778322 - Remove the prefetch deleted registry key from machines that contain it

Status: VERIFIED FIXED

(Core :: Widget: Win32, defect)

Description

[Jason Smith [:jsmith]]

We are no longer clearing prefetch files anymore, but the registry key still exists in the Windows registry. We should clean up after ourselves and get rid of that registry key if we detect it.

I'm not disputing the validity of this task, but just wanted to add a note that the uninstaller will get rid of it.

Comment 2

[Brian R. Bondy [:bbondy]]

Actually I was wrong in Comment 1, I tested this out and since the Attempted reg value needs to exist which is alongside the ffdeletedprefetch registry value, the whole key folder isn't removed.

Attachment: Patch v1.

This is just a simple cleanup task with a reg value that is no longer used.
The service installer is run on each update so it will get rid of the reg key on the next update.  It's also added to the uninstall section of the maintenance service in case someone doesn't get an update but uninstalls instead.
