Registry Editor hidden when open

Hi. RRDodge

My name is Anthony, an Independent Advisor trying to help.

In this case, there are two ways to open Registry Editor in Windows 10:

1. In the search box on the taskbar, type regedit. Next, select the first result for Registry Editor (desktop application).

2. Hold down or right-click the Start button and then select Run. Type regedit in the Open: box and select OK.

Now, if for any reason this does not work, in that case you can use the command prompt to open it, these would be the steps to follow:

• Open the Start menu.

• Click on the Windows logo located in the lower left corner of the screen.

• Type command prompt in the Start menu. In this way, the Command Prompt icon will appear in the Start menu.

• Right click on the Command Prompt. This is located at the top of the Start window. When you click on it, a drop-down menu will appear.

• If your trackpad does not have a button for the right click, use two fingers to press it.

• Click on the Run as administrator option. This option is found in the drop-down menu.

• If you do not have administrator rights on the computer, you cannot complete this method.

• Click Yes when prompted. Doing so will open the Command Prompt in administrator mode.

• Enter the registry update command.

Type reg add "HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ System" / t Reg_dword / v DisableRegistryTools / f / d 0 in the Command Prompt and then press ↵ Enter.

• Close the Command Prompt. Now, the command must have reactivated the Registry Editor.

• Try to open Registry Editor. Open the Start menu, type regedit and then press ↵ Enter.

If Registry Editor does not open, go to the next step.

• Restart your computer. Open the Start menu, click on the Start / Off icon and then on Restart.

Once your computer restarts, try again to open Registry Editor.

Best Regards.

cannot open registry editor

Hi,

How are you opening Regedit ? You will have better results if you open it with a Command Prompt (Admin)..

If what you posted is a Registry file that opened with Notepad instead of Regedit, right click on it and select "Open With" and select "Registry Editor" and set it as Default..

Registry files can be opened, edited, and created with notepad, but must be saved as a .reg file to be of any use..

 

System Restore Error 0x800700AA and Task Manager

Thank you for your response. Some of the common symptoms of (0x800700aa) are unfinished installation of Windows application, virus infections, inaccruate registry entries, corrupt system files, incompatible or outdated software or hardware, unfinished uninstalling
of some files, clashes between the automatic update error and the computer, installing of some corrupt or infectious apps or files, etc. In this case, we suggest to run a clean boot on your computer. Kindly follow the steps provided by
Stephanie Sal on this
link.

Regarding about the Task Manager concern. Malware may prevent opening of Task Manager. So you may want to clear your computer junk files and then run a full or deep scan with your antivirus or security software or Microsoft Security Essentials. If you're
done running those tests. We suggest to run DISM and SFC. By doing so, the task will scan for changed or misplaced files. If sfc discovers that a protected file has been overwritten or corrupted, it retrieves the correct version of the file folder, and then
replaces the incorrect file. Kindly follow the steps below to perform the task:

Run DISM and SFC

• Open an Administrator CMD window. If you can’t find a way, use these steps:
  • Press CTRL+Shift+ESC to open Task Manager.
  • Click File > Run New Task.
  • Make sure you have a check mark beside “Create this task with administrative privileges” .
  • Type CMD.
• Type the following commands at the CMD prompt:
  • dism /online /cleanup-image /restorehealth
  • sfc /scannow
• If neither command shows a good result, go to Reset your PC.

If none of the above options work, review the different recovery options available in Windows 10. The
“Keep my files” option should work – Reset your PC > Option > Keep my files.

If you're unwilling to reset the PC, you can try uninstalling the antivirus software, and do an in-place reinstall.
