corrupt registry

[onelane]

I was removing a person's name in the registry and inadvertently deleted something I shouldn't have. The User Control Panel does not work. When I try to install a program or anything that relates to the User Control Panel, the box appears asking me if I want to make changes. The problem is, The YES button is missing. Need help

Hi @onelane,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If you accidentally deleted an important registry entry and now the User Account Control (UAC) prompt is missing the "YES" button, this indicates that you might have altered or removed critical permissions or settings. To resolve this issue, follow these steps:

Method 1: Restore the Registry from a Backup

If you created a backup of the registry before making changes, you can restore it:

Access Safe Mode:

• Restart your computer and press F8 (or Shift + F8) before the Windows logo appears to access the Advanced Boot Options.
• Select "Safe Mode" and press Enter.

Restore Registry Backup:

• Open the Start menu, type regedit, and press Enter to open the Registry Editor.
• Click File > Import and select your backup file to restore the registry settings.

Method 2: Use System Restore

If you didn't back up the registry but have a system restore point, you can use System Restore to revert to a previous state:

Boot into Safe Mode:

• As mentioned above, restart your computer and press F8 to access the Advanced Boot Options, then select "Safe Mode".

Open System Restore:

• Open the Start menu, type rstrui, and press Enter to open the System Restore utility.
• Follow the on-screen instructions to restore your system to a point before the registry changes were made.

Method 3: Fix Permissions via Command Prompt

If restoring the registry or using System Restore is not an option, you can try fixing permissions using the Command Prompt:

Boot into Safe Mode with Command Prompt:

• Restart your computer and press F8 to access the Advanced Boot Options, then select "Safe Mode with Command Prompt".

Open Command Prompt as Administrator:

• Once in Safe Mode, open the Start menu, type cmd, right-click on Command Prompt, and select "Run as administrator".

I hope this helps.

Take care and have a good day.
