Show hidden devices command:
- Click Start, point to Programs, point to
Accessories, and then click Command Prompt.
- At the command prompt, type the following lines, pressing ENTER after each lineset devmgr_show_nonpresent_devices=1where %SystemRoot% is the folder in which Windows 2000 is installed.
- Troubleshoot the devices and drivers in Device Manager, as required.
NOTE: You must first select show hidden devices on the Device Manager View menu before you can see devices that are no longer present in the system.
- When you are done troubleshooting, quit Device Manager, and then close the Command Prompt window. Closing the window clears the variable you set in step 2 and prevents ghosted devices from being displayed when you use the Show hidden devices command.
An alternative approach, for developers or power users who need this feature enabled constantly, is to set this environment variable globally.
To have us set the environment variable globally for you, go to the "Fix it for me" section. If you prefer to fix this problem yourself, go to the "Let me fix it myself" section.
