How to keep your registry clean

Keeping your registry clean is a very important part of computer maintenance, because it ensures that your computer stays fast and stable.

What is the registry and why is it there?

The registry is a database that stores all Windows options and settings. It contains all the data for all hardware, operating system software, all other applications, and all user settings (user profiles, installed software, the type of documents the users create, etc). All that makes the registry the most vital, but also the most vulnerable part of a Windows computer.

Programs access the registry thousands of times per second and new entries are created whenever you install new software or hardware. All this makes the registry a very complicated database. That’s why it’s so important to keep the registry clean and well looked after.

How do registry errors affect computer performance?

When you uninstall a program, its registry entries get deleted as well. That’s the case with most applications. However, some programs leave a lot of rubbish behind. That clutters the registry with obsolete entries that point to non-existent software. Such invalid entries accumulate over time. As a result, Windows needs a lot more time to access the registry and your computer takes longer to respond. Not to mention viruses that love to attack the registry and modify it to make your computer vulnerable and unstable.

That’s why it’s so important to keep the Windows registry junk-free and fix errors.

How to clean the registry?

These days keeping your registry clean is a lot easier than in the past when you had to open the Registry Editor (Click on StartRun – type regedit and hit Enter) and find invalid and corrupted entries. That required extensive computer knowledge and was very dangerous, because one entry deleted by mistake could make your computer unbootable.

Of course, it’s still possible to use Regedit, but it’s a lot safer and easier to use one of the free registry cleaners available on the market.
Before you download a registry cleaner make sure that:

  • it is developed by a trusted company;
  • it backs up the registry before deleting any entries;
  • the registry cleaner is not promising to fix every possible error on your computer. A lot of errors need specific fixes that are not related to the registry.

Good examples of reliable free registry cleaners are Auslogics Registry Cleaner and CCleaner. Both come from reputable developers, are very easy to use, and offer you to backup the registry, so that you can undo any changes if there are any problems.

Registry Cleaner is a great tool for repairing your Windows registry and dealing with stability issues, but there may be problems on your PC that are caused by other factors, such as junk accumulations, incorrect system or internet settings and similar. Auslogics BoostSpeed is a powerful optimizer that lets you clean out junk files, resolve registry issues, eliminate slowdown causes, clear privacy traces to protect your confidential data and so much more.

    Thank you Liz Cornwell for the effort of sharing this helpful information to us. Many of us are actually having problems with our PC and we need this. Keeping a registry clean can be a somewhat difficult task especially when done manually which is why even experienced computer users opt to keep their registry clean through the use of software specifically designed for this purpose. If you keep your registry clean of conflicts and errors, then your system’s performance will be good.

    My laptop had a heavy problem in the registry because my frequent download of new programs that leave entries when uninstalled. Also for the daily web surfing of websites that are new and unknown.

    There are many programs that look like free registry cleaners but are really blackmailling malware under the appearance of authentic free programs. I found that these get my private data and online interests and purchases information. These malwares are difficult to uninstall and leave the registry in very bad shape.
    AUSLOGICS is a serious enterprise that helps the user to repair their personal computer operation process in the registry, defragmention, and Disk Health and leaves it neat!
