I only have the Win 10 update ready for install. But I got a forced update this afternoon. My laptop was in sleep mode and came alive. Took sometime. Much longer than an 8.1 update.  Wondering if that is the update for installed Win 10.

I've upgraded two computers now and am very happy with Win 10 thus far, particularly now that the new Yggy driver has dropped.  Favorite feature so far: right clicking the start button gives you access to just about everything important in a single consolidated pop up menu.  Where have you been all my life!?!

I went the media creation tool route and just ran the upgrade.  Only minor issue was that Win10 did not have native support for the touchpad on my N56VZ.  Should have thought to find that in advance so I wouldn't have had to pull out a spare mouse.

Upgraded two PC's, one hi-end (5 year old, at the time absolute top) i7 full tower, and one small Lenovo i3 laptop, first PC got upgraded in approximately one hour only, and the laptop in about two hours.

Both work perfectly fine and are noticeably faster.

No problem with drivers, software or anything else.

I am very happy and i think Microsoft has nailed it this time...

PS. The i7 tower had severe problems when i installed win8, when they first came out... and about two weeks after installation i reverted back to win7... from my impressions so far win10 is here to stay!

I hope I do not have to reinstall Office.

I didn't have to reinstall.  Plus, the integration in 10 and Office is much better now.  The "Action Center" notifications, recent files and OneDrive all work well together.  I'd had issues in 8.1 because I encrypt everything before it goes to the cloud so it continuously screwed things up.  Windows 10 is working perfectly for me, which is really nice since I didn't have to eliminate or downgrade my security to do so.  I did go through and check/uncheck as necessary to not share anything with Microsoft etc. so I feel in a pretty good place re privacy, sharing just enough to make the integration useful to me without giving anyone access to more than they should have.  I definitely got rid of the Bing search in the bottom left so it just searches my computer.  Also turned off Cortana, although I might revisit that in a year if it turns out to be useful.  The future will definitely be voice (or mind) controlled so I'm just being an old curmudgeon by not adapting yet....

Easiest Windows install by far, i mean the upgrade.
Click 'Ok' and 'Agreed' few times and done. My grandma could do this.
First look: As W7 should have been in Vista's place, W10 should have been in W8's place. I like it.
