I bought an SSD and installed Build 14267 on it.
I disabled fast startup and the computer now boots the first time. Still blazing fast on startup. Outlook now starts like it should instead of taking a whole minute to start.
However, if I walk away from the computer and let default sleep take over, when I come back, the blasted thing is completely frozen and I have to do a hard shutdown and reboot.
Anyone else having this problem?
