How to unlink Microsoft account without being logged-in?

Hello,

Last week-end, someone came to me with a peculiar issue: their Windows account was linked to a Microsoft account that somehow no longer exists, preventing them from logging in. From then, the solution appeared simple: transform the account into a local one.

Unfortunately, all the resources I found online presumes that you are logged into the account you want to unlink, which wasn't possible. And unfortunately, you can't unlink said account from an Administrator account either.

Since the computer was brand new and barely touched, I ended up enabling the Administrator account, creating a new local account and deleting the problematic account.

My question is: if the situation was to happen again, but I cannot delete spare to lose data on the locked account, what should I do?

There used to be a program that I've used in the past called ForensiT. We had to do a large domain migration at work due to a merge-and-acquisition and we used this tool. I don't remember exactly how it worked but it helped with allowing the user log in with their new credentials but still have all their old data. I want to say it went through all the files and updated the security and permissions under the user's profile.

Depends on the data you want to save, and how friendly the apps that put it there are to the data being moved.

Assuming the data is all file-based and well behaved, and you're an administrator on the local PC the steps would be something like:

1. Create the new local account and sign in once.
1. Sign out new account and in as admin.
1. Take a copy of the new account's folder in C:\Users
1. Replace that folder's contents with (a copy of) the old account's contents.
1. Drop the new folder's data over the old, replacing any conflicts.
1. Replace the permission for all contents of the new folder.

And, of course:

*Implement a real backup plan for any actually important files. Cloud service folders are ONE copy, and don't count as backups of themselves.

Boot into the drive with a boot drive (if it's encrypted, hopefully you have the key and then you can use a

DART disk), recover the data, then wipe and lay down a fresh OS.

There's other ways to do it, but IMO, it's best to start with a fresh OS (especially if you have to use Windows).
