Windows 10: Can't login to my Microsoft account in any Windows app, blank gray popup window instantly...

Hello,I've been having this login issue for a few weeks now since a security update in March and I've tried everything...I'm not interested in trivial solutions or repeated suggestions and would LOVE to avoid a Windows reinstall.When I try to login with my personal Microsoft account in any app Xbox, Store, Edge, Office or even in Windows 11 In Accounts > "Add a Microsoft account", I type in my email, click next and then a gray blank popup window appears, then half a second later closes and then nothing happens. No error message, nothing, it just closes almost instantly so I don't e

[Tip] Automatic Login to Windows and Instantly lock the computer.

Problem: You like to leave XYZ program running 24/7, but XYZ program only starts when you log into the computer(XYZ can be whatever program you want). So when automatic updates hit and auto-restart your computer, the XYZ program doesn't start back up. You could not put a password on your user account, so the computer automatically logs onto your user account when it reboots, but that is insecure, and if you have nosy roommates/children/super intelligent monkeys, if there is no password they might get on your computer and find your huge collection of por...legally obtained songs...



Solution: Set Windows to automatically log into a password protected user account, and then instantly lock the computer.*Rockout :rockout: Here's how:

• I'm going to assume you already have your user account password protected. If not, setup a password for your user account now...I'll wait...ok, moving on.
• In the Run dialog type "control userpasswords2" without quotes. Then press OK.
  
  
  
• In the User Accounts window uncheck the box for "Users must enter a password to use this computer." Press OK.
  
  
  
• In the Automatically Log On window enter your username and password. Press OK.
  
  
  
• Open Notepad and type "rundll32.exe user32.dll, LockWorkstation" without quotes.
  
  
  
• Save the text document as lock.bat. Make sure you change Save as type: from *.txt to *.*!
  
  
  
• Drag lock.bat into your Startup folder.
  
  
  

That is it. Now when the computer is rebooted it will automatically log in to your account, load any programs you want started, and lock the computer so a password is still required to use it.*Toast :toast:

A few notes:

• If you change the password for your user account, it will break the auto login. You will have to go back into control userpasswords2 and re-enter your login information.
• This should work with any recent version of Windows, I've tested it back to at least XP. You shouldn't be using anything older than that anyway.
• I've tested this with Win7 and Vista Home Premium and up. It should work on Home Basic and Starter as well, and it should work on XP Home, but I haven't tested this personally. The lower versions of Windows might not have the Control Userpasswords2 ability.
• This works with Server versions of Windows also.

 

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”
