While the upgrade from Windows 7 to the Windows 10 Preview, in the background all was not well at all. Task Manager showed between 96 and 100% usage which would not go away. I left it over night and tackled the problem this morning but nothing I did worked.

Placing the original clean install drive back into the machine saw CPU usage drop over 90%, so there was obviously something very wrong with the upgrade. Time to bite the bullet and scrap the Windows 7 installation completely.

The clean install was fast and, at the end of it, there was some thrashing but it all settled down to 3 to 4% CPU at idle. At least, the poor little Toshiba isn’t going to wear itself out overnight.

In use, it is slow, using 54% of the 2gb RAM installed, but I don’t care. I have a Windows 10 test bed which is what all of this saga has been about.

Would I run an upgrade again? No, never…

Before I sign off on this, I did try out the Preview’s Roll Back feature, and I can tell you that it worked perfectly and was a lot quicker than I thought it would be.

Now, it is time to try out the other features of Windows 10..
