My daughter changed to windows 10(she has a laptop) and it did not load properly, she finally gave up and took it to a computer specialist,it cost her a little over a hundred dollars. but she said its the best money spent in a long time .I have Windows 7 on all 3 of my computer devices(desktop, tablet and cell phone ), and am going to take my desktop to a specialist (Computer Doctors) to upgrade it, as I'm starting to have some problems they say windows 10 will fix.My desktop is 5 years old and can be a great pain at times.I'll have to buy a new Kindle fire to get Windows 10 on a tablet(no upgrades on it or my cell phone.)
