No big surprises that I remember. It took me a couple of re-installs to figure out how I wanted to install Windows 10 as I was moving from Windows 7 and didn't know Windows 10 at all. But, once I got that figured out It's been pretty smooth. The operating system itelf has it's quirks, some of which I just don't understand how/why they exist, but they've proved easy enough to get used to for the most part and I'd see them in any version.
As to what I hoped for, I wanted this version as it gives me the most control over my system than any other version. No new and buggy feature installs to worry about, no silly windows apps preinstalled or continually reinstalling, fewer privacy issues and just generally a smooth experience.
As far as I can tell any issues I've had were Win 10 issues and not version specific.
I was looking to build a stable machine that would do everything from my gaming to my more serious stuff and I wanted as close to the same control of my system as I had with previous versions of Windows. None of this 'windows as a service' silliness with major updates multiple times a year. The LTSC version meets my requirements so I'm happy.
