I was trying to uninstall a print driver for a network printer for one of my users (Windows 7), and I ran into that issue where it tells you that it can't remove the drivers because they are still in use (this after stopped and restarting the spooler, rebooting, etc.). So I was looking at the "File Repository" for this print driver (C:\Windows\System32\DriverStore\FileRepository\hpcu115u.inf_amd64_neutral_4a9d334b04ff58b2), and it has the same files as another folder that is pointed to under the "Driver" tab in the Print Server Properties dialogue (C:\Windows\system32\spool\DRIVERS\x64\3). My questions are the following:
1. What is the purpose of the File Repository folder as compared to the driver folder as listed above?
2. If I am unable to remove the print drivers through Print Management (using admin rights), should I manually delete the corresponding File Repository folder, should I delete the files in the corresponding folder as listed above (C:\Windows\system32\spool\DRIVERS\x64\3), neither, or both?
3. Why in the world does it give that message, even after having deleted that printer? Is it a matter of other users on that machine being mapped to that same network printer, or what?
Thanks for your help!
