Microsoft Windows 7 is among the one of the fantastic operating software and even though Microsoft has stopped releasing its updates, it is still used by the millions of users.

There are two versions of Windows 7 in use, one without any Service Pack and one is with Service Pack 1.

This is where the problem comes as the windows without the service pack sometimes does not support many new softwares like Adobe CC or Camatsia (these ones I have tested personally)… so to resolve this many of us installs a fresh Windows with Service Pack 1.

However here I have given step by step process, but for those looking for a video tutorial can go through this video (in Hindi)
