What is sqmdata and .sqm file in windows 7 and how to delete them


If you’ve ever turn on show hidden files in the folder options, you will likely observe sqmdata and sqmnoopt all .sqm files on your root partition usually under the C drive. Although, the file are relatively small but annoying to have a huge list of them on your root directory. So I did a quick Google search, found out that the .sqm files are for Microsoft Live products, so software like Windows Live Messenger (MSN) and other Live packages will create those file. “.sqm” file is stand for Service Quality Monitoring. Its a list of files that collects information and used by Microsoft to help to improve their products, by monitoring the usage of the software. You can stop those files being created.

  1. Go to Help > Help Improve Windows Live (Hold Alt if you don’t see the tool bar option)MSN help improve windows live
  2. Click and Choose do not participatedo not participate

You are done 🙂 This will disable the .sqm file being created, and hopefully you will have a clean root directory.



    • 1: Then you need to go to a different Windows Live Program and find the “Help improve Windows Live button”

      2. Execute “C:\Program Files (x86)\Windows Live\Installer\wlsettings.exe” if you use an x64 computer or “C:\Program Files\Windows Live\Installer\wlsettings.exe” if you use an x86 computer, and disable the second option.
