Hi Dominic,
I tried restore (from safe mode) first without success. It rolled
back what appeared to be a partial update, but when I rebooted
normally the system immediately began to try to install the updates
again ... a vicious cycle that I couldn't get out of.
So I deleted the "boot.xml" and "pending.xml" files in WinSxS and
tried a restore again. This stopped the update attempt but left me
unable to log in on a normal boot ... I could log in only from safe
mode.
After trying everything I could think of, I ended up calling M$ tech
support. It took almost 3 hours to fix the problem. First challenge
was to get safe mode with network operating ... that took a couple of
registry edits on my part ... then the tech took over remotely. He
uploaded the logs of the update attempt and agreed that it had fouled
up royally. I tried to press him but he was noncommittal about which
of the 6 updates was responsible. He did say that I was correct to
delete the files from WinSxS, but he didn't understand why that plus
the restore had not solved the problem.
Anyway, he deleted a bunch of files and performed several registry
edits and about 50 key deletes (way too fast for me to follow it).
That restored normal login, after which he installed the 6 critical
updates one at a time. And finally he charged me US$99+tax for fixing
something that it appears was Microsoft's fault in the first place.
His sage advice was "best practice is to clean boot before each update
and install multiple updates one at a time with no other programs
running". Now I don't normally run anything while installing updates,
but the advice about "clean boot" certainly isn't practical for
non-technical users. And who has hours to waste installing updates
one at a time on multiple machines? I've seen up to 20 critical
updates delivered in a single batch.
I've been a professional software developer for Windows since 3.1 ...
I've never had problems installing official service packs, but over
the years there have been occasional issues with online updates.
However, system restore always has worked for me in the past - this is
my first experience of not being able to successfully roll back an
update and have a working system afterward.
I've educated my family about system restore and told them that it is
ok to install critical updates ... now I am seriously rethinking that.
I certainly don't have time to vet every potential update for the
dozen machines running 4 different versions of Windows (2K, XP, Vista
and 7) that various members of my family happen to be using ... and
none of them are qualified to do it themselves. In my case, I also
have multiple virtual machines (various development and test
environments) that sometimes need to be updated. With a large batch I
could spend an entire day nothing but updates. Even worse if I should
have to do it for Linux too.
Aaarrrgh!
