## Patch bundle restoration

Earlier I was having trouble trying to get one of the patch bundles (Discover Applicable Updates Windows-x86_64-en-2008sp2) to run on one of our servers. Turns out the actual problem was unrelated to the bundle itself, but I had already made an alteration that seems to have broken it.

The change I made was removing the "Delete Signature Files" Action under the "Install" tab. Change was incremented, etc. However whenever I try to go back in to re-add this action, I click "Ok" and it disappears.

I have two questions. If I delete the bundle can it be restored? If so how? Or, can I restore the change I made? If so, how?
