This update must be done manually. I checked.
As you can see I'm not running the latest version even though I have kept my machine updated.
And you just have to let it do it's thing since it's going to download whatever huge file this is. This is the part that sucks since you don't know how big the file is. For whatever reason Microsoft decided not to let you know. The installer is 5.5MB but the rest is just a large file. The good thing is that this is all you probably need right now other than maybe a restart when it's done.
The icons have been moved to the left on the start menu. I prefer the minimalist view so I don't have those large app icons taking all that space.
Warning: Make sure you do the upgrade and not the refresh. They both update to the latest version as I just checked, but the refresh basically wipes out all your apps and data if you want. So all my programs are now gone on my laptop which I have to re-install. The process is very similar so you can actually wipe everything on your computer if you're not careful. I only had the option to keep the data and take out the apps, which I thought was just referring to installed apps and not actual programs I had installed manually and not through the windows app store. So the good thing is that I still have my data, but none of the programs I had installed and the OS is just like when you first installed windows. Which is fine if something funky was going on with windows but I was just trying to upgrade the laptop as well. I hadn't done it so its nice to know.
