When adding a printer you receive an error that says, “Windows cannot connect to the printer. Operation failed with error 0x00000002”
Unfortunately the only thing I have ever found to resolve this is restarting the print spooler service.
When changing the drive letter in Disk Manager you may receive an error that says, “The parameter is incorrect”.
This can happen is the pagefile is on that drive. Move the pagefile to a different drive, reboot, then try again.
