I have been testing Win10 from the very beginning. Nice to see 9926 fixed the many reported keyboard issues!! I have not had the start menu problem that others have posted but each time I shutdown or restart my Toshiba laptop, it takes 2 hours to boot up. There is no error message, no updating %, it just says Please Wait for almost 2 hours and then I get the sign on screen and it loads the desktop normally. There are no pending Windows Update items and no error messages at all. Anyone else having this issue?
