Original title: Windows 10 upgrade.
Hi,
I recently upgraded my pc to windows 10 from Windows 8.1. During installation, in the step where we are provided option to choose partition where we want to install windows 10, I chose my current windows 8.1 installation partition (ie. C partition) . After
installation I saw a folder in c partition which was named as windows.old. I surfed about it online and found that it could be deleted via disk cleanup. My question is that is it safe to do this ?
