Windows Backup and VSS - part 3

The saga continues...

Per the folks at Microsoft PSS, there's a rollup package for VSS at This is a hotfix, so note that regression testing is not complete and you should proceed with caution. You'll need to reboot after installing this package.

After the reboot, you'll need to re-register VSS's corresponding DLLs. Enter each line in a command window and press enter after each.

cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 ole32.dll
regsvr32 oleaut32.dll
regsvr32 vss_ps.dll
vssvc /register
regsvr32 /i swprv.dll
regsvr32 /i eventcls.dll
regsvr32 es.dll
regsvr32 stdprov.dll
regsvr32 vssui.dll
regsvr32 msxml.dll
regsvr32 msxml3.dll
regsvr32 msxml4.dll

(the last entry may not run successfully)

Reboot the server again.

This procedure may not be applicable to your situation, so back up your system before proceeding.
