Windows Search is one of the nastiest pieces of software for use in VDI, especially floating pools. The index is created a on a per-machine basis so when a user moves to a new machine, the index needs to run again. The index consumes disk space, hammers DiskIO, and needs to be run every time the user moves machine.
Uninstalling it resulted in Office 2010 Protected modes doing very strage things and reporting files as corrupt.
I have disabled completely via GPO, and hope not to ever have to use it again.
All in my humble opinion of course! ![]()
