LOL, in that time period, I have installed and deleted at least 50 Windows 10 installs. I wonder if they have made correction to encompass this way of working*
Then the next question, as coolcolors correctly points out, how many stayed with the OS?
In my experience, current Windows 8.1 users get along well in Windows 10 whereas Windows 7 users go dang, shit and can't really see what is to be gained.
*Earlier I used sandboxed environments, but once some advanced malwares was able to jump out, I changed the routine and use disposable isolated VMs instead whenever doing work on 'dubious' files and distributions.
