Keyboard stops working after "switching user"

Question

Hi,

On a few PCs within my organisation, we are having the following issue.

If you are signed in and then decide to switch user, the keyboard stops working and you have to unplug it and plug it back in (at times you have to restart the entire PC).

I have tried updating drivers and disabling power management for the USB ports but this has not resolved the issue.

Grateful if somebody could advise on this issue and provide any potential solutions.

Fast User Switching allows multiple users to switch quickly between accounts, but it can sometimes cause conflicts. Try disabling Fast User Switching to see if that resolves the issue.

Press Win + R to open the Run dialog.

Type "gpedit.msc" and press Enter to open the Local Group Policy Editor.

Navigate to "Computer Configuration" > "Administrative Templates" > "System" > "Logon."

Look for the setting "Hide entry points for Fast User Switching" on the right side and double-click it.

Select "Enabled" to disable Fast User Switching.

Click "Apply" and "OK."

You can create a new user profile on your computer and see if the issue persists in the new profile. If the keyboard works fine in the new profile, it may indicate that there's a problem with your existing user profile.

Hello

Based on the information you have provided, it seems that the issue could be related to the USB port or the keyboard itself. Here are some troubleshooting steps that you can try:

1. Try using a different keyboard on the affected PCs to see if the issue persists. If the issue does not occur with a different keyboard, then the problem could be with the original keyboard.
2. If the issue persists with a different keyboard, try connecting the keyboard to a different USB port on the PC. If the keyboard works fine on a different USB port, then the original USB port could be faulty.
3. Check if there are any pending Windows updates and install them. Sometimes, updates can fix issues related to hardware.
4. Try running the Hardware and Devices troubleshooter. To do this, go to Settings > Update & Security > Troubleshoot > Hardware and Devices.
