Yeah, I had a failure to install message for the Nvidia driver while the new build was waiting for restart. Once I restarted and the new build installed, though, the new driver was there as well. No big deal, as I just ran DDU and returned to the older driver, but still a bit annoying.

Happy birthday!



Awesome. Thanks for the heads up!

Thanks for birthday wishes @blackroseMD1

Interesting!

How do you explain that I could successfully upgrade Windows x64 Pro EN-US Build 15063.0 on a 20GB drive (Windows minimum requirement for a 64-bit installation) to Build 16294.1?

My Windows.old ended up on the additional 16GB drive, I plugged in, as a WIM-file.

Never happened on my 32bit tablet - just gives up saying not enough memory and that is with 32GB usb stick fully empty plugged in.

What use is windows.old on another drive anyway unless system is designed to rollback from that?

Have you actually tried rolling back to see if that works?

I have actually upgraded a 64 bit tablet by making macrium image, using viboot vm on pc to upgrade, use disk cleanup, create new image backup, and restoring.

I could never get that to work with 32bit as Hyper-v does not seem to be able to handle 32bit UEFI.

Are you sure it's referring to disk space? Was the 32GB stick formatted as NTFS? Sounds to me that the OS ran out of RAM if the error message used the word Memory​.

Nope, but I will try that tomorrow, as it's late here. I doubt there will be any issues though.

What the heck, rolling back was just a few clicks away so tried it too.

Worked like a charm, except I am on 15063.608 now :)

Bad words - I meant disk space.

OK, was just checking.

Did you know that there is a minimum free disk space requirement for running Windows reliably? Also Windows supports upgrading when there is at least 8-9 GB free space (I don't remember the exact bytes).

I guess I have to try 32-bit Windows next on an even smaller drive to see if it eats my carrot too. :)

Interesting. Now that is what I like - "proof of the pudding ".

I suppose for this to work, usb drive would need same drive letter associated?

I wonder if MS have updated rollback mechanism with CU. It certainly never worked on earlier versions but they did add ability to use usb for temporary storage back at 1511. I will try again when I get a spare moment and report back.

I cannot imagine this would not work on 32bit.


As a separate aside, my favourite tablet app, touchmousepointer fails on Insider versions which rather puts me off upgrading even though I want 'Onedrive Files on Demand'. I use junction links so my onedrive subfolders point to data folders on my sd card instead.
