I have Windows 8 x64 on my laptop. It is a while since its /windows/installer folder are growing! Right now it reaches to 160GB! I checked its content and it filled with .msp files with same size and same description but with different name! Would you please guide me through this problem?

Best regards.

  • This looks like files from Microsoft Office. Remove office completely. Are the files gone? – magicandre1981 May 5 '14 at 15:45

I use a tool from some Chinese website to delete unused files. It seems that most of those files were unused! Here is the tool that I used: http://appnee.com/wicleanup/
