I have a question for the hivemind - If I completely REMOVE (not just hide...) the Windows 10 tray icon / program, can I still upgrade to Windows 10 later when they are on...ohhhh...about update 8 or 9 for it? I WILL want to go to W10 someday, just not right now, or probably in the next month or so.... I used W10 for 5 days but I had SOOO many issues I went back to 8.1 - battery substantially less, Fan on all the time / hot with 1 browser tab open and nothing else going on / Cortana running in BG but only actually working 1/4 times... So, yeah. Definitely shows promise, but not for a while... If anyone has an good answer I'd love to hear it. The program seems to be occasionally sucking down a bunch of bandwidth and CPU occasionally. I'd love to get rid of it... Temporarily.
