Aug 31st Windows 10 Updating Erases Entire Cache

[RawPower]

Lost all my filled up L2 Cache of 190GBs or so after latest Windows 10 Update on current 1607 Build. Had to Reset Network to as internet online was killed too. FYI.... back to Verifying Game Caches on my Steam Games to Preload Caches again. UGH. But, best update I always say.

When Windows runs major upgrade, it will rebuild all existing drivers, including volumes and PrimoCache drivers. This erases the stored cache tasks and cache information. We will look for a solution for this problem.

I found it also removed drives assigned to cache tasks. Wasn't surprised, and they were easily re-added.
