Only 50 apps? We have about 1100... Lucky we manage with 1 layer 1 sysprep image for all our hardware. Anyway, we didn't find any major issue with 8.7 sofar, it is a lot better then 8.0, somewhere with 8.5P4 I guess.
We tested Patch 1 the day after it was released (May 26th). A couple of days later one of our IT computers reported a virus and deleted the file. Moments later yet another file, and another. At first we thought we'd been hit. In fact duing an On-Demand Scan, Patch 1 falses reports Windows system files as containing viruses and with our policy set to delete, that's what VS did. At least 4 other organization globally have reported the problem. McAfee has now pulled Patch 1 from their web sites. I would suspect we'll see a Patch 1a shortly.
If anybody has Patch 1, either uninstall or at least avoid an ODS at all costs.
