How to Enable Regedit

Disable any third-party antivirus programs. Third-party antivirus programs—that is, any antivirus program that isn't Windows Defender—can cause several different problems with your computer. Because of this, disable all antivirus protection that isn't Windows Defender before continuing.

Open Start . Click the Windows logo in the bottom-left corner of the screen.

Type windows defender security center into Start. This will search your computer for the Windows Defender application.

1. On some versions of Windows, this may show up simply as Windows Defender instead.

Click Windows Defender Security Center. It's a white shield on a grey background. You'll see it at the top of the Start window.

Click the shield icon. This icon is in the upper-left corner of the Windows Defender page.

1. When expanded, this option is called Virus & threat protection.

Click Advanced scan. It's a link below the Quick scan button in the middle of the page.

1. On some versions of Windows Defender, click the Home tab instead as there is no Advanced Scan section.

Make sure "Full scan" is checked. Click the circle to the left of "Full scan" at the top of the page if it isn't already filled in.

Click Scan now. It's in the middle of the page. Windows Defender will start scanning your computer for malicious software that might be preventing Registry access.

Wait for the scan to complete. If anything malicious turns up during the scan, Windows Defender will alert you and give you the option of removing the dangerous items.

1. If this scan doesn't find anything, repeat the scan with "Windows Defender Offline scan" checked instead of "Full scan" checked.

Try to open Registry Editor. Once the scan completes, open Start, type in regedit, and press ↵ Enter. If the Registry Editor still doesn't open, you'll need to try a different method.

1. You may need to restart your computer before you can access Registry Editor after the scan.

Open Start . Click the Windows logo in the bottom-left corner of the screen.

Type command prompt into Start. This will bring up the Command Prompt icon in the Start menu.

Right-click Command Prompt. It's at the top of the Start window. A drop-down menu will appear.

1. If your trackpad doesn't have a right mouse button, use two fingers to tap the trackpad instead.

Click Run as administrator. It's an option in the drop-down menu.

1. If you aren't an administrator on this computer, you won't be able to complete this method.

Click Yes when prompted. Doing so will open Command Prompt in Administrator mode.

Enter the Registry refresh command. Type reg add "HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem" /t Reg_dword /v DisableRegistryTools /f /d 0 into Command Prompt, then press ↵ Enter.

Close Command Prompt. Your command should have re-enabled the Registry Editor.

Try to open Registry Editor. Open Start, type in regedit, and press ↵ Enter. If the Registry Editor doesn't open, proceed to the next step.

Restart your computer. Open Start, click the Power icon , and click Restart. Once your computer finishes restarting, you can try opening Registry Editor again.

1. If Registry Editor still won't open, you may be able to use a script to force it to open.

Open Start . Click the Windows logo in the bottom-left corner of the screen.

Type group policy editor into Start. This will search your computer for the Group Policy Editor program.

Click the Group Policy Editor icon. It's at the top of the Start menu. Group Policy Editor will open.

1. On some versions of Windows it may read Edit group policy instead.

Double-click User Configuration. Doing so will expand this item to display the folders below it.

1. Skip this step if User Configuration is already expanded.
2. If you don't see this option, first double-click the Local Computer Policy item at the top of the sidebar.

Click Administrative Templates. This folder is near the bottom of the User Configuration list of folders.

Double-click the System folder. It's on the right side of the Group Policy Editor window.

Click Apply, then click OK. These are both at the bottom of the window. Doing so should re-enable Registry Editor on your computer.

Try to open Registry Editor. Open Start, type in regedit, and press ↵ Enter. If Registry Editor opens, you have successfully bypassed the Group Policy Editor restrictions.

WSHShell.RegWrite p, n, itemtype
Mybox = MsgBox(jobfunc & disab & vbCR & mustboot, 4096, t)
