I've been using Windows 10 since it was made available...and I have to say...I'm impressed.
Some main features really caught my attention:
- Boot Manager: Because I have a PC with multiple drives (one with Win 7, the other with Win 10), it asks me which to boot up, and I can set it up to time out in 5 seconds to a default option...very convenient when having to switch.
- Multiple Desktops: this is really handy, specially when on multiple streams of work, it has allowed me to be able to focus on a task, and then be able to switch very easilly.
- Running Windows Apps on Desktop: this is actually one of my favorites. My kids really like the new Paint app, but because it only ran on a windows 8 tablet, I really didn't wanted to get one just for them to be able to play with it. Now they can play any time they want
I haven't really notices and specific crashing issues... only Itunes has been the one to act up almost any time I try to sync and have other stuff running in the background.
Hope this helps
