print spooler service problem

[Guest OM]

The print spooler service cause instability on my Vista machine. When

the service is running, the Windows Sidebar doesn't work (no gadget show

up and can't add any). When I try to launch Adobe Reader/Acrobat,

nothing will happen. If I stop the print spooler service, all these

problem will be gone. I was told that I could have some corrupted print

drivers installed and it needed to be deleted. I tried enabling the

print spooler service, but all the printers are not there, and again I

can't add printers and do any printer related tasks.

 

Anyone has an idea?

 

Thanks
