Suffering with slowPCitis? – Help is here!

(Last Updated On: March 27, 2019)

Why is my office computer so slow?

For those of us that work in offices there is one constant companion, the office computer. The work PC. It’s part of your landscape, shares your desk with you, greets you every day and waves goodbye at night.

But it can grow to hate you! You might scream – why is my office computer so slow? But inside it’s secretly crying!

(Sad Panda is mad, mad at his office PC!)

It turns out that as well as having feelings our computers need to be cared for. There are many different schools of thought on how best to keep a computer running well. Ours is no secret and is here for you to use!


Cleaning a computer is easy. But you might not have the ability to do it if your computer network has been secured. If it has then you’ll have to ask your IT Department or IT support provider to assist.

Here at Technology Simplified we recommend a good PC clean at least quarterly. We will provide it as part of our managed service.

But for now you just want to clean it don’t you?

We use the following software;


These three will actually do a little more than clean the PC, they’ll also help you with spyware.

You can go ahead and install and run all three. With CCleaner run it until it’s not able to find any more junk, same with it’s registry cleaner. Once you’ve run them you can remove them!

There are different opinions on cleaning software. This article from How-To-Geek suggests that they’re a scam. But over time the software mentioned above seems to provide an actual improvement so we keep using them.

Disk Clean-up

Another powerful tool is included within Windows. The disk Clean-up wizard. Hold your Windows key and tap the R key. Type in the following “cleanmgr” (no quotes) and hit enter.

You should get a window pop up called “Disk Clean-up : Drive Selection” and you can click on OK assuming it’s showing your C: drive – most PC’s main hard disk is “C”.

Once it’s done it’s scan you will see a list of things that can be cleaned. Tick them if you want them gone. (Authors Note: Avoid Compressing your OS drive – it can hurt not help speed!) For extra clean click the “Clean up system files” button and repeat

It’s worth mentioning at this point that if your hard drive is full – the PC will be REALLY slow. Chances are if that’s the case you might need to invest in a larger drive, or you seriously need to have a spring clean!

Your temporary files folder could be full of junk. If you hold the Windows key and tap R, type in “%temp%” (no quotes) and hitting enter, then deleting all you can from that folder that may give you some space back.


This might sound like an industrial mining technique but it’s actually another great way to speed up a slow PC. Windows has software built in to do this but we like to replace it with Defraggler.

Not just because the name is cool, but Defraggler actually gives us some additional features that make it just a bit better!

Best advice we can give for this job is to download, install and let it run overnight. If you’ve not defragmented your PC before then the first time will take a while.

If you must know, defragmentation is a process of reorganising the files on your disk into a much cleaner and faster layout. ALL PCs files will become fragmented over time.

IMPORTANT : If you have an SSD hard drive you SHOULD NOT defragment it. The technology is different so defragmentation isn’t needed. If you do it could reduce the lifespan of the drive. Defragger offers SSD owners an option to optimise their drive instead, so use that.


Get rid of anything you don’t need. Many programs are installed that are hardly ever used it’s possible you could just have a few unwanted items lurking on your PC. Unfortunately many programs that now “offer” extra stuff, our cleaners up there? Even those try to force you to have a copy of Google Chrome if you don’t have it.

(Authors note: I do not have a copy of Google Chrome on my computers – but that is a whole other blog post for another time!)

You can also reduce the number of programs that automatically start with Windows. But that’s not quite as potent as just removing the junk in the first place!

If you want to disable programs from starting with Windows right-click the taskbar and click Task Manager. Then click on the Start-up tab. Anything you see in that list you want to stop starting just right-click and disable.


I recently worked on a PC that had 30GB of data on it’s desktop! The owner complained that it was a “bit slow” loading. Your desktop is not your documents! If you can, really try not to stash too much on the desktop. Create folders elsewhere and use shortcuts.

The Nuclear Option

If you have tried all of the above and STILL your PC is slow then you might have to consider upgrading.

If you have an older style hard drive a quick win for increasing speed could be to upgrade your hard drive to an SSD drive. These can give slow PCs a massive boost.

But we’re not talking about that today. I’ll post on how to do that later!
