[device manager] permanent show hidden devices

Hi there
i would like to permanently enable the view of hidden devices.
Yes, i´ve already set the variable DEVMGR_SHOW_NONPRESENT_DEVICES and yes i know that i have only to click the View menu, and then select Show hidden devices.
But this selection is lost after every reboot.
How to set it permanently?

Hi,
From what I know you cant set the view, show hidden devices permanently. But you can set the DEVMGR_SHOW_NONPRESENT_DEVICES permanently. 
You could open MMC and load in the Device manager snap in. Then select view --> Show hidden devices. Then save that MMC console. If you load that up it will always open with View -- Show hidden devices. A bit of a workaround but will solve the issue ;)
To set the DEVMGR_SHOW_NONPRESENT_DEVICES you need to add it to the enviroment variables.
"Setting the DEVMGR environment variable as described here affects only the instance of Device Manager launched from that Command Prompt window. If you want the change to be persistent, open Control Panel, open System, click Advanced System Settings, click
Environment Variables on the Advanced tab, and define a new variable for this setting. If you add the variable to the User Variables section, the setting will apply only to the current user. If you edit the System Variables section, the extra information will
be visible in Device Manager for all users of the current computer. " 
Hope this helps.

  • I just purchased an ipod shuffle (4th gen.) and  I have been working trying to get it running for hours.  I have followed all manuals and tutorial help.  When I pull up my device manager, it shows an Ipod, but won't let me download the Usb driver.

    I just purchased and IPod Shuffle (4th gen.) and can't get it running.  I have gone through all of the help available.  It shows up in my device manager, but needs a USB driver.  It will find it online, but says an error has occurred and access is denied instead of installing.  I bought this for a last minute trip with teenagers and I have spent hours on this.  I am running Windows 7 and have tried disabling the firewall.
    Help, please.

  • BB Device Manager no hangs when device connected

    I have synced my 9530 & 9550 with Device Manager for over 2 yrs with littie issue.  As of 2 days ago DM locks up as soon as it connects to the device (USB & Bluetooth).  10+ hours of tech support with RIM and they finally tell me its a known software glitch and they have no idea when of if they'll get it solved.  Verizon doesn't even know about the issue.  Anyone else experienced this?

    I had the same problem - After a few years of using a Palm Treo 650, I just received & am switching to Blackberry Curve 8320.  When trying to transfer data from the Palm Desktop to the Blackberry using the device switch wizard, mine kept hanging on Calendar item 1754/2174 (everything updated, synched etc.).  I wondered if this could be due to Blackberry's intentional (?) design to only transfer/synch future calendar items, so I went into Palm desktop & directed it to Tools/Purge Events then chose "Delete events older than 1 month", making sure "Archive Deleted Events at Next Hot sync" was checked.  After this, all old events are retained in Palm archive (which I'm not deleting from drive), and the Device Switch Manager for Blackberry ran successfully.  I also found instructions here to re-set date to an earlier date on Blackberry to allow past calendar events to sync, then re-set the Blackberry to the current date.  This could also be a possible work-around.  Note:  I still plan to sync Blackberry with Outlook now because I like the ability to have larger/different views on the computer screen, like you can with the Palm Desktop.

    Hi luke, I tried your script. However, it seems that once in a while srvnet crashes during the restart. Can you help me on this? Chris
    Hi Chris
    Not sure why that would be but - you could add some error-checking logic to the script to test whether srvnet has successfully started, and then if it hasn't - attempt to restart it again. I haven't tested this code because I haven't had that issue, but something
    along the lines of:
    @echo off
    set logfile="%TMP%\srvlog.txt"
    if exist %logfile% goto begin
    echo [%date:~4,10% %time%] logfile created>%logfile%
    :begin

  • ISE 1.2 patch 5 My devices portal not showing regsitered devices

    Hello Guys,
    I am running ISE 1.2 with all recent patches installed. I have a weird issue where AD users login to mydevices portal and are not able to view any of their registered devices. even thou the devices were successfully registered and onboarded.

    Check your synchronization between your ise nodes, i had a similar issue, that was because ntp had been down for a while, and then the nodes didn't sync the device registrations, and guest users between the nodes.

    hi ktmcmo,
    Are all the USB 2.0/3.0 ports in the front/back part working fine?
    Some other steps that you can try:
    1. Download and run Nirsoft's USBDeview v2.27 (download here)
    2. Create a System Restore point
    3. On the USBDeview interface, right click on the USB controller/hub that's giving you the General Failure error and try to disconnect/uninstall or disable the device and observe if you still get the same error on USBView/Lenovo Solutions Center.
    - Link to picture
     4. If same issue occurs, undo the changes that you have made in Step 3 and make a create a registry backup. On the USBdeview interface, right click again on the USB controller/hub that's giving you the General Failure and choose Open in RegEdit. In the registry, delete the registry key and/or subkey of the failing device and reboot (Windows will automatically re-install the device using the inbox driver).
    - Link to picture
    Note:
    Only do Step 4 if you have a backup copy of your files and have created a system restore point / registry backup.

  • Wrong info in the device manager

    to anyone pls help!
         I'm having problems with the info in the device manager, Its showing 2 hard drives, under disk drives it displays one SCSI Disk Device and one Maxtor 940...? but I only have one hard drive and its not SCSI DISK. why is this?
    do i have a defective board? should send it back?
    SYSTEM:
    MSI K7N2 DELTA ILSR motherboard
    WINDOWS XP PRO WITH SERVICE PACK 1
    10gb maxtor ATA 100
    Elixir 128mb ddr 333
    athlon TB 1800ghz

    By chance, was this system built for you? If so, sometimes shops will keep a fast drive around full of the most current drivers and things so while setting up your PC, they will attatch that drive to load in all the info needed from one source, thus providing you with drivers more current than the ones on the disc that shipped with your hardware. And often, device manager will show active devices that have long been removed. If this is the case,as it was for me,(I had the same prob. till I talked to the techs that built my old systems, since I've been building my own, it's never happened to me.) and the scsi drive is reporting as a secondary drive, I wouldn't sweat it, but it's easy enough to tell the device manager it's no longer there. If this isn't the case, then I hope you do get everything worked out, Good Luck!

  • Graphics Card Does Not Show Up In Device Manager (Re: Installing AMD Video Drivers - Windows 8.1 (Step-By-Step Tutorial)

    This tutorial is a step-by-step tutorial on how to "fix" issues of a new graphics card not appearing in Windows 8.1 Pro, or not appearing (as a device) in Device Manager, or it's not being detected by Windows 8.1.
    This is the "second part" of a Step-by-Step Tutorial on how to install AMD Radeon graphics card drivers in Windows 8.1 Pro.
    GRAPHICS CARD IS NOT DETECTED AND DOES NOT SHOW UP IN WINDOWS 8.1 DEVICE MANAGER
    This problem can appear if the video card is not installed properly in the PCI slot and as a result the card is not detected in device manager. Check the physical connections again, reinsert the card properly in the PCI slot, check the connections (including the power cables going to the video card, and ensure that the fan on the graphics card is spinning and the card does have power and is properly seated/inserted) and then install the drivers from the manufacturer’s website.
    If the video card is in fact installed properly, but the problem of the video card not being discovered/found by the operating system persists, then try these following methods below to check if this solves the problem.
    Method 1:
    First, I would suggest you to run the following Microsoft Fixit to get the problem automatically detected and fixed. This Microsoft "fixit" App checks if the device is currently disabled or turned off or the driver is not installed.
    Hardware devices are not working or are not detected in Windows.
    http://support.microsoft.com/mats/hardware_device_problems/en-us
    Method 2:
    Sometimes, some devices in device manager are hidden due to corrupt or missing drivers.
    Follow the steps below to show hidden devices in the device manager and troubleshoot accordingly.
    Press the Windows key + X
    Select Command Prompt (Admin)
    Type set devmgr_show_nonpresent_devices=1 and hit enter
    Type Start DEVMGMT.MSC and hit enter.
    Once in Device Manager hit the View menu and select show hidden devices.
    From here, remove each instance of the AMD or Nvidia card you see as well as each unknown device. Exit Device Manager and reinstall the latest drivers you can find for your graphics card.
    After you install the drivers, reboot and see if you get any different results.
    If the above solved your problems and the Graphics Card is now working and is now being properly detected/displayed in Windows Device Manager:
    If your graphics card is now being detected by Windows 8.1 in Device Manager, but has a "yellow exclamation" mark (or video drivers are not found or not properly installed or the device is disabled) then install the latest graphics card drivers and proceed with this Step-by-Step Tutorial on how to install AMD Radeon graphics card drivers in Windows 8.1 Pro.

  • URGENT Lenovo g550 webcam does not show up in Device Manager and all drivers cannot be installed

    Hello everyone. So my lenovo g550 webcam stopped working after I did a clean install of windows 7 home. When I go under device manager I do not see any unknow devices. When I also go to show hidden devices it is not there. Could anyone give me information about how to fix this and if the cable to the webcam might be broken. If so, is there a way I could convert the webcam's pin outs to usb to test it. I have split an old usb cable into four colored spots. Not sure if i want to test it though. That would be my last resort. If needbe, can you tell me the pin outs for the webcam. It has five connectors. The reason I know this is usb is because my older installation on windows 7 detected it and said that the usb could be faster. Thanks.

    Sorry about that. I've only been a member for a few days. I will remove the post with all Capps. Have a nice day!

  • HP Envy dv4 Windows 8- HP TrueVision HD Webcam not working or showing up in device manager

    The subject is fairly self explanatory, I am using a HP Envy dv4 on Windows 8 and trying to use the 'HP TrueVision HD ' Webcam which is not working. When I went to find it in the device manager it was not present. I have restarted my computer already.
    Thanks

    Hey @kleinhansjy ,
    Welcome to the HP Forums!
    I understand the webcam in your ENVY dv4 notebook is not working.
    Can you tell me if the webcam worked previously, has never worked, or stopped working after updating to Windows 8 (if the notebook did not come with Windows 8 pre-installed).
    It would also help to know which exact notebook model you have. For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number?
    While I await your answers please try following these troubleshooting guides:
    Webcam Troubleshooting (Windows 8).
    Fixing Webcam After Changing the Operating System.
    Some of the steps may not apply if the webcam is not detected in Device Manager. You may need to show the hidden devices by clicking View > Show hidden devices. You might find the webcam is listed as an Unknown device in the Other devices category.

  • Device Manager Doesn't Show Speakers

    I used my device manager to disable my speakers and mic about two months. I figured I could easily enable them when I was done with what i was trying to do. When I went back to my device manager, my speakers and mic were not there. Now when I put my cursor over the sound icon (with the red "x"), it tells me "No Audio Output Device is Installed." Many people have told me to install drivers, that doesn't work. Some say i should uninstall my audio from the device manager and restart my computer, but my speakers DO NOT appear AT ALL in my device manager. Where did my speakers go?

    In Device Manager have you tried View,and select 'Show hidden devices' to see if they show up?

  • Dv9913cl Notebook not showing DVD drive in system or Device manager, and more

    I recently reinstalled the operating system on my stepfathers Pavillion dv9913cl notebook because it was slow and old. After I reinstalled windows I installed all of the drivers from HP's website, and made sure windows was completly up to date. I checked to make sure things on the computer worked, but I forgot to check the DVD drive.
    So today when he went to put in a DVD it did not work. I was not present when he and my mom first tried using it, but this is what they passed on:
    After putting in a DVD it took a few seconds and then something(I couldn't get them to tell me what) popped up saying something about the DVD region. I couln't get a clear answer on what it told them. My mother said something about it being the wrong region and something about selecting things like US English, and I don't know how what actually popped up for them. I also don't know were this path took them and ended.
    Next apparently my mother went searching online. She found a Ask Yahoo that I couldn't relocate that told her to go into help, about windows media player. Then to go to Organize, then layout and show menu bar. Then step two she wrote down is About Windows Media Player -> tech.supportinfo. Specific File to determin codec. Right click file in Library - Properties on file tab - Audio Codec/Video Codec. (I don't know what she was attempting to do here and couldn't get a straight answer. I think the ask yahoo post told her she couldn't play the type of file because of a missing codec, but I dont think that is the problem, I inlcuded what she did though incase somehow it did something bad)
    She did some other searching and tried to get into device manager I think to see what it said about the DVD device, but I am not 100%.
    **So this is the poiny where I come home. I sit at the computer and pull up device manager.  The DVD device is not listed. I looked at every single entry in device manager, nothing has an exclamation point, and nothing says DVD/CD device or anything close. 
    I went to HP driver website and pulled up the drivers for this laptop. There was not a particular driver there for the DVD player.
    I resarted and went into the BIOS and went to the boot order options. The DVD drive does show up there. (I made no changes)
    When I insert a DVD or CD nothing happens. I can hear the drive spinning, but nothing happens on the OS. nothing pops up. It doesnt show up in my computer, and I can't find the DVD or CD to play through any program.
    I found this support article. https://support.microsoft.com/kb/314060
    I tried all 5 of the resolutions. For resolution 3 I got to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}, but in the right pane there was nothing that said either UpperFilters or LowerFilters. When I did some searching I found some other people who had similar problems and fixed it by doing what is suggested in resolution 3 and deleting the entries for UpperFilters and LowerFilters, but they were never there for me to begin with.
    Now I am at a loss on what to do next. It seems like when he first put the DVD in the computer it was recognizing the DVD since it said something about DVD region it must have known a DVD was in there, but I never saw that screen. By the time I got to the computer nothing happens when I put any DVD or CD in.
    I apologize for the long post, and thank you for any help that can be provided. (Also I don't use Windows, so please try and explain things as layman as possible.)

    Hello RonFishing,
    Welcome to the HP Forums! I hope you enjoy your experience!
    I understand the computer appears to be unable to play DVDs, and the required driver in Device Manager is not found. My response will not be as long as your post, but I will do what I can to assist you!
    I do not know what Windows operating system you are running. This will be important in resolving the issue. In the meantime, I welcome you to try the steps in this HP document: Resolving DVD and Blu-ray Movie Problems (Windows 7)
    Even though the document is for Windows 7, the steps are similar amongst all versions of Windows. Please try the steps and let me know the results.
    Thanks for choosing the HP Forums. Have a great day!

  • Wireless adapter not showing up in device manager

    Hello all,
    I am having a particularly frustrating problem. I was playing around with the memory timings to overclock my computer and all of a sudden, my wireless adapter ceases to exist to my computer. It does not show up anywhere in device manager (including no unknown devices or anything), only the Ethernet shows up. I have tried a system restore, turned off all OC and my BIOS is updated to the most recent version. Is it possible that trying to overclock my computer caused the wireless adapter to burn out? The motherboard I'm using is the msi x99S gaming 9 ack.
    Any help would be very appreciated, thank you all in advance for your time to help out!

    remove power cord from the PSU and >>Clear CMOS Guide<<
    if the wifi card is removable, try to reseat it
    also install latest killer drivers from:
