turning off the Cache for the share
Disabling the network adapter power setting to allow windows to put the device to sleep.
Disabling Antivirus/configuring it to ignore folders for on access scanning
Disabling SMB Signing
Configuring the clients DWORD registry value SilentForcedAutoReconnect=1 in HKEY_LOCAL_MACHINE\Software\Microsoft\CurrentVersion\NetCache
Setting the "NET CONFIG SERVER /AUTODISCONNECT:-1" to not drop client
connections
The last bit of trouble shooting that I can think of is to disable SMB2 and SMB3 as that does a lot of caching and batching of packets which could also be the cause of the problem.
I have looked at
http://support.microsoft.com/kb/2696547/en-us
I have disabled SMB2&3 on the server as that is very straight forward.
When I get to the section about disabling SMB2 on the client the command fails.
sc config
lanmanworkstation depend= bowser/mrxsmb10/nsi
  After running the above command, it returns an error:
      [SC] ChangeServiceConfig FAILED 1059:
      Circular Service Dependency was specified.
So it's not worth running the following command:
sc config mrxsmb20 start= disabled
I have tried the command on Windows Vista, Windows 7 and Windows 10 just to confirm that it's nothing to do with any particular PC, machines in Domains and Non-Domain machines.
So, my questions are:-
1, is
http://support.microsoft.com/kb/2696547/en-us actually correct and up to date and for the OSes (Vista, 7, 8, 8.1, 2012 server and Windows 10) with latest updates & service packs?
2, How do I disable SMB2 and SMB3 on clients for troubleshooting purposes the server to resolve problems with shared files (multi user access)
3, If I just disable SMB2 & 3 from the server would that force the clients not to use SMB2 when communicating with the server and therefore not caching the directory structure and file not found etc? I have seen posts that suggest this is not the case.
4. Does sc.exe have a bug in it?
Thanks in advance
Rob

Hi,
I made a test in our testing enviroment, everything works fine to disable SMB2 and 3. For your problem, in my opinion, as I didn't find any specific report about this error, it would be better to use Process Monitor to capture the trace when running the
command.
Start Process Monitor, then set the filter as cmd.exe, after that, open CMD and execute the command.
Process Monitor:

In addition, I found another thread that had similar error with yours, you can take its solution as reference.

Roger,
Many thanks for the time taken to look into this.
I've downloaded process monitor and loaded it. I filtered for cmd.exe started capture and saved a 1mb file.
However I don't think this is going to help unless you can point me in the direction of what you're expecting to see in the capture file? If you want me to send you it I can but it does contain personal information which I'd rather not place online.
You can recreate the problem yourself by doing the following:
Go to modern.ie
Download any windows 7 virtual machine for your preferred of virtualisation platform
log in, start cmd as administrator and run the command
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi
You will also receive the same error.
[SC] ChangeServiceConfig FAILED 1059:
Circular Service Dependency was specified.
You can also try it on the Windows 8 and 8.1 machine if you have time.
I checked the link to the similar error and that just looks at the file not found problem which is the smb2 cache. They still didn't resolve the slow access to the share which is seen on a machine that has anti-virus on it when you go to right click
on the folder or a file in the folder. It's about a 20 second (spinning circle) pause every time. The problem is bigger than that. If you have shared files on the network share that are used by multiple people at the same time, say a spreadsheet or database
file windows is loosing the connection to that file so the user cannot write to it even if they have the file open. The smb2 caching shouldn't cause that problem.
It appears that I have to disable from SMB2 and SMB3 and ensure that the clients only use SMB1.
If SMB2 & SMB3 are disabled from the lanmanworkstation service the clients will not do any caching even if the server has disabled the share cache (offline files for that share).
The problem with the "Circular reference" error message is standard across all versions of windows that have "smb2" or "smb2 and smb3". Can you recreate that problem? Or is it working on your windows computer and on the machines
downloaded from modern.ie ?
My testing has shown that the command "sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi" does not work. Therefore that's the one I want to resolve first. By resolving that I may be able to get the clients accessing the share to behave
themselves and use the shared files correctly as they always did from Windows 95/NT4 through to Windows XP and 2003/2008 server.
I'm unable to recreate the problem with multiple users having access to shared database files on windows 2012 server from Windows 7 clients were the access to the files drops once a day or once every couple of days.
Kindest Regards
Robert

Windows 10: Open Windows Are Resized When The Lid Is Closed

I have just done the free Windows 10 Pro upgrade. Everything seems to be working fine; except for this issue. Every time I simply close and re-open the laptop lid, the open windows are resized. Most windows get restored to where they started, yet they seem to ALL have been resized and then sized to their previous location. You can tell because minimizing / restoring windows does not remember the actual last size that you used. But some windows DO NOT get resized back where I left them. Chrome in partiular becomes crazy. Sometimes the window becomes maximized; and other times it gets sized to a smaller rectangle at the top left of the screen. You can see all the windows flicker and jump around when you re-open the lid. ... My laptop is the ThinkPad W540. MsInfo32: OS Name Microsoft Windows 10 Pro

Minor update: I performed another Windows 10 reset: I reset the operating system, keeping User Files. So the system got re-installed. I ran Windows Update until all updates came down. I also ran the Lenovo System Update and installed all updates. Specifically, at this point, I haven't gone looking for additional drivers, such as the graphics drivers --- and on this dual-graphics, there is no control panel for the high performance NVIDIA GPU ... I don't know if that is making any difference. The bug DOES persist; but behaves marginally different at this point ... at least, the open Chrome window no longer resizes; and the Task Manager doesn't move; but other things still jump around, and the open Control Panel window becomes duplicated. Again, this is just by closing and re-opening the laptop lid. The Lid-Closed behavior is set to "Do Nothing"; and the Intel Graphics is set to High Performacen mode. ... So I don't know if they do, but I would not understand why the graphics would switch when the lid closes: they still might. I have another video that captures the behavior. Again: there is no Lid-Closed action, and just closing and re-opening the lid causes the resolution to switch back and forth. YouTube: https://youtu.be/Qapt3ZyOVE4 ... I would like to see this cured, since it is truly a very annoying bug! Your work becomes disrupted simply from closing the lid.

Can you upgrade windows xp to windows 7, can you upgrade windows xp to windows 7

Can you upgrade windows xp to windows 7, even if you partioned your HD with windows xp?

And if that doesn't answer your questions, the answer is "yes, yes" -- but you'll have to do a clean install rather than an "upgrade". I believe you can only go from Vista-> 7, but double check that. You sure the hardware can handle the jump from XP to 7?
A quick expansion on that, they both can use the same or different filesystem formats (for instance, XP might use FAT32 or NTFS... whereas Win7 will most definitely want to use NTFS at least). Not to mention FAT32 would cap your usable hard drive capacity because of mathematical limits (so would NTFS eventually, but these days, with FAT32, you'd notice it.... unless they use some addressing extention mode -- no need to even talk about that).
One definite thing is they will use two different boot loaders. The old using NTLDR and the new using the BOOTMGR/GUID booting uhm... they're just two different mechanisms and monsters -- but you CAN run Windows XP and Windows 7 side by side within your "Windows" partition-- that is a possibility. So you'd literally have a dual booting dual boot machine, haha... Choose OS X or Windows, then have to choose XP or 7. Good luck, buahaha... don't end up in the wrong version of Windows... it could ruin your week! (Official "wrong version" #1 is Windows ME, second official "wrong version" is Windows Vista. I was made to use both at differing points. God help me, I think it left lasting damage).
You actually have a Mac and want to use Windows? Why? LOL. Let's trade. I'm using Windows 7 and would much prefer it be OS X! Actually I was cleaning all of these orphaned folders, DLL files, leftover temporary garbage files and registry keys left behind as a result of using a PC for any period of time... In fact, my virtualized OS X Snow Leopard runs faster being EMULATED than the actual host OS itself! Bass ackwards, that one!

If I reboot to Windows directly from Windows (bootcamp options), I cannot launch a vm in Hyper-V

Hello guys,
If I reboot to Windows directly from Windows (bootcamp options) or press "option" key and select Windows after power on iMac, I cannot launch a vm in Hyper-V anymore (the Windows Phone 8 emulator to be precise). It says hardware virtualization is not enabled in BIOS.
When I boot Windows from OS X > Startup Disk > Boot Windows or boot OS X and reboot iMac and boot Windows after press "option" key and select Windows, I can launch a virtual machine in hyper-V, so that's cool.
How it fix? Any ideas?
iMac (27-inch, Late 2013), Windows 8.1, OS X 10.9-10.10
Boot Camp Support Software 5.1.5621

You should always use System Preferences -> Startup Disk. It enables the CSM-BIOS layer. When you use the Option Key, Windows will come up, but underlying CSM-BIOS layer is not invoked. The Hyper-V depends on BIOS settings, it will only work when using the Startup Disk option.

Windows Contacts and Windows 8?

This is a question for people on the operating system team: What is the role of the Contacts Folder in Windows 8? Do the Contacts sync with the metro People app, Windows Live Mail, or Windows Messenger? If not, is it pretty much an abandoned
feature?

Hi,
In Windows Live Mail, it will sync Windows Live Messenger contact and Windows Contacts. Regarding People app, it just sync Windows Live Messenger contacts default, it won't sync Windows Contacts on local computer.
The role of the Contacts folder is same in Windows 7

Windows Vista and Windows 8

I have a Windows Vista Full Installer disc and a Windows 7 Upgrade Disc. I am currently running a Mid-2012 MacBook Pro 13" with Mountain Lion, Boot Camp Version 5.
Can I install Windows Vista through Boot Camp, then upgrade to Windows 7 or Windows 8 when it's released?
Thanks.

Vista is not supported with Mountain Lion. You could try installing Windows 7 over itself. Some have reported success doing this.

Windows 7 and windows 8 desktop wired and 7510e printer connected to win 7 wireless

I have a windows 7 64 bit HPavilion Elite 150f desktop set up wired with a 7510e photosmart printer connected to it wireless, now I have purchased a windows 8 desktop HP envy 700-019 desktop.
When I set up my new windows 8 desktop I just plugged it into my wireless router/modem combo and it found my printer and I could just print from it, I did not download any software or drivers for my printer or set up a home group as I was not sure how to set it up but last night I tried to set up a homegroup,
I used my wireless network key and entered it and pressed connect, then I entered the Homegroup password that was downloaded for me from Microsoft, but my windows 7 says homegroup and my windows 8 shows private network so I am not sure what I have done wrong, I chose to only share music and printers, can anyone tell me how to do this correctly as I am not sure that I have done it properly.
On my windows 8 I can go to my printers web site by entering the static IP address that cloud support set up for me and it shows as connected but I do not want to enter any printer code as that is already set up on my windows 7, I can also scan to email on my windows 8 but I am not sure what if any security I have on my windows 8. The last time I had a homegroup set up I payed someone to do it for me so I did it by guess work more than anything, if someone can lead me through it step by step I would appreciate it.

Hi @emma22
I would like to do my best to help, but please bear in mind the issue you are expressing is an inquiry for Microsoft not HP. I did find something I think will be most helpful, and I hope it resolves the issue, but if the issue persists, or you have additional questions, it might be best to reach out to the Microsoft community.
Here is what I found; HomeGroup from start to finish.
In the top right hand corner of the article, you can change it from WIndows 7 to Windows 8. I hope this helps.

Windows 7 and Windows 8 in the same computer

I have HP Pavilion HDX9300 with two hard discs. I have installed Windows 7 in och of them and Windows 8 in the other. Both W7 and W8 works when the disc is placed in one of the discplaces but not in the other.
If I want to change from W7 to W8 I thus have to change place for the hard disc. My desire is to change from W7 to W8 without changing places for the harddiscs. Is it possible? If so, how do I do?

I believe the second hard drive bay in the HDX9300 is not bootable. You need to load Windows 8 on the same hard drive as Windows 7 as a dual boot.
http://www.extremetech.com/computing/143380-how-to-dual-boot-windows-8-and-windows-7
You could then use the second drive as storage accessible to both operating systems.

How to downgrade from Windows 8 to Windows 7

I recently purchased a T430 with Windows 8 loaded. After I played with Windows 8 for a few days, I regretted that I had not ordered the Win7 version. I have a Windows 7 Proression edition CD, so without too much research, I thought I could just easily install the Windows 7 over Windows 8 and be done. What a fool I was! And let me share my failure experience so no same mistake would be made by others who wanted to do the same:
First, I tried to put in a Windows 7 CD and run installation from the CD; sure, it failed quickly.
So, I went into the BIOS and changed the Startup setting "UEFI boot" only to "Legacy boot" so it will force the machine to boot from my Windows 7 CD. That little bit of advanced setting was taking me to death row a bit faster, as matter of fact. Read on...
Restarted the machine and now I was able to launch the Windows 7 installation screen. I was too excited and moved along to the point it asked if I wanted to delete the partition. In the past, when I reinstalled OS, I always said yes to delete the old partition and created a new partition. But man, I was so ignorant of new technology! Windows 8 is no longer NTFS. It is on GPT (Guid Partition Table) format now. But somehow, it did allow me to delete the main partition where Windows 8 was installed. No error message or warning message that seemed critical popup, the partition just went into a limbo.
All hell broke loose from then on. Windows 7 could not install on GPT partition and I could not go back to Windows 8 now that its home base (GPT partition ) was damaged by Windows 7.
After some Google search and serious read, I found postings suggesting downloading a GPARTED iso image, burned that to CD and run it from CD drive to re-partition the damaged GPT on my machine. I did all that, had the CD created, put it in the drive and waited for the magic....but No way, it did not work - it simply sit there and NOT bootable. I could go into to command line and tried to run every possible .exe or .bat file in the disk, but no thing worked.
So the miser goes on. I had tried to call Lenovo tech support at 1-800-426-7378 and guess what I ended up? - a series of busy dial-tones...
Community forum, my last resort! Hereos please come forward and help!!! Just don't tell me to download the GPARTED, burn it to CD or USB and boot from there....
Solved!
Go to Solution.

Bill， I really appreciated that you pointed me to the DiskPart utility that is part of DOS. With that, I have successfully overcome the biggest hurdle - re-partition my disk to NTFS format. Here I recorded the steps I went through:
Powered up T430 and let the Diagnostic tool run "Preparing Automatic Repair"
On screen showing "Diagnose your PC" then "Attempt to repair your PC"
Automatic Repair failed, then two options button showed "Shutdown" and "Advanced options"; selected the "Advanced options" button
Selected "Troubleshoot", then "Advanced Options"
Clicked on "Command Prompt" on Advanced Options screen
Now we are in command prompt: c:\>; typed "diskpart /?" to list a possible commands
Followed the instruction on http://www.computerhope.com/diskpart.htm to get the proper command switch
At C:\> typed "diskpart" to enter DISKPART command mode; then type ? to list all the switches, such as GPT, Help, etc
Diskpart>format fs=NTFS Label="86DB-AC90"
Did not format; message returned
There is no volume selected.
Please select a volume and try again
As matter of fact, the problem was that I had not selected a disk; after reading this post at http://www.jwgoerlich.us/blogengine/post/2009/11/05/Use- Diskpart-to-Create-and-Format-Partitions.aspx, I did a "list disk" command at DISKPART>, and that got me a list of disk online.
Then I did a select disk command: DISKPART>select Disk 0; it returned message "Disk 0 is now the selected disk"
I ran "clean" command again; this time, message returned, "DiskPart succeeded in cleaning the disk"
Diskpart>format fs=NTFS quick; still got the "There is no volume selected"
Tried DISKPART>convert mbr
DiskPart successfully converted the selected disk to MBR format
DISKPART>create partition primary
output: DiskPart succeeded in creating the specific partition
DISKPART>select part 1
output: Partition 1 is now the selected partition
DISKPART>format fs=NTFS label=YangT430 quick
Put in Windows 7 32-bit CD and installation now just sailed through.
