Fix VSS Error using VMconverter for WIndows without reboot

REF

We have been having issues with certain Windows 2003 Systems (Both 32bit/64bit) failing backups when the "Microsoft Software Shadow Copy Provider" goes into a hung state i.e. "Stopping".
We have have a workaround short of a reboot.

c:\tasklist /svc | findstr swprv

1. Click Start, click Run, type Regedit, and then click OK.
2. Locate and then click the following registry subkey:
