If you are receiving this error message: “An Access Denied error was returned while attempting to change a service, You may need to log on using an administrator account to make specific changes,” you will want to do this:
1. Go to regedit via start..run…regedit
2. Export registry to make a backup (in case something goes wrong!!)
3. Navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Pml Driver HPZ12/Start
4. Right click and select modify
5. Change value to 4 for disabled (or 3 for manual…I did 4)
6. Restart computer
