Thank you bob3160 for this topic and your and others' help here.
Upgraded to Win 10 Home 64-bit from Win 7 Home Premium. Total time: 52 minutes. Checked for WU's and picked up two more:
as well as the original one installed with the upgrade: KB3081424. So there are three total so far, or am I missing something? Have the .NET Framework 4.5.2 updates (3), and Visual C++ 2010 KB's for both x64 and x32.
Must say upgrading went pretty much without a hitch, except where user accounts had significant data inside. These accounts, when updating, took a little longer than expected to complete. Win 10 said as much.
Only real operational issue(s) seen so far are with Windows Shell Experience Host (non-responsive or hang), explorer.exe (hang and crash), Cortana (stalls and terminated by Windows), and Edge (unfinished product).
With WSEHost, it was impossible to enter the settings window to change the default from Edge to FF until several restarts seemed to clear up non-responsiveness. Once this issue cleared up in each account I ran, I was able to enter settings and make the changes.
System indexing ongoing, maybe why this was an issue? And why explorer.exe seemed to crash and hang? Reliability Monitor shows 26 critical errors and counting in the above programs so far, not including Edge, which seems about right for an upgrade install. But improving over time.
Edge is fast, but needs much work from what little I've seen of it. Agree with schmidthouse here. It does not work with Belarc Advisor; it only presents a dark screen where the system information should be; total lack of any content. Interestingly, Belarc claims Win 10 is really Win 8.1 in FF.
-Noted that Edge comes with Adobe Flash installed.
Any way to remove this? (If this has been pointed out earlier, sorry, I've missed it somehow.)
Last time I upgraded was with Win 98SE, 17 years ago. Didn't work out that well back then.
