Thank you for that information.

Have you tried changing your account status from Standard to Administrator?
If not, you can follow the steps below:
1. Press Windows Key + Q, type user accounts and click on the result.
Then select your User Account > Click Manage another account.
In the following window, click Add a user account option.
2. Now we have to create a local account user. So after clicking Add
an account, click Sign in without a Microsoft account (Not recommended), then click Local account. Fill the details on the screen so appeared for adding local
account. Click Finish when done.
3. Press Windows
Key + Q and type cmd, for the search results, click Command Prompt. Type the following command and hit Enter key:
shutdown /r /o
4. The previous step will result your system
to boot into Safe Mode. After getting into Safe Mode, press Windows Key + Q, type user accounts, and
pick the same from results so appear. You would have now two accounts on your system; first your issued admin account and second the local account which you’ve created in step 2. Select local account.
Now
click Change the account type link in following window:
Moving on, change the account status from Standard to Administrator.
Click Change Account Type.Moving on, change the account status from Standard to Administrator.
Click Change Account Type.
In this way, the new local account we’ve created has been changed to Administrator. Now you can restart you machine and log into this account with administrator rights. Since you have administrative privileges now; so you can backup your documents from the
old administrator account.
Finally, delete the old admin account and switch to Microsoft account to synchronize your settings with new administrative account. Your system will now act normally with full admin rights in your hand.
Additional thoughts by Anand Khanse, MVP, Admin:
- Run your antivirus software first. Malware is known to sometimes block admin privileges.
- Try using Clean Boot. If this makes the problem go away, see if you can identify the culprit.
- If it does not help, you could boot into Recovery using Windows DVD or the Recovery partition and run System Restore to restore your computer to a prior point.
- In case of domain computers, check with your system administrator, if has applied any new restrictions.
- This policy setting can be used by Domain Administrators to ensure that only select authorized users are allowed to become members of groups like say the Administrators group : Computer Configuration/Windows Settings/Security Settings/Restricted
Groups.
If nothing helps, then you may want to consider a System Restore or Reset option.
Let us know how it goes.
