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 works, but is it safe? I do not like to play in the guts of the crypto API or Data Protection API. Where does this workaround comes from?

Thanks so much. Yes, you are right, i didn't check to show system files, so indeed, there are many files in the <SID> folder. I tried your appl and it showed OK result and 4 green OKs. So this is not my problem obviously... Still, something very weird is going on here. I hope it will be soon rectified. I found HP Smart app on my computer, which i uninstalled, but it had seemingly no scheduled task entries. I am sure though that the problem will come back, its like the covid19 nobody knows what it is exactly... P.S. 5 minutes later..... the problem stroke again. Outlook stopped downloading. After restarting it (restarting Outlook), all password fields are empty and of course no connection with the server. Closed outlook. Pressed the sleep button (plain sleep, no hibernation, no fast boot or anything), then pressing it again to wake the laptop, fired outlook and voila.... Outlook is up and running, and the passwords are all in their fields. ANY IDEAS? Somebody can replicate that?

You can't see the files because they're marked as system and hidden. Navigate into the folder using the command line and type dir /A otherwise the directory will appear empty.
