Downloading.

All done. Very quick update.

Installed quickly. No problems noted.

Still has ESENT errors ??

Surface Pro 3 had already downloaded the update and was waiting for the manual restart. So far, so good. Will report back if things turn out otherwise. Surprised to see a Slow Ring update: maybe we will see 2004 in May, after all!

The update(KB4552455) went surprisingly fast for me as well.

Did anyone else experience a kinda staggered install?

I haven't monitored previous windows installs as closely, so what I describe could be the norm. On my end, ~15(?) minutes after the install>reboot completed, another update labelled KB4552455(identical KB) appeared. The updates secondary download was small, and no reboot was required post-install.

If it is the norm, then it looks like I learned something today.

I've not noticed that but you sometimes get two install phases before the reboot. That is caused by a servicing stack update. I didn't notice it with this one though.
