Windows 10: ERROR 87 Credential Manager Vault Svc Could not start

here is my post on the microsoft community, which is not helpful at all.
ERROR 87 Credential Manager Vault Svc Could not start - Microsoft Community

i think this is the root cause of the chains of problems i am having all of the sudden: my mail app not syncing emails, Pin for login suddenly stopped working;can only sign in with password, app store cant download anything, nvidia control panel stopped working, windows update not working, windows repeatedly notify me "you need to fix your Microsoft account", windows remote desktop doesn't work, itunes will not install, virtual box will not install, the list goes on.

things i have tried: safe mode, sfc scan, DSIM restore health, diagnostic startup(which ended up killing the login screen and i have no way of logging in), restore windows image(to a different build, which did not work. andUNFORTUNATELY, windows did not save any system restore before the problem began, check vault Svc parameter in registry.















god damit microsft, i dont want to reinstall windows again! please help guys*cry

ERROR 87 Credential Manager Vault Svc Could not start

Hi,

To help you resolve your concern, kindly download and run the Windows 10 app
troubleshooter. If this issue still persist, let's try to run the System File Checker tool. System File Checker is a utility available in Windows 10 that checks for system file corruption. It's recommended for advanced users. To do that
kindly follow the steps below:

• Click Start or press Windows key and enter
  Command Prompt.
  
• Since the right-click options will not work, instead of pressing the
  Enter key, press hold Shift and Ctrl key then press
  Enter. This command will run the Command Prompt as administrator.
  
• Input sfc /scannow and press Enter.
  
  Note: there is a space between the sfc and /.

Let us know if there's anything else we can do to help.

i think this is related to my mail app not syncing emails and Pin for login not working, app store cant download anything, nvidia control panel stopped working, windows update not working, the list goes on

 

Credentials Manager should be set to Manual not Automatic. The service should only run when called upon by another service. Also IF RPC is disabled Credentials Manager will not run.

 

Well, RPC is running, i just checked, and credential manger doesn't start in any start mode.

 

I would say it is a problem with your Microsoft Account. Can you log into it from this link:

Microsoft account | Home

 

If you have trouble with log in look at this link:

no problem logging in at all sir

 

If log on was successful that way then my best guess is that the Credentials Manager is corrupted. I suspect you have already tried the Windows System File Checker to no avail. In these cases it has become my practice to do a Windows Refresh install which will leave all of your files in place yet rewrite the Windows system files.

 

of course we all know that is a solution, but if you are like me, who installed 300 programs and have lots of customizations, refreshing/reinstalling is not nearly a practical solution. (so far, fresh windows installations have not last me more than a few years before i f*ck it up, lmao*Sad)

 

Not talking about a clean install. What I am suggesting is what was once known as an In Place Upgrade, now called a Refresh or Reset. Does not remove any programs, user files, nothing. Just rewrites the Windows System files.

Download the tool from this link and try again

thank you Railtech, i download a ISO on the pirate bay and it worked, windows is not corrupted again!
