Forgot the outlook mail adress - locked out of C-drive

Hi all.

 

This notebook has been out of use for several years. I forgot the password for mye outlook mail account. I'm still able to login to Windows (10). However I am locked out of the C-drive. The notebook is too old to install Windows 11. I'm wondering what to do to get admin rights back?

I used some German app several years ago to get rid of the Microsoft Office packaged as I prefer to use Apache OpenOffice. The software made some Microsoft apps stop working as they should. The Microsoft Store (for apps) has been out of order since December 2024.

Somehow I managed to install some apps through the browser, however this is cumbersome. I'm also missing important drivers and have trouble finding the right tool or app for updating drivers. I used to be a power user back when Windows 2000 was the newest Windows.

 

When I try to open the Device Manager from Windows Explorer I just get an error message, see the attachment. What to do?

 

All the best from Denmark

  • I have admin rights, should have had at least. PowerShell stopped working and I'm left with the console. Probably got quite a bit of unconventional code on the system.

    Guess I'll have to migrate to Linux instead. The Windows Update is failing, and personal computers are no longer personal. It's a bit of a hassle to be honest.

    1. Recover Microsoft account: 
    Visit Microsoft account recovery page 
    Select "I forgot my password" 
    Verify your identity by alternate email/mobile phone number 
    Unlock local account (administrator privilege is required): 
    2. Log in with other administrator account 
    Go to "Settings > Accounts > Family and Other Users" 
    Reset password of the target account 
    3. Recover access to the C Disk 
    Temporarily obtain privileges: 
    Right-click C Disk > Properties > Security Click "Advanced" > Change Owner Create new account to transfer data: Settings > Accounts > Add New Local Account Copy data with the new account after logging in. Properties > Security 
    Click "Advanced" > Change Owner 
    Enter the current user name > check "Replace subcontainer permissions" 
    4. Create a new account to transfer data: 
    Settings > Accounts > Add new local account 
    Copy important files after logging in with the new account 
    5. Preventive Measures 
     Bind at least two authentication methods (cell phone + alternate email address) 
    Regularly back up the BitLocker Recovery Key Enable the System Restore point
