Why Windows PC gets slow over time and how to speed up it

There are few things more frustrating than a PC that starts running slowly. You know how it goes — you buy a brand new Windows PC and it runs smoothly and speedily, doing everything you need it to without a hitch. Then, gradually, your PC runs slower and slower until you find yourself sitting waiting for applications to open, documents to save, or even just for Outlook to display email.

Why does Windows PC slow down?

There are a number of reasons your PC slows down over time. For example, as time passes and hardware improves, updates to Windows and to drivers and applications are designed to take advantage of the improvements. That can leave older hardware struggling to keep up. In addition, hard drives, with mechanical moving parts that are used hundreds of times a day, get slower as they get older. But ageing hardware is far from the only reason you have a slow Windows PC. 

One big factor is the software you run on it. As you download updates and install new applications, you fill up your hard drive with all sorts of files. The more space these files occupy on your hard drive, the less room there is for virtual RAM. This will slow down your computer.

In addition, the more software and other files you have on your computer, the more time Windows has to spend checking for updates, which slows things down even more. And the more apps and other software you have installed, the larger Windows’ registry becomes and the longer it takes your PC to sift through it and find the data it needs when you run an app that uses it.

Finally, browser extensions can be a cause of a PC slowing down. If you have lots of browser extensions installed, it can make your web browser sluggish. And as most of us spend a large chunk of our time on a computer working in a web browser, that can feel like the whole PC is running slowly.

How to speed up Windows and fix a slow PC

Now that we’ve established the main reasons you have a slow computer, it’s time to explain how to fix a slow PC. There are a number of drastic steps you could take, such as:

1. Install more RAM
2. Fit a larger hard drive
3. Re-install Windows as a clean installation

These will all speed up your PC, but it’s likely that none of them are really necessary. There are lots of other things you can do that will speed up your computer without taking a huge amount of time or costing a lot of money.

Check that you’re running the latest version of Windows and latest drivers.

1. Press the Start button and search for Settings app
2. Click on Update & Security then Windows Update
3. Choose Check for Updates
4. If the status says “Updates are available”, click Install Now
5. Select the updates you want to install and select Install
6. Restart your PC

If you are running the latest version of Windows and all your drivers are up to date, or if your PC is still running slowly after you update, there are a number of other steps you can take. These include: optimizing Windows registry, uninstalling applications, and disabling autorun items.
