Well, I've just finished upgrading from Windows 8.1 to Windows 10 on one of my laptops. So far, everything seems to be running fine. Lenovo's System Update found no software or driver updates. Also, the version Lenovo Drivers Management found no driver updates. The upgrade caused StartIsBack+ to get replaced with the Windows 10 start menu. I don't mind the new start menu aprart from the fact that Modern (Metro) Apps are listed amongst desktop apps. I probably will never use these apps so it would be nice to have them kept seperate. I've got no audio latency issues - something I have exerienced on other laptops running the preview of Windows 10. Essential Update manager found and installed three Windows Updates. It's a good alternative to running the new metro style Windows update, since the desktop Windows Update wuapp.exe is no longer part of Windows, and it lets you select what updates you want to install rather than having Windows download every signe update. I may try disabling the Windows Update service, and see if I can still use EUM.
