Windows 10: Don't know how to set new Administrator

I got my ex colleague laptop. He has Administrator rights and OneDrive account as default. I tried to Add someone, but have to Sign in into Microsoft account. The only option is my ex colleague account. How to change Administrator rights without login to Administrator? Should I contact my ex college to Add someone and then as a new administrator I could remove old administrator.

Settings can't be opened using the built-in administrator account


Hello,
Unfortunately I have the same issue as Dabz from upgrading win7 to win10.
I've tried opening settings using all the suggested methods and it will not load using my account with Administrator access nor the built-in Administrator profile. I also tried other methods not listed such as using Run. Control panel is just a stepping stone to add users in Settings.
I'm also having explorer.exe issues, which I believe is preventing Settings from loading.
Using cmd (Admin) I successfully created a new user profile [and granted admin access also using cmd (Admin)], however win10 will not allow this account to log on. win10 does not list this new user within control panel but it does in the start menu. win10 will not allow to log in or switch to the new account via the start menu either.
I can access settings in Safe Mode but this will not allow me to create a new account.
Any help/suggestions will be greatly appreciated.
Cheers
