Office 2010 (Word/Excel) poor performance after switching to a new fileserver

Problem:

We encountered poor performance of our Office 2010 applications after moving to a new fileserver.

After some troubleshooting with Sysinternals Process Monitor we found out that the problem was that MS Word tried to create a AutoRecover document on the old fileserver.

So we dug into the registry and found the key that was causing the problem.
(HKCU\Software\Microsoft\Office\14.0\word\Resiliency\DocumentRecovery\something)

Solution:

Deleting the registry key is the solution!

To solve this problem for our users we created a batchfile and put that in a GPO.

Below the batchfile we used:

REG DELETE HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\word\Resiliency\DocumentRecovery /f
REG DELETE HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\excel\Resiliency\DocumentRecovery /f
REG DELETE HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\powerpoint\Resiliency\DocumentRecovery /f
