Build 25267.1000 is live in Dev, ISO out

I had same kind of issue with second hand device I'm about to buy and that issue worried a lot when I start testing this device. (W.U. work fine on my other 3 Dev channel devices.)

On first few attempts with W.U. or ISO I force shutdown too early when display goes off in 48%.

Then I download ISO's for some older builds and in-place update completed without issues.

When reading your experience I decided to give that device another change.

Working on updates goes up to 30%, restart, then long time in 48% and after 15-20 min waiting in 48% display goes dark for about 15-20 min. Then display wakeup again in 48% and then it start very slowly goes to 60%, 63%, 68% and restart at 75%. Then update completed without issues.

I think this could be a CPU problem. My main dev PC has a similar CPU, with the exception of missing graphics. No problem with the update. All other hardware is identical

Tried again and succeeded! Left it alone for a few hours.........

You're welcome, good luck!

Tried to delete the driver, but the system wouldn't let me

So decided to try again and finally succeeded with the install. Just left it for a few hours. Hope the next build gives a better result

You need to uninstall the printer software or disable the running printing services first.

Good to hear that. For some reason update process was radically slower compared to normal update.

It's not necessarily printer driver which caused that issue. When I did forced shutdowns Setupdiag give various results so it may depend on what phase that shutdown was done.
