Your operating system may take more time at the time of start up because it has too much load of processes at the time of startup, at the time of copying a file your operating system may slow down because of unavailable buffer memory, when you are gaming you may suffer lag because of running of several unwanted application in the background. So, if you want to speed up your system’s performance you have to reduce the number of processes which get launched at the time of startup, clear your temporary memory files and close the unwanted applications running in the background.

Hi,was a great help.Thanks.Just on registry tweaks step 2 where you say to change Mouse Hover Time from 50 to 100,mine is set at 400,just like yours is in the illustration above before you double click it to change the value.Is it right for me to change it from 400 down to 100?Thanks again mate

Hi Dave, It is absolutely safe to change the value. It will speed up your Windows 8. If you want to know how? I can explain it..

I went through all your suggestions and I would swear that my computer is now slower. Have you had any similar feedback? Do you have any idea why it seems slower now? Should I just cut my losses and try to put things back as they were?

Hi Mark,
Sorry for that. I don’t know why it didn’t work for you. Many people have found this article useful, as you may see above comments. If you are trying to fix a slow Windows 8 PC you may want to check A guide to fix slow Windows 8 PC.


Really useful thank you

After following these instructions and then restarting my PC, I found that my touchpad no longer scrolls… Any suggestions?

I guess you have disabled scrolling. Is it only the scrolling or your touchpad is not working at all?
