How to run Registry (.REG) file as administrator?

Windows Registry is a hierarchical database. It holds information related to settings, options, and other values for software and hardware on your system. Windows allows users to make changes in the Registry using a REG file. If the user follows a standard format, one can run Registry (.REG) File as administrator and make the changes.

Best Practices and Precautions before running a REG File

Before you go ahead and run a registry file, here are some practices and precautions to keep in mind:

Back up the Registry

As mentioned earlier, Windows Registry is a hierarchical database with configuration details for many Windows application settings. So whenever you change the Windows registry, any wrong configuration can lead to several issues.

To take a Windows Registry backup, here is what you have to do:

Press Windows Key + R to launch RUN.
Type regedit and press Enter key.
Go to File> Export.
Choose a file location, name your backup file, and save it.
To restore the backup, select the Import option under the File menu.

Review the contents of the Registry file

Before you run any Windows registry file, make sure to prevent the contents and ensure that there is nothing wrong.

Reviewing a registry file isn’t complicated; you can right-click the reg file and open it using Notepad.

Just run a quick look over the File and see what it says. If you find anything suspicious, a quick search will help you out.

Run Antivirus scan

Thirdly, you must run a quick antivirus for potential security threats, especially if you downloaded any registry settings online. While registry files cannot install malware, they can be quarantined if malware or viruses pose as REG files.

@echo off

reg import "C:\path\to\examplefile2.reg"

echo Registry files imported successfully.

How do I create a .reg file?

The format of a REG file is relatively straightforward. It consists of a set of registry keys and corresponding values identified by a path. Here’s an example of a REG file:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Example]
"Setting1"="Value1"
"Setting2"=dword:00000008
"Setting3"=hex:12,29,35,46

The file begins with a header line specifying the version of the registry editor. The most common version is “Version 5.00”.

In the example above, [HKEY_CURRENT_USER\Software\Example] specifies an ” Example ” key under the “Software” key of the current user’s hive.
