Registry Defrag

Registry Defrag needs to compact the registry which is only possible during reboot, when no other programs are running and using the registry. This is why Registry Defrag gets scheduled to be started on computer reboot. Please note that the program schedules itself to run only once. It will display a defragmentation report and will not run the next time you restart your PC.

Registry Defrag works in a way that takes any potential problems into account. While the program is running, it is monitored at every stage and is stopped if any potential issues are detected. To ensure the ultimate safety, Auslogics Registry Defrag works on computer reboot only. This helps eliminate the possibility of any problems occurring while defragmenting the registry.

While the names of these software programs may appear similar, there is a difference in their functionality. While Registry Defrag and Registry Cleaner both deal with the Windows registry, the latter identifies and deletes invalid registry entries to prevent application or system malfunctions that may occur when your system or some program attempts to read the data. At the same time, Registry Defrag reduces the size of memory taken up by the Windows Registry, which is meant to speed up interactions with this important database for your system and software.

As for the difference between Registry Defrag and Disk Defrag, it is quite simple. The former defragments your registry while the latter defragments data on your hard drive.

Auslogics Registry Defrag supports the following Windows versions:

• Windows 7 (32-bit and 64-bit)
• Windows 8 (32-bit and 64-bit)
• Windows 8.1 (32-bit and 64-bit)
• Windows 10 (32-bit and 64-bit)
• Windows 11

It does not support Windows 2000, 95, 98, 98SE, ME, XP, or Vista.

There are no Mac or Linux versions.

Registry defragmentation is an often-overlooked way to additionally speed up a Windows computer. Over time, as entries get written to and deleted from the registry, gaps appear in-between, making the registry take up more memory. Defragmentation eliminates the gaps between registry entries, reducing its size and freeing up memory. As a result, your operating system and software will take less time to read registry entries.

Registry defrag is not an operation that has to be performed very often. The recommended frequency may vary depending on how actively you use your computer. Defragmenting your registry about once in 3 to 5 months is a good starting point. Auslogics Registry Defrag analyzes your registry first and lets you know if defragmentation is in order, so you won’t run this operation when it isn’t needed.

With Auslogics Registry Defrag, you don’t need to worry about backing up the registry before running defragmentation. The program first performs registry analysis and shows you the expected speed improvement you can achieve by running the tool. On the same screen, there is an option to create a system restore point before launching the defrag, which is pre-checked by default. Unless you uncheck the box, the program will create a system restore point to allow you to roll back your Windows to the current state if you don’t like something after registry defragmentation completes.

If you were to run registry defragmentation while your Windows is running, the results could be unpredictable and data damage could occur. This is why Auslogics Registry Defrag only performs registry defragmentation on PC reboot, before your operating system loads. You have the option to reboot and run registry defrag immediately, or schedule the defrag for the next system restart. By default, the program creates a system restore point prior to defragmentation, which makes the operation even safer.

Since a system restore point is created prior to registry defragmentation, you can always roll back your Windows to the state it was in before you launched registry defrag in case of any errors. This is an extra safety precaution, as defragmenting the registry with Auslogics Registry Defrag has proven to be an error-free operation in multiple tests.
