Did You Know (#2: Hidden in the Device Manager)

Whenever you unplug a device from your computer, it stays hidden in the device manager, even though you don't see it. What can this do? It clogs up Windows and slows it down.
If you want to uninstall this clutter, try doing this:

- Click on Start and type in CMD to reach the command prompt. Windows XP users might need to click on Start > Run.
- Type in set devmgr_show_nonpresent_devices=1, then press Enter.
Now close the command prompt and click on Start > Control Panel > Device Manager. Click on View, then select Show Hidden Devices.
You'll now want to expand each category and remove any device in which the icon isn't a solid image. The text will still be black, so don't get yourself confused.

There is no harm in doing this as they are no longer in use by your computer.

Next, open device manager (Click Start Menu and type in "Device Manager", right click and run as administrator). Then find your device in the list, and uninstall it. Immediately, unplug the wireless USB from the computer. Now, restart your computer with the USB unplugged. Insert your driver disk and install the driver, when prompted plug the wireless USB back into the computer. Hope this helps.

Wireless adapter is disabled whenever computer is in sleep, hiberate or shutdown. In other words, every time you log on you need to troubleshoot because the wireless adapter is disabled even though in the device manager it indicates that wi-fi IS enabled. Any suggestions?


  1. Go into device manager, right click the adapter, and go to properties.
  2. If there is a power management tab, click it and uncheck "Allow the computer to turn off this device to save power"
If this does not work please let me know the model of your adapter. Thank you.

Computer doesn't detect printer on installation


is it a usb printer? if so follow this:
Device Manager displays only non-Plug and Play devices, drivers, and printers when you click Show hidden devices on the View menu. Devices that you install that are not connected to the computer (such as a Universal Serial Bus [USB] device or "ghosted" devices) are not displayed in Device Manager, even when you click Show hidden devices.

  1. Click Start, point to All Programs, point to Accessories, and then click Command Prompt.
  2. At a command prompt, type the following command , and then press ENTER: set devmgr_show_nonpresent_devices=1
  3. Type the following command a command prompt, and then press ENTER: start devmgmt.msc
  4. Troubleshoot the devices and drivers in Device Manager.

    NOTE: Click Show hidden devices on the View menu in Device Managers before you can see devices that are not connected to the computer.
  5. When you finish troubleshooting, close Device Manager.
  6. Type exit at the command prompt.

    Note that when you close the command prompt window, Window clears the devmgr_show_nonpresent_devices=1 variable that you set in step 2 and prevents ghosted devices from being displayed when you click Show hidden devices.
If you are a developer or power user and you want to be able to view devices that are not connected to your computer, set this environment variable globally:
  1. Right-click My Computer.
  2. Click Properties.
  3. Click the Advanced tab.
  4. Click the Environment Variables tab.
  5. Set the variables in the System Variables box.

my sony nwz-S616F doesnt transfer songs from pc

Dear holders, I have it and solved all problems which are in discussion. Just read all INFERNAL help, it works! By XP, go to Start-Control Panels-Administrative tools-Computer Management-Device manager (small icon of computer on your left hand side) tab should have “Walkman” or MTP device. Right click on it and go to properties, now before doing anything it should say “Location — —— Location 0 (Walkman)” if not try unplugging the walkman and see if the MTP device you’re looking at is removed from the list, just to make sure it’s the right device we’re looking for.If you’ve confirmed it’s the Walkman, click on the “Driver tab” and click on “Update Driver…”. Then click on the “Install from a list or a specific location (Advanced)” option and click “Next”. Now select the “Don’t search. I will choose the driver to install.” and click next. It should now bring up 2 driver choices, one being “MTP Device” and the other “USB Mass Storage Device”. Select the USB option and select next, it will then install your walkman as a USB storage device and after that’s done. It should be a matter of unplugging and plugging the Walkman back in and it should show up on your storage options in “My Computer””. Holla for original uploader Inferno!!!
