Hi!I am running Windows XP Professional (SP3).I used two different back up programs in my computer (Bad idea!). As a result, the VSS Service got screwed up and the back up programs didn't work. Someone suggested I run a series of tasks to fix it (listed below), which I did.Is there a way to check if the VSS Service is really fixed?Thank you.Dr. T.Go to Start>Run and type in: command (Then hit [ENTER]) That Will Open Command Prompt Type in this command in dos window: CD \Windows\System32 (Then hit [ENTER]) Then run those commands: Net stop vssNet stop swprvregsvr32 ole32.dllregsvr32 vss_ps.dllVssvc /Registerregsvr32 /i swprv.dllregsvr32 /i eventcls.dllregsvr32 es.dllregsvr32 stdprov.dllregsvr32 vssui.dllregsvr32 msxml.dllregsvr32 msxml3.dllregsvr32 msxml4.dll Reboot your computer.

Hi!I started the VSS Service and I got no errors. Therefore, I assume it's ok.When I restart the computer, it does not show as running, which might or might not be ok. I don't know. The program that I will run - Paragon back up (which uses the VSS Service) - might call the Service on its own. I don't know.The next step is to run the Paragon back up program and see what happens.Thank you.Dr. T.
