PM leaves Windows in quasi safe mode

Hello,

I have used PM 11 to modify partitions on my HD. After restart and offline completion of the operation, Windows 7/64 reloaded in normal mode, but with a number of services and drivers inoperative. When trying to start such services, the error message was that the services could not start in safe mode.

After investigation I found that an Option subkey had been added to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot.

After deleting that subkey Windows restarted normally.

Question: is PM responsible for adding that subkey ? If yes, why ?
