Stop PresentationFontCache.exe hogging CPU power

Recently, I’ve come across an annoying problem in Windows 7. There seems to be a service, named PresentationFontCache.exe, that hogs CPU power for an extended period of time – which can be extremely annoying when playing games or using CPU-intensive applications.

From research, the service seems to be part of the ‘Windows Presentation Foundation service’ and doesn’t appear to be anything harmful – just a nuisance. It would be a bad idea to kill the service permanently as it is quite important (although many have resorted to killing it without major issues), however there is a good fix which I’ve come across.

To fix the problem, we simply need to remove the cache that it creates.

Head to C:\Windows\ServiceProfiles\LocalService\AppData\Local (it won’t show up in Windows Explorer – you’ll need to manually navigate to it). Now in this directory you should see up to three files – named as follows:

  • FontCache3.0.0.0
  • FontCache-System
  • FontCache-S-xxxxxx….

If you delete the file FontCache3.0.0.0 whilst the PresentationFontCache.exe service is killed (kill it from Task Manager), it should resolve your problem. I actually removed all three files and it hasn’t done any damage, but I’m relatively sure you only need to remove FontCache3.0.0.0. Apparently, in some cases, the file may be called FontCache4.0.0.0 – in which case remove that file. 

Once that’s done, reboot your computer and all should be resolved!

Internet Explorer 9 not for Windows XP

Inevitably, Microsoft has drawn the line from Windows XP and clearly they are attempting to slowly pull people away from XP and onto more recent versions of Windows.

I don’t suppose it concerns many people anyway – who wants Internet Explorer? Firefox is several times better and Chrome is another story altogether.

Nevertheless, it could prompt Mozilla and Google to start deciding when the pull the plug on support for XP for their programs.

If you’re still one of the 65% of us using Windows XP, you really need to consider moving on. Windows 7 is much more practical (despite the pathetic TV commercials by Microsoft). XP has really past it a bit.

Microsoft Security Essentials – hands on…

It was in tech news today that Microsoft has let loose its new free security system to replace Windows Live OneCare. It’s been expected for release for quite a while but we didn’t know an exact date.

So, GEEK! decided to have a quick go with the new software and see whats up.

You can download it for free here, providing you have genuine Windows software. The download is under 5MB, so you don’t have to worry about a large download. Once it is downloaded and you run it, it will do a verification of genuine Windows software, and then it will install. Installation is remarkably quick, and before you know it the software will be downloading updates.

Surprisingly, this took a very long time. It took nearly 10 minutes for my mid-spec laptop (dual core, 2GB RAM) to download the relevant updates.

Once it had finished, I did a quick scan. This wasn’t too bad actually. I was quite pleased at how little resources this used. While it was scanning, my computer told me it was using about 7MB of RAM and very little CPU power so I was very impressed at how quietly it runs.

I also did a couple of hours of browsing around the software. I have to say it is extremely simple to use and navigate.

I’d like to see it become popular because I’ve always had my views that paid antivirus is a waste of time.

In my case, I won’t be keeping it because I like Comodo Personal Firewall a lot, but if you’re a novice computer user and you need a simple way to get protected, this might be for you. It will work on Windows XP, Vista and 7 and as long as you have genuine Windows software you can get it for free.

I have to say I like it, but I’m looking forward to seeing if it gains any form of popularity.
