UPDATE: As of Friday, October 5, 2018, Microsoft has now pulled Windows 10 1809 due to an overwhelming amount of reported bugs. See: Microsoft Removes Buggy Windows 10 1809 Upgrade
In a way, I guess you could say that Microsoft is delivering its next big FU (Feature Update) to customers this month.
As we reported yesterday, there’s a known bug where upgrading to Windows 10 1809 (October Update) will delete user files. Seriously.
There’s been much speculation about what’s causing this, and at least one culprit has been located. This particular issue is a GPO/registry value at:
Computer Configuration/Administrative Templates/System/User Profiles/Delete user profiles older than a specified number of days on system restart
This registry key needs to be Disabled or set to Not Configured before upgrading to Windows 10 1809.
If you’ve taken the upgrade plunge without addressing this issue, check out a post by Woody Leonard. He’s located a third-party application that should be able to retrieve your lost files.
Microsoft has yet to admit to this issue. It will be interesting to see what they say.
Bottom line here, though, is to wait for Microsoft to come clean and issue a fix. For now… it’s best to just stay clear away from this upgrade.
