To be sure, Win10 Anniversary Upgrade crushed one big bug, me! After working for a year under Win 10 on my trusty HP Elite 8200 CMT with Quad i5-2500 and 16 Gb memory, and an ATI Radeon HD 5450 video card, the Anniversary Update brought the machine to its knees, and first, the video started giving trouble, then the webcam, then the printer, and finally someone on the AMD forum acknowledged that the drivers for Win10 were failing under the Anniversary Upgrade... For one brief moment, I thought of buying a new machine, but this machine has been a reliable workhorse and is plenty fast for day-to-day work. In short, after 25 years of saying that my next machine will run Linux, and periodically having at least dual-boot machines (though not this one), I finally decided that it was time to switch to Linux, specifically Linux Mint 18.1 Serena, and it's working like a charm. Since 2000 first Open Office and then LibreOffice had already become my main office suite, so the culture shock was not too great.
The only way windows is coming back for me may be as a VM, on my next killer Linux machine, which will have all the memory it needs to do that. But I don't like to have dual boot for an OS I need to use once or twice a year.
