This is not good . Had an unused SSD laying on my desk so decided to put Windows 10 on my primary computer. Had a few problems getting it installed from my Build 10041 iso but finally got it updated to build 10061. Was having problems booting up and kept getting an initialization failed error. On a whim tried a restore point and low and behold it booted into Windows 10. Problem now is I can't open the start menu. Clicking on the taskbar icon does nothing and the ctrl/esc keyboard combo doesn't work either. It will be a bit of a pita but if all else fails I can plug my Windows 8 drive back in and format the Windows 10 drive for a reinstall. Wish Microsoft would hurry and post up a build 10061 iso download.
