I suggested that HG lengthen the time notifications are displayed. Either I was wrong about the setting being in Notifications or they moved it.
I finished installing no too long ago and went hunting. Nope the time to display notifications is not in Notifications settings.
But Search notifications (wow search is fast and good) found it in
Settings- >Ease of Access -> Other Options (Show notifications for [5 seconds ]
I wrote a post about installing Win10 on another thread. In my install notes, I mentioned that search from the taskbar did nothing (might be because I wasn't connected to the Internet). Then I wrote this post and said Wow - search is fast..... thought I'd note here that the search was initiated from different locations (Settings - good, taskbar - bad)-edit
