Restore Default Startup Configuration for Hyperkbd

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config hyperkbd start= demand

3. Close the command window and restart the computer.

The hyperkbd service is using the hyperkbd.sys file that is located in the %WinDir%\System32\drivers folder. If the file is corrupted or deleted, you can put it back in there.
