Can't sign into Microsoft account

Good day Anonymous-7904!

Thank you for reaching out. I'm happy to help.

From what you described, when attempting to sign in to your Microsoft account, the sign‑in prompt opens but closes by itself after about 30 seconds, returning you to the previous screen. This behavior might be related to UAC settings, corrupted saved credentials, or a Windows app registration issue. You can try the following steps:

1. Enable User Account Control (UAC)

If UAC is disabled, sign-in dialogs can close automatically.

Search UAC in Start, set it to the default Notify me only when apps try to make changes

Restart the PC, then try signing in again.

2. Clear Saved Credentials

Open Credential Manager, remove any Microsoft or Windows credentials linked to your account, then retry via Settings > Accounts > Your info.

3. Re‑register CloudExperienceHost

Open PowerShell as admin and run:

Get-AppxPackage Microsoft.Windows.CloudExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Restart and test again.

Additional checks:

• Boot once into Safe Mode and try signing in, then restart normally.
• Ensure Windows is fully updated.
• If needed, create a new local user account to test sign‑in behavior.

Please let me know how it goes!
