The registry is a very important part of your Windows operating system.
It contains information about both the hardware and the software on your computer and every time either of those changes the registry should update itself to reflect that.
Unfortunately, however, the registry itself can on occassion become corrupt itself and for that reason it is wise to have a backup. If you have a modern Windows computer then it is likely that your registry will be backed up as part of System Restore. Therefore this guide is for those of you who do not have System Restore turned on for some reason, or if you have a virus that just affects part of the registry by modifying or blocking something within it.
Backing up the Windows registry
1. As ever, you can gain access to the registry in one of two ways.
Firstly, you can click the Start button and then type regedit into the search box (seen above).
Or, alternatively, you can press the Windows button + R and then type regedit into the box, followed by clicking on OK (seen below).
2. Either of those 2 options will lead you to the Registry Editor.
Here you can either backup the entire registry by highlighting Computer as I have done below or you can choose one of the specific branches that appears beneath that.
3. Next, you need to right click and then choose Export from the list of options that appears.
4. This will open a save box like you see below.
Choose a name for your registry backup and then click on the Save button.
5. If you wish to import a previously saved registry backup then that is a simple affair too.
Simply navigate your way back into the registry editor and then click on the File, found at the top left of the window.
From the drop down menu click on Import… and then choose the registry backup that you want to load.
Backing up and restoring the registry is a fairly simple process but if you make mistakes in this area then they can be costly; make sure you know what you are doing before modifying anything in the registry!
