This killed my ability to access shared drives.
After 71 minutes on the phone to MS Support the fix was to rollback to 10240.
So hooray, I can now access shared drives.
Boo, now I cant open any PDF's on those drives with Adobe Reader.
I can use the MS built in PDF app, but yuck.
I think Adobe Reader updated to DC between the upgrade and the roll back.
Now I cannot run, uninstall or reinstall Adobe Reader.
Adobe XI is listed in Programs, well it was until I used the Microsoft Cleanup Utility.
When I try to install DC it says it is already installed.
When I try to install XI it says there is a newer version already installed.
Yet I can find no trace of the DC version on my PC.
When I try to open a PDF there is an odd looking Adobe option but it does not work.

Any suggestions?
