Windows 10 the worst yet
I can outtype notepad
I keep getting screens overlayed on my machine whinging about security updates it claims it ant do as it needs gigs of hard drive (which it actually has)
It consumes tons of memory even before it functions and this increase over time
It updated itself 3 times last week moaning all the time it needed to again / taking 45 minutes a time during boot when I wanted to use the damned machine
Frankly I think Microsoft should offer all those who have had this monstrosity inflicted on them a free upgrade to windows nt or better still linux
