tried it didn't like it.
all the wonderful little tweeks you can do to your security/firewall etc, your scheduling of updates, backups (all that Control Panel stuff, essentially), gone. it's on or off, and even some of that is not selectable.
intrusive and downright brazen "snoopware" on the default install. ffs.
a 10 "App" limit on Windows software that can be installed on one machine. this repeatedly popped up on me. (don't ask--i have no idea)
absolutely no desktop gadgets of any kind M$ or 3rd party. not even the old clock.
some random 3rd party software incompatabilities that drove me to not even lasting 24hrs with this astonishingly wretched wad of stench.
just be careful: if your W7 is a gift from ThePirateBay, Taiwan, or elsewhere, and you choose to revert back from W10, you'll have to reinstall the M$N Key that you used, as Defender pops that little not genuine Woze nag tag and blanks your desktop background. just sayin. 
edit: btw if you are pestered by that annoying little white flag thing in the tray, see this: http://www.cnet.com/...stem-tray-icon/
