Windows 10: Windows 11 system does not grant access even when correct credentials are supplied

I have a Win 10 system and am trying to connect it to my new Win 11 laptop. The Winn 11 box can see the Win 10 box, and can gain access to all appropriate shares. Jolly Good!The Win 10 box can see the Win 11 system, but EVEN WHEN I CHANGE THE CREDENTIALS ON BOTH SYSTEMS AND RESTART, the Win 11 system refuses to allow the Win 10 system to access it.The support suggestions are laughable and seem to be variations on "Destroy your system and see if this helps" Remove all credentials, turn-off password protected security, and the like.If I have identical User Name/Password combinations on both sys

Scheduled tasks run with elevated privileges can't access stored Windows credentials

It seems that after Creators update scheduled tasks run with elevated privileges ('run with highest privileges' option) can't access stored Windows credentials. Is that a bug or an intentional change and is there a recommended workaround?

Here's one way to reproduce the behaviour:

• Start Credential Manger and add some Windows share credentials.
• In a console window type 'cmdkey /list', which should list the added credentials
• Create a task in a task manager:
  • Trigger: on user logon
  • Action: run cmd.exe
  • Tick the 'run with highest privileges' option
• Reboot the machine and log in
• In the console window (let's call it 'console 1') opened from the scheduled task type 'cmdkey /list'. This most likely won't display the credentials added in step 1 and properly listed in step 2. ->
  This looks like a bug
• Now, without closing 'console 1' open another console window as an administrator (let's call it 'console 2') and type 'cmdkey /list'. This will properly list credentials added in step 1.
• Switch to 'console 1' and type 'cmdkey /list' again. This time the credentials are listed properly, unlike in step 5. It looks like an access to Windows credentials was somehow 'unlocked' by step 6.

Windows 10 not accepting Microsoft Account as Network Credentials

Help, please?

I have three computers on my home network, all with Windows 10. They all could access each other's files through the network after entering my Microsoft Account as Network Credentials.

I replaced the hard drive in my laptop and installed Windows 10 again. Now it cannot access the other two computers, nor can they access the laptop. When I enter my Microsoft Account info in Network Credentials, it says "The user name or password is incorrect".

What I have done:

1. Double-checked that I am using the correct password with my Microsoft Account.
   
2. Rebooted router.
   
3. Connected laptop to network with a network cable.
   
4. Tried everything mentioned on Fix Enter network credentials error on Windows 11/10, on the laptop and my main desktop without success.
   
5. Created a local account on the laptop with a username & password, and I am able to access the files on the laptop from the desktop using that username & password as network credentials, but using my Microsoft Account as network credentials still will not work.
   

None of my computers can be updated to Windows 11, so please don't suggest that.
