Windows 10 Fall Creators Update
This past Thursday I formatted and clean installed Windows 10 Fall Creators Update, which went very well. My system boots up faster than with the Creators Update, and I haven't experienced any bugs or issues yet.
The only odd thing is it created an EFI System Partition on my drive during the install; never seen that before. It's only 100MB though so no big deal.
Instead of formatting I did the update install for my father, and that was frustrating. It took the exact same amount of time as my clean install to just upgrade the OS! For me, I formatted and got the OS, then the MB drivers, then started re-installing software and such and it took me 3.5 hours. Just to upgrade my old man's system took the same amount of time. That's also because the download hung for about 45 minutes and I finally had to force the system to shut down and then resume the update.
My father's also experiencing a few bugs, mostly nuisance stuff, such as needing to sign in twice to get to his desktop (I've corrected with a workaround for now).
So while with the Creator's update upgrading was easier than formatting, it's been the opposite with the Fall Creators Update for me.
