Windows is a fantastic operating system, but it still carries the same flaws and problems that users have often complained about in the past, with some important improvements when it comes to Windows 11.

This OS, no matter the exact version, can become quite bloated if you don’t take good care of it – and this can cause serious performance issues, while also occupying the hard drive of your device with clutter.

Even though things have improved since Windows 7, even the latest releases of the OS have some clutter here and there, even though the OS is considerably more optimized for performance.

Usually, the best solution to this is to format Windows and reinstall it, but there are things you can try before doing that, as formatting your hard drive takes a long time, and the moving of data is quite cumbersome for most users.

Optimizing your PC’s performance can be done with specialized software that allows you not only to remove and replace any files with issues but also to refresh any registry files that have been left behind from previous installations of software.

To dive even deeper into this subject, you can also choose a RAM cleaner and optimizer for Windows 10 or Windows 11.

This type of software is called a PC optimizer, tune-up utility, or PC optimization software, but they all do the same thing, which is making your PC run better.

Does Windows 10 have an optimizer?

A PC optimizer is a software with a good-looking and encompassing user interface that allows you to streamline the process of tweaking your PC and making it run smoother and better.

The market is saturated with a wide range of PC optimizer software, in all shapes and sizes, and with a variety of features.

As we all know, not all software is created the same, and this type of software is no different, with some having a plethora of useful features, while others have a more limited number. Beyond this, the overall efficiency of software will vary considerably, in strict relationship with the cost of the app.

No matter if you’re interested specifically in a Windows 10 optimizer for gaming or simple day-to-day usage, the list provided in this guide will cover your needs.

Tune-up utility/ PC optimizer pricing

Even though prices on the market fluctuate considerably, and offers are updated by the owners constantly, the pricing of a good PC optimizer tool will be starting around 20$ and depending on the version of the software, can also reach 45$.

There is of course a large spectrum range in the prices, both between the software options themselves and also because of the variety of licenses for each of them.

Added to that, there are plenty of options that also offer free trials or even a Windows 10 optimizer that is completely free.

It is worth knowing that while the software options with free trials could be useful, their capabilities are restricted, while in the case of free software, the level of optimization might not be up to par with your PC’s needs.

How do you find out what is slowing down my PC?

One of the best freeways to find out the source of a problem is to make changes to your PC sequentially.

This means installing new software, adding new hardware, and more, since you can then tell which new addition to your system is causing the performance lag.

The usual culprits are antivirus tools running in the background, which is why many of them come with built-in optimization tools to compensate.

Another way of finding out what is slowing down your PC is to look into the Task Manager and see what is using up most of your RAM, CPU and how many items you have configured for automatic startup.

Why is my PC so slow and unresponsive?

Before all else, ensure that your PC isn’t too dated for the programs you are trying to use or that not too many programs are running unnecessarily or in the background.

Additionally, ensure that your PC’s registries and DLLs are running accordingly. If you notice these are the problem, then a good registry cleaner will do you good.
