I've used all the newer releases including XP Vista 7 8 8.1 and 10 which are all the same apart from features, We dont need newer because we're told that higher numbers are better than lower numbers , i don't know how much Microsoft have been in touch with Avast, but their tactics to get people to upgrade for security reasons! i'm not a fan now with their auto upgrades, they have full control over what comes in and goes even with what they "fixed" around that, and its accross the rest of their stuff, its bad enough with the internet that can be more and more invasive and forceful but nobody expects that from within their own desktop operating system.
I"m having to sort out a family members netbook that runs windows 10 home edition, but its only got 32 gb storage for the ssd, so i formatted it did a reinstall and ever since thats happened upon the first boot after restarting , it gets stuck on the windows logo. Now one would think switch to something else, but you can't do that anymore, not by CHOICE.
I did manage to install windows 8.1, i may even try attempting to install 7 as that is less bloated again, drivers provided by third parties, if hardware manufacturers are going to sleep with Microsoft then they must understand there's a cost, and Avast must understand that they are not the only ones along with AVG etc, people are not aware of open source, and if that becomes a bigger thing thats going to become a problem.
voluntary will always be better than business, they treat people as people. i've been turned down by local colleges because i dont have something in particular that looks good on their statistics or its because THEY don't think it would be best,yet the voluntary places i've worked for are very nice, more relaxed.
