Sorry. I somehow missed your last post. Just tried it and it didn't work either. I finally received a reply from Asus. She sugested hold down the Windows key and L simutaneously, but this had no effect. Anyway, I can now give a final (I think) report. Just for the laughs I thought I would have a go with the originl Asus T101 that refused to update from Windos 8.1 to Windows 10 bcause of insuficient storage (32GB). It remained stuck with Win 8.1 and I bought the second Asus (I think it's a T102) but still with 32GB. This was the max at that time, but it came with Win 10. You know where it stands now. But back to the original T101, I tried upgrading it to the latest Win 10, but using a USB memory stick to give it more capacity. You have probably guessed, it worked without problem and is now working with Win 10. Meawile, to complete the saga, I had bought another Asus T102 with 64GB of storage and that updated to the latest Win 10 without problem. I suppose the benefit is that I can now sell the origial, now working computer, and get some of my money back. That's the end of the saga. I still don't know what's wrong with number two, but I want to to thank everyone for their attempts to sort me out. It's been an enlightening exercise.
