So some more bewildering feedback for MSFT -- although something tells me their silence is a key indicator they are conveniently ignoring and hoping this mess quickly becomes yesterday's news...
As I reported earlier, wiht my folder redirection in play a non-profile (special) folder called "Desktop" had all its contents deleted after upgrading to 1809. Yes, I had a backup, so a quick copy from my imaged drive had me running for almost a week on 1809 in all it's spendor :-|
Low and behold, I just discovered my SIP softphone (off of my Corporate Genesys platform) no longer functions on v1809 (there are .NET dependencies so guessing that's broken (again) wiht this new build -- similar to the Fall Creator build of 2017. Build 1803 had this working fine so after some testing in the lab, sure enough, 1809 fails, but roll an upgraded PC back to 1803 and all is well with the SIP softphone.
Here's where it gets interesting... When I upgraded, I lost all files in my C:\users\rcurtis\desktop folder -- again, not my 'real' desktop and not profile based, nor is it a 'special folder', just a folder I created and called it "Desktop". After I rolled back to 1803, low and behold, what was there under 1809 is, again, gone. Understandable since there was no such files in windows.old, but again, why is MSFT touching personal files -- shame on you MS!!
