It went without a hitch. The update program works exactly as advertised. It went as smoothly as (dare I write this?) the OSX 10.4.5 update! The program downloaded the update, then it let me decide when to kick it off. I have been making triple backups, so I was not worried about losing anything. A piece of advice, the only reason YOU should not worry about the update is if you also have a backup. I backup my files to a USB drive. I also have a WD Cloud drive to which I copy my files, and which also serves as the drive for the nightly Windows backup.
I have been a member of the Windows 10 Preview since the Microsoft Build Conference in 2015. I am not sure how revolutionary it feels. The most obvious change is the start menu.
I was at the release of Windows 8 at Build 2011, and I thought it was revolutionary. Microsoft was going for the tablet platform in a big way, and we were all given prototype Samsung tablets to develop our first touch apps. Since then, the PC producers and consumers have played a cat and mouse game to determine what the best PC platform would be, and whether the tablet is really viable as a PC platform.
There are a lot of PCs out there with touch screens, but touch screen is not terribly convenient on a PC. The iPad and Kindle users believe laptop touch screens cause a malady called “gorilla arm”, as users reach up to touch their screens.
In practice, I have owned PCs with touch screens for many years, and the only screen touching that goes on is when other people point to things on my screen.
I have heard a lot of younger IT people gripe about how Windows 8 took away the beloved Start menu that Mick Jagger sang about in 1995. Having been present at the rollout of Windows 95/98 in many companies, I can tell you it was not a straightforward adoption. A lot of people really liked their old Windows 3 program manager groupings, and were righteously indignant about the Windows 95 treatment of them. The transition to Windows 2000 and Windows XP was not smooth either.
When Windows Vista came out with Aero, people rushed to upgrade and became dismayed because of User Account Control, and pronounced it worthless. Windows 7 was basically Vista with service packs rebranded, and now it is seen as a rousing success. In fact, it has been a hard act to follow. Windows 8 was booed off the stage. Now, as we are 4 years into Windows 8, and Windows 8.1, the PC population has become accustomed to it.
But here comes Windows 10, with a revamped start menu.
I actually liked the Windows button jump to my favorites. Now I have to transition them. I have been a big user of the Quick launch / taskbar pinning on the bottom since that functionality was introduced in the Internet Explorer 4 update for Windows 95. Most of my app launches occur from there.
Many corporate IT organizations finished their Windows 7 migrations by 2010-2012. I have been on a corporate build since 2011. At my company, I have been in the Windows 8 pilot for a year and a half. I only had two specific problems, and neither of them had to do with the operating system itself, more to support for corporate apps that ran on old versions of Internet Explorer.
I would expect large corporations to develop a transition plan for company PCs to Windows 10. Most new ones would be shipped with Windows 10, but downgraded to match a company image. At some point the home user population is going to demand the update.
