Windows 10: Error 0xCFFFFF828 - Can't sign in on Windows apps

I changed my password last night and wake up to my Xbox App and Windows Store apps giving me this error and refusing to download anything. No idea how to fix this. I tried signing out and back in hoping it would just let me input my new password. I even selected "Sign in with a different account" but still, after typing my new password in, it hasn't budged.

App Store sign-in error, 0xD000000D

Hi Suzanne,

There's a possibility that you are currently signed in on your computer using your local account. For us to sort this out, we suggest that you sign in with your Microsoft account instead. Follow these steps:

• Open Settings > Accounts > Your email and accounts.
• Select Sign in with a Microsoft account instead.
• Follow the on-screen instructions.

Once signed in with your Microsoft account on your computer, try signing into the Windows Store app.

Update us with the result.

Regards.

 

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.

 

Windows 10 Xbox App Sign in error (0x409) 0x80070005

Hi,

Corrupted profile data, an outdated version of the app, and software conflicts that occur when signing in are some of the factors that we have to take into consideration when troubleshooting issues with signing in to the Xbox app on Windows 10. Let's isolate
your concern by answering the following questions:

• Have you made any changes to your device or to your Xbox account before encountering this issue?
• Are you using the same Microsoft account to sign in to the Xbox app and your Windows 10 PC?
• Are you using an administrator user profile?
• Have you tried signing in to other built-in Windows 10 apps like the Store app to check if the same issue occurs?

Meanwhile, we suggest signing in to a different user profile. This can help determine if this is due to corrupted user data. Here are the steps:

• Press the Windows button on your device or keyboard, or select the
  Windows icon from the bottom-left corner of the main screen.
• Select your account name from the top-left corner of the menu, and then select
  Switch account.
• Sign in with an account other than the one you were using.
• Sign in to the Xbox app and check if the same issue occurs.
