Systemwide password amnesia (v2004 build 19041.173)

I have a Surface Pro 5 with a Windows Hello camera that wasn't working and I wasn't able to fix it. Looked like I'd need to do a reset to fix the drivers, so instead I decided to give 2004 a try, hoping the update would refresh the camera drives. Indeed this worked, but I've been having a lot of problems since the update:

Seems like all sorts of applications and OS features won't remember my username/passwords anymore.

  • Every time I log in I have to sign into both one drive personal and one drive business.
  • Outlook keeps asking me to log into my office365 every few hours.
  • Acrobat keeps asking for my Adobe login every time a load a pdf if I haven't done so in a few hours.
  • Settings periodically makes me fix my insider account configuration by re-authenticating with Hello
  • Lastpass extention in Firefox keeps asking me to enter my password despite being configured to only require a fingeprint (it first asks me for my fingerprint, but then also asks for the password)
  • probably some stuff I can't recall right now.

I wasn't having any of these issues before the update.

I tried following Lastpass's support advice to fix it by reinstalling the extension and resetting several settings but this didn't help.

It's possible these are all individual issues, but since it seems to be an issue with remembering credentials across a variety of applications, I'm suspecting it's a system wide issue and maybe not specific to these applications.

I checked that the credential manager service is running. It was set to manual. I changed it to automatic and rebooted but this didn't seem to help.

Anyone have an idea what could be going on here?

Thanks!

Update 2/8/21

This issue has been fixed by Windows in this Windows 10 update, February 2, 2021—KB4598291 (OS Builds 19041.789 and 19042.789) Preview (microsoft.com).

  • Addresses an issue in which using local Service for User (S4U) affects Data Protection API (DPAPI) credential keys and causes users to sign out unexpectedly.

I am updating the Outlook Known Issue article to reflect the same, Outlook and other apps won't remember password after Windows Updates - Outlook (microsoft.com).

    It's been 24 hours and I am pleased to report that since removing the HP Customer Satisfaction task my system has not had one prompt for passwords.   I consider this issue resolved.   Now I did do all of the previous 8 steps as well prior to identifying the S4U task login and I removed all extraneous accounts on my PC include the MS account.   I am only using a local account now and have the administrator account active.   

    I hope others are able to resolve this as well.   Thanks again to everyone that worked this thread.    I'm checking out now.

    Just want to re-confirm my previous observation:

    Outlook forgets my passwords, the password fields are empty and obviously Outlook cant connect to the servers. After several restarts, it is still the same.

    However, putting the machine to sleep and then waking it up after few hours... and the passwords are back on and Outlook starts downloading perfectly.

    So the passwords are definitely NOT forgotten. It is very strange indeed. The system somehow is recovering by itself.

    The way that the PowerShell command is written below, it list tasks with a filter that makes it finds those who are susceptible to call a certain windows API.  (LogonType = "S4U"). This logon type triggers the windows bug. This is a search for any tasks that could perform this type of logon. So if the command list other tasks than HP's, they also have to be either disabled, deleted, or changed to another logon type (one suggested is "run only when user is logged on").  This is the choice I made.

    Is it possible that something else that schedule tasks may perform this type of operations? I don't know.  If the workaround fail, this may explain it.

    • Get-ScheduledTask | foreach { If ((xml).GetElementsByTagName("LogonType").'#text' -eq*"S4U"**) { $_.TaskName } }*
