Then I figured perhaps it was some shell extensions that is causing the problem. I didn’t think it was virus because I could not find any suspicious autostart entries. I checked Windows Task Manager and there isn’t any process that shows any high CPU usage during that 10 seconds.
Weirdly after using the laptop for a few weeks, a problem started to appear that is the computer sort of hangs for a while about 10 seconds whenever I right click on a file or folder. This time I am very careful on what I install because I do not want to slow it down and then had to reinstall windows and set it up all over again. Well I normally install and test software on my desktop computer but sometimes I am too lazy to boot it up so I ended up installing it on my laptop.
I’ve recently reformatted my laptop’s hard drive and reinstalled Windows because it was getting a bit slow and also unstable.
