How To Restore the Registry in Windows 7

 usually only takes a few minutes:

1 - Locate the Registration File you exported before making your changes to the Windows 7 Registry.
2 - Double-click on the REG file to open it.
- Next you'll be prompted with a message in a Registry Editor window:

" Adding information can unintentionally change or delete values and cause components to stop working correctly. If you do not trust the source of this information in [REG file location], do not add it to the registry. Are you sure you want to continue?"

Important: This isn't a message to be taken lightly. If you're importing a REG file that you did not export or one you downloaded from a source you can't trust, be aware that you could cause considerable damage to Windows 7, depending on the registry keys being changed.

3 - Click the Yes button.

Assuming the registry key(s) import was successful, you should receive the following message in a Registry Editor window:

The keys and values contained in [REG file location] have been successfully added to the registry.

4-Click the OK button in this window.
The registry keys contained in the REG file have now been restored to the Windows 7 Registry. If you know where the registry keys were located, you can open Registry Editor and verify that the changes were made as you expected.

5-Restart your computer.

What Is The Windows Registry?

The Windows registry is a database which stores settings and options for the operating system for Microsoft Windows 32-bit versions, 64-bit versions and Windows Mobile.

It contains information and settings for all the hardware, software, users, and preferences of the PC. Whenever a user makes changes to “Control Panel” settings, or file associations, system policies, or installed software, the changes are reflected and stored in the registry.

The registry is actually a big file where a lot of setting can be stored.

This file has been around quite a while and has had different names.

The first windows version that used the windows registry to store settings was windows 3.11 and the registry in that version of windows was called Reg.dat.

In Windows 95 & 98 the registry files are named User.dat and System.dat and are stored in the Windows directory.

Windows ME called the registry files, Classes.dat, User.dat, and System.dat and stored them in the Windows directory.

Finally the newest versions of windows like, Windows NT, 2000, 2003, & XP stores the registry files like this,

The Registry files are stored in %SystemRoot%System32Config:
