Error: We couldn’t complete the updates, Undoing changes. Don’t turn off your computer.

Robert, although I appreciate the frustration that has been expressed, I find your posts quite useful.  I have tried many of the suggestions proposed by you and others.  Unfortunately, I am one of those where there is no 'smoking gun' - no error code and no obvious errors reported in the logs.  I am also getting error 0x800f0922 trying to install KB2961908 which may or may not be related - I have a ProcMon trace that I need to analyse.

I am trying to become proficient in using ProcMon.  It has a way to trace events early in the boot process which may help identify why the changes are being rolled back, although I wonder if the number of reboots will result in lost trace information.  I have contacted the folks at Defrag Tools (they ran a number of tutorials on ProcMon) about using Update 1 as a real-life problem determination case study but have not heard back.  

I have a clone of the failing system and plan to try a repair install using a recimg created from a laptop where Update 1 successfully installed.  I can also revert the system partition back to April 9th before the trouble happened to see if KB2919355 will install.  I suspect the recovery partition on the failing laptop has been corrupted - when I try to create a recovery backup, I do not get the option of including the fully recovery image in the backup.  Unfortunately I simply do not have the block of time required to do this testing - I keep hoping Microsoft will pull the rabbit out of the hat.

Now that the cut-off for fixes is once again looming, I am composing a strongly worded email to the Director of Public Relations at Microsoft about the poor communications and support .  Microsoft needs to get ahead of this issue before it spirals out of control.

BTW how's that  ISO idea  working for you?

Unfortunately due to the policies of the company you seek badges from I don't have a disk yet. But I eventually will.

Thanks for the link to that old thread. I got a laugh about the irony when I remembered the original poster, after jumping through hoops for two weeks, finally gave up and did a reinstall. But as you said, maybe he learned some new things in the meantime.

Since I 'only' have the OEM key which came with my Surface Pro (from Microsoft!!) I cannot access the retail ISO

Do you know exactly what you want from it?  Perhaps it is content which is already available to you in here:

Whatever that is, it is certainly an impressive collection of stuff.   <eg>

Or is that what some people are finding has been "wiped out"?

Are you so mired in the weeds yourself that you cannot see that your posts are of little assistance to the average user/customer?

I was trying to rebut your "no resolution" comment politely.  In fact, I think you're wrong and that there are all kinds of people who frequent these forums, who get ideas from them and are willing to try learning new things by solving their problems themselves.

Amen!!!!
