How can I speed up my Windows for free?

If your computer is running slow and you want to speed it up for free, then there are many ways of doing this within Windows 10 and Windows 11.

The first thing you want to do is ensure that there are no programs, software, or apps booting up with Windows in the background that use lots of resources.

If there are then disabling these will easily speed up your computer.

Another thing you will want to ensure is that the inside of your PC or Laptop is clean and has not collected lots of dust that could be slowing down your system. But just be careful when doing this!

And finally, remove the software from your computer that you no longer use. These are just three things that you can do to help speed up Windows for free, but I have listed many more ways of speeding up a computer below.

Does updating Windows make it faster?

When it comes to doing Windows updates, it is very important as it will offer security patches, and new features and fix known bug problems. But does updating Windows make it faster?

The answer to this is yes, it can help speed up Windows 10 and Windows 11. Especially if you are using a really old version.

But not all updates have always helped improve the speed and they have actually caused problems and slowed down the operating system, so it is basically down to trial and error.

I would recommend you update to the latest version of Windows so you get the latest improvements, which should make Windows faster. But if you do have any problems then you can always remove the Windows update or remove a feature update.
