Windows 10 password problems: Microsoft says it’s fixing bad ‘password amnesia’ bug

Microsoft says it’s a workaround and is creating a cure for a bug in Windows 10 variant 2004 that makes PCs forget that the username and passwords for installed apps, including Outlook.
Microsoft has posted a brand new support note about Outlook and other programs forgetting passwords following users installed Windows 10 version 2004, aka the May 2020 Update.

That build was released in preview in April, and consumers have been complaining ever since roughly Windows 10 apparatus being not able to remember credentials following the upgrade. Microsoft points to a user complaint on its Replies forum from April.

An owner of a Microsoft Surface Guru 5 said after updating to Windows 10 version 2004 the device suffered from”system-wide password amnesia”, making what seems like login hell to get your user.

“Each time I log in, I must sign in to the OneDrive private and OneDrive company,” Windows 10 user TMagritte wrote.

Other symptoms include Outlook persistently requesting the user to log in to Office 365 every couple of hours; Adobe Acrobat constantly nagging for Adobe logins every time a PDF is loaded, and the Windows 10 Settings program periodically requiring users to repair their Windows Insider account settings by reauthenticating with Windows 10 Hello biometric authentication.

Additionally, the LastPass password supervisor extension in Firefox keeps requesting users to enter their password despite being configured to only require a fingerprint.

Borncity reported to the problem in August after an account by an individual who had upgraded to Windows 10 variant 2004 in June and discovered that Credential Manager has been broken.

“It’s driving me crazy,” the Windows 10 user wrote on Windows Six Newsgroups.

“Is anyone else having problems with savings passwords? I’m using Edge Chromium. They were OK before the 2004 update. I kept thinking I’m doing something wrong.

“I’ve checked Edge settings, and although I just logged on for the umpteenth time to this particular forum I see that it doesn’t reveal as saved from Edge passwords. I do not have this optioned to clean passwords on exit, and I am checking to save password at the logins.

“Should Windows qualifications start-up be starting automatically? Optioned Credentials startup to automobile, and it looks as though my problem is cured. It’s driving me crazy. Seems like it worked for one restart, now it not saving passwords “

Microsoft states the problem occurs when some Windows 10 Task Scheduler Tasks are”configured in a certain way.” To avoid the password amnesia problem, Microsoft recommends disabling those jobs in Task Scheduler. 1 task that appears to cause the issue is your HP Customer involvement utility job, Microsoft notes, pointing to the help from a volunteer moderator on the Replies forum.

Feb BleepingComputer, Google safety researcher Tavis Ormandy in September was so annoyed with the Windows 10 2004 bug he spent a whole weekend debugging the matter. He eventually found the root cause of the insect and has been in discussions with Microsoft engineers to get the problem resolved.

“I have been experiencing a really bad Windows 10 insect because the 2004 upgrade,” wrote Ormandy.

“I got so annoyed I spent my weekend debugging it. A particular type of scheduled task may break CryptUnprotectData(). If you’ve seen programs losing the country, event id 8198, or NTE_BAD_KEY_STATE, might be this.

“The bug is the RPC [that] UBPM (Unified Background Process Manager) uses to create the S4U (Services For User) Token for task scheduler will sometimes clobber your stored credentials in LSASS. That is used to derive your own DPAPI User Encryption Key, therefore that it changes and no longer functions .”

Until Microsoft delivers a fix, its recommended workaround involves right-clicking the Windows 10 Start Button and selecting Windows PowerShell (Admin).

Microsoft then recommends:

Then visit Windows Task Scheduler and disable any tasks you found from the preceding command.

Microsoft notes that consumers may have to re-enter missing passwords one more time until it’s saved again.
