Many of us have been  using msconfig  to get rid of unwanted startup programs .It has worked using the startup tab to disable programs until recently . Even though you are logged as a user that has admin privilege ,suddenly when you start the program you may  get 'an access denied error was returned while attempting to change a service. You may need to log on using an Administrator account to make the specified changes'

3.If you have or share HP printers, especially the HP PSC 2100, 2200, 4100 and 6100 series, you may receive this  error.The culprit is a security update for the HP printer software.PML Security Update pmsvptch.exe  causes a service "PML Driver HPZ12" to start in services.msc which would interfere with the rights/privileges.


The HP printer software may load a service named PML Driver HPZ12, which is added to the services section of msconfig. This service handles many functions pertaining to the communication between the computer and the printer. However, many of these functions are not related to printing, so you can fix the “Access Denied” error by disabling the service.


1. Srart>Run> regedit
2. Export registry to make a backup (as a precaution)
3. Open HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/PmlDriver HPZ12/Start
4. Right Click and select modify
5. Change value to 3 for manual (or 4 for disabled )
6.Restart computer
