Hi DeliSlt70,
As far as I'm concerned, it may related with the account you logon the computer, which account do you use, common user account or Admin account?
If you are the Admin of the computer, then please open mmc, add local user and group snap-in, in users, you may see all the accounts for this computer, check if Admin account is disabled, if yes, enable it and use Admin account to login and do those operations.
Best Regards,
Anne
