When I try to update to SP1 with Windows Update I get an error code
800F0900 either without the download even proceeding (0%) or very soon
after the download has started. It never has progressed beyond 6% of the
download process without the error. It usually just stops.

Anyone with any insight?

Suggestions?

I have initiated a support request with MS.

Thanks for any help offered.

So far the only suggestion that seems to have any promise is that I
perform and update install from my original installation disk.

Part way through this with the help of someone from Microsoft. There
appears to be at least one corrupted file in my installation that does
not repair with the standard checks that MS does.

When I get something more solid I'll post it to the thread.

I have now been able to upgrade to SP1.

The solution I have used was recommended by MS after multiple efforts to
resolve the error in simpler ways.

The problem seems to have resulted from corruption of mmcico.dll which I
understand is a multimedia file. Through several attempts I was unable
to resolve the corruption.

The end resolution was to perform an in place upgrade installation of
Vista64.

Basically, insert install disk and pick upgrade from the install
options. After a couple of hours I had a functional Vista machine again,
which I walked through all the updates, including SP1.

Now to get all my programs working again. The reinstall broke Nero,
Quicken, and MagicDisk that I know of. Hopefully just a case of
reinstalling them all.

hi all

I apparently got rid of the 800F0900 error on my Vista Home Basic by installing Microsoft's System Update Readiness Tool (KB947821) - http://support.microsoft.com/kb/947821

for months, many updates gave me that error, but after installing KB947821, SP2 installation succeeded at first try.

best hopes
