(If this has already been made, feel free to merge) Windows 10 launched today, and I've got my free upgrade from Windows 8. While it took 3 hours overall (had to go through all of my programs to prepare) the installation was otherwise smooth. As for the OS itself, it has fixed almost all of the problems Windows 8 had, although it has a few little niggles. The only technical problem I've had was when the Start menu wouldn't open, so I had to run a command in PowerShell to fix (for more info on this, click here), which seems to be a lingering issue from previews. Anyone else got their copy/upgrade yet?
