PUR AuthenticationFailure

izzyforeal · Aug 28, 2025

Hello all, having a strange issue. I created only a local account on my laptop when I set it up. And although I've done it in the past if I logged into my microsoft account on the Microsoft Store, I could still download anything I wanted. So the store was the only place I was logged in with microsoft. Now I am getting a PURAuthentification Error when trying to download anything, So I went to log into my microsoft account on the laptop and the login box flashes for a second and then dissappears so I can't login anywhere on my laptop with microsoft. Any help would be great.

As info I have already done a WSRESET, checked my Time and Region settings and did a Network Reset. All with no success. Thanks in advance for any help you can provide. -Izzy.

please try
settings > accounts > email & accounts
and add your hotmail/outlook email account there.

this should then give access to any Microsoft account including the store
Microsoft seem to want everybody permanently signed in to access anything.

best of luck, Steve ..

Thanks for the response Steve but no luck. The window opens like it's going to let me login and then disappears. Thanks for the response.

Hi,
Do you have UAC disabled?
A second-long flashing sign-in pane usually appears when UAC is disabled.

OAT, Yes I did have it off. I enabled it, restarted but still no luck. Thanks for the response.

A couple of ideas from Copilot for what it's worth:

Fixes you can try:
• Run the Windows Store Apps troubleshooter: Go to Settings > System > Troubleshoot > Other troubleshooters and run the one for Microsoft Store.
• Reset the Store cache: Press Win+R, type wsreset.exe, and hit Enter.

Hello OldMainFramGuy. Thank you for the input but I've tried those fixes without success.

on another device, try going to and logging into https://accounts.microsoft.com
If that fails, use forgot password or use the Microsoft Authenticator app.

6. Enable Microsoft Account Sign-in Assistant
• Open Services ()
• Find Microsoft Account Sign-in Assistant, set it to Automatic, and start the service

Another try from CoPilot

Thank Spunk, already tried and failed. As info to all I created a new admin account in CMD prompt successfully. However, still got the same error at the store.

Downloading Windows 11 Media Creation Tool and reinstalling Windows. Sucks but that's about all I have left in the gun. Thank you all for the assistance.

Press the Windows key +I in Settings, go to System/Recovery/Reset this PC. Choose Keep My Files.
It should reset without loosing any of your files.

Oh ok, cool. I was unaware of that. Thank you Spunk.

Spunk, the reset lets me keep my files but deletes my apps so just reinstalling Windows.

Spunk · Aug 30, 2025

It is just reinstalling Windows, but it keeps your personal files if they are not backed up somewhere else, that is the difference.
It should keep your apps as well, some apps may need to be reinstalled.

Well reinstalling fixed everything!

Congratulations. Thinking back, a friend once had an issue with Microsoft Store on Windows 10; every time he tried to use it he got a non-helpful "Something went wrong" message. I tried all of the remedies but ended up doing a repair install to fix it. Microsoft Store seems a bit fragile at times.

It’s very fickle like my fat exwife.
