Everyone can relate to the desire for our computers to be faster and perform at the best of their capabilities all the time. We depend on these devices not only for work, but also for entertainment, and no one likes having to sit around waiting for something they want or need to do.

As such, I know I'm not the only one who's fallen for the idea of using apps to "boost" the performance of my PC. I've used all kinds of Windows 11 apps, including the ever-popular CCleaner and many others, but in reality, these apps rarely do anything to actually improve the performance of your PC. And when they do, they are often things you can do with Windows out of the box, so they end up being more clutter than anything else. You're better off keeping your PC as vanilla as possible.

You can clear your PC's cache without apps

And you shouldn't do it often, anyway

One of the most common features in many of these performance apps is the ability to clear cached files from your PC as a way to save space, and in turn, improve performance. However, the bulk of what these apps do is already handled by Windows just fine. You can use Disk Cleanup, or the modernized tool in the Windows 11 Settings app, to clear thumbnails, cached Windows Update files, and more, whenever you want to. And if you need to clear cache for your web browser, it has built-in features for that, too, often while giving you more control over what to delete and what to keep.

All these apps do is compile a lot of these options into the same place, and there's a benefit to that, sure, but it's not like running these built-in tools is particularly difficult or time-consuming, either. Is it worth having another program on your PC, especially if it could be collecting your data or trying to sell you on things you don't need?

Plus, the idea that clearing your cache and deleting temporary files is somehow going to make your computer significantly faster is something of a myth. Sure, it will save you some space, and that can help performance if you're extremely low on disk space, but in most situations, it won't make a difference. Plus, cache is usually kept in order to load things faster. Deleting cached files can actually result in some things taking a little longer to load next time because there are no cached copies of certain files.

You're better off trusting your computer's ability to manage cached files and only occasionally cleaning up files to free up space. Once every few months is more than enough to keep things running smoothly.

Registry "cleaners" are a scam

Just leave it alone

Another feature many of these apps tend to try and sell you on has to do with the Windows Registry. This is a major component of Windows, and it stores a lot of crucial information that keeps your computer running as expected. Apps can write and modify the registry to configure certain behaviors, and sometimes, if you remove an app, its registry keys may not be deleted, leaving some unused entries in there.

Some apps will claim to clean your registry by deleting a lot of these leftover registry keys, but in reality, there's rarely a benefit to this. Unused registry keys are just that: unused. And these are incredibly small pieces of information that take next to no storage on your PC, so the performance impact is essentially null.

There's a very unlikely chance that a leftover registry key could cause the computer to expect a certain behavior, and if the associated app isn't there, that behavior could break. But this is a very rare occurrence, and you're more likely to accidentally delete registry keys that are still useful than to actually benefit from running these tools.

Freeing up RAM isn't necessarily good

Just restart your computer

Another kind of tool you might find that claims to help improve performance is a "RAM cleaner", which tries to free up memory on your PC by forcing some background tasks to stop. That may seem like an easy win, but once again, you're better off if you trust your computer to manage your memory by itself.

Memory in Windows 11 (and other OSes) is never designed to be wasted, and things are only saved in memory to speed up processes. Your web browser will keep tabs in memory so you can more quickly switch between tabs without having to refresh the page, and the same can broadly be said for any app you have open. Things are kept in RAM so that they can load faster when you're juggling multiple tasks.

You can use a RAM cleaner to close things out and clear that space, but it's going to fill back up quickly, and that's a good thing. RAM exists to be used as much as possible. If you do run a task that requires more RAM for itself, then of course, that space will be freed up for the primary task at hand, but having higher memory utilization during normal use is not a bad thing.

What can you do?

Be more conscientious

If you want to improve the performance of your computer, it mostly comes down to being a more proactively responsible user. You can improve performance by avoiding installing too much software you don't need. When you install a program, make sure to disable any additional programs they may want to bundle in. That's a big step, especially because a lot of the time, this bundled software is probably not that trustworthy to begin with.

Then you may also want to monitor your startup apps. A lot of programs you install may try to start some tasks alongside your system, and some of them can be important, but others you probably don't need all the time. This is usually up to your own discretion, but you can use Task Manager to take a look at your startup apps and see what might be slowing your PC down unnecessarily, and try disabling some tasks to see how it improves things for you.

And of course, keeping your storage as free as possible can also be beneficial, but you can use the built-in Windows tools for that, and manage some of your files manually. Checking for duplicates or old downloads you don't need anymore can be a good idea, so it's a good idea to check out your downloads folder every now and then.

Naturally, you'll also want to avoid any shady websites or programs that may infect your computer with malware or spyware, as that can also impact your computer's performance. Windows has a built-in anti-malware suite, but you can also use a tool like MalwareBytes for a deeper scan every now and then.

Installing more software is rarely the solution

At the end of the day, installing more programs is rarely the solution to get better performance. Nothing will have a bigger impact than simply being more careful with how you use your computer to avoid loading it up with unnecessary junk — a term that can include many of the "performance optimization" programs out there.
