Microsoft has addressed a known issue impacting multiple Windows 10 apps and causing them to forget users' passwords after upgrading devices to certain Windows 10, version 2004 builds.
The issue was resolved in the KB4598291 release preview cumulative update for all editions of Windows 10 and Windows Server versions 2004 and 20H2. This update also comes with fixes for device deactivation issues and freezing problems while playing games full-screen.
Due to a bug in the RPC UBPM, Windows 10 would forget passwords by removing saved credentials in the Local Security Authority Subsystem Service.
Microsoft first acknowledged the issue causing Outlook and other apps to forget user passwords in a document published on its support website in November 2020.
"This issue occurs when some Windows 10 Task Scheduler Tasks are configured in a certain way," Microsoft said.
In the Windows 10 Search box, type Task Scheduler, and then open the Task Scheduler app.
