Windows 10: Help! - Seem to have lost Administrator access to laptop

Hi - hoping someone can help here. I bought a retiring laptop from my company for my son to use. The IT team at my company wiped everything off, but it came with Windows 10 on it, otherwise it was clean.I subscribe to Office 365 and share with my family. I set up my son's laptop with me as the Administrator and him as a Standard User. We both had passwords, but also PINs to log in. This worked fine for at least a year - in general, after initial set, I haven't needed to log back in for a long time.He needed some software changes recently, so I tried to log in as Admin to make the updates.

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

 

Lost My Administrator Password

To which "this" are you referring?
- If you are following the tutorial Bree suggested in the very first reply to your question then what you need to do at each step is explained in detail. So which step are you at?
- If you are following a different procedure then state what it is and which step you are at. If, for example, you are trying to manually enable the Built-In Admin as suggested in post #11 then that account has no password.
