I am running an upgrade right now have not done a fresh install.
requires time as it may be a personal laptop but i use it for work out in the field they expected me to use a window 8 7inch toshiba tablet like a laptop still sitting in my closet a year later.
But yeah maybe that would work it boots fast but then to a black screen for a few minutes then afterwards it loads the login then once i login even that takes awhile. My Dell desktop take 31 second to load to flash screen. Programs, internet pages, all seem to load faster than my computer did with Windows 8.1.
Getting a black screen for a few minutes at boot is not normal. Yeah So i ended up backing up my important data and doing a clean install much much better it runs a lot better, I'm actually now considering next weekend doing my desktop so far i'm actually liking windows 10 there are somethings i don't like.
In the case of our PCs, however, it’s not the hardware components but the operating system and software that degrade over time due to regular computer use.
