It seems you're experiencing an issue with your user profile on your Dell OptiPlex 7060 after a Windows update or unexpected restart. It's good that you've tried some troubleshooting steps, but it appears that the issue persists.
Here are a few more steps you can try to resolve the problem:
1. Create a New User Account:
- Press the Windows key + R to open the Run dialog box.
- Type "netplwiz" and hit Enter to open the User Accounts window.
- Click on "Add..." and follow the prompts to create a new user account.
- Make sure to set it as an administrator account.
- Restart your computer and log in with the newly created account.
2. Copy Files to the New User Account:
- Open File Explorer and navigate to the C:\Users folder.
- Locate your old user profile folder and the new profile folder you just created.
- Copy all files, folders, and subfolders from your old profile to the new one, excluding the following files: Ntuser.dat, Ntuser.dat.log, Ntuser.ini.
- Once the files are copied, restart your computer and log in with the new user account.
3. Consider Restoring from a System Restore Point:
- If the issue persists after creating a new user account, you can try restoring your computer to a previous state using a system restore point.
- Press the Windows key + R, type "rstrui" and hit Enter to open the System Restore window.
- Select a restore point dated before the issue occurred and follow the prompts to restore your computer.
- Keep in mind that this will revert your system settings and installed programs to a previous state.
If none of these steps resolve the issue, you may need to contact Dell support or consider performing a clean Windows installation. Remember to back up your important files before trying any major changes to your system.
Hope this helps!
