Just a quick update..besides taking a VERY long time to 'upgrade' my Acer Aspire 5100-3357 to Windows 10, I have discovered the upgrade from Windows 7 SP1 Home Premium Edition 32 bit didn't go as expected. Upon first bootup I found my system to be as SLOW as molasses, so this morning I'm doing a 'reset this pc' procedure. If all else fails, I can always just go back to windows 7 sp1 and then do a 'clean' install. Have a GREAT day !!
