Windows 7 SP1 failed configuration

Maybe something here to help:
Windows Update error 800f0826

Thanks for that.

Found a couple that failed but when installing from download it says already installed. This is confirmed when I get up list of installed fixes and they are there.

Should I uninstall them and install again?

Looking right back to when I had PC a few weeks ago many updates were done I can see some more failures. Have spent a couple of hours going through all the failures and eliminating ones I could see that later installed.

All others I downloaded individually and tried to install. All came up either not applicable or already installed. Only KB2506212 failed with Not Enough Storage and KB976002 (browser choice) - no link to download.

What are my options now?

Is there any way to tell from a log which item is causing the config of SP1 to fail at 10%?
What happens if I ignore SP1?
Is my only option a complete re install? (after barely a month of hardly any use).

Only restore point is too recent - after last SP1 attempt.

Advice as always gratefully received

You can download, save, and then run the Windows Update Readiness Tool, aka CheckSUR, to see what the issue is in Component Based Servicing, if you so desire. The issue should be showing in one of the logs that CheckSUR creates when it is run -
System Update Readiness Tool for Windows 7 32-bit (KB947821) [May 2011]

The logs are located at and named

Windows\Logs\CBS\CheckSUR.log
Windows\Logs\CBS\CheckSUR.persist.log

You can then attach either of the logs to your reply.


KB2534366 is for Windows 7 32 bit systems, too. Has that update been installed yet ?

How much free space is available on the Hard Drive ?

Have you installed many programs/applications ? If not, the least painful way to remedy this issue is to use the recovery method of the netbook's manufacturer (OEM) to restore the system back to the state it was when it was first booted up.

Then download and save the full, standalone Windows 7 Service Pack 1 32-bit (x86) - Windows 7 and Windows Server 2008 R2 SP1 ( windows6.1-KB976932-X86.exe is the full, standalone for your system )

Ensure all drivers are fully up to date, then manually download, save, then install KB2533552 and KB2534366.
Install them in that order, individually, restarting between the installation of the 2 updates.

Then install the manually downloaded standalone SP1.

Will await your decision on either running CheckSUR or using the OEM's recovery method.

Very helpful advice thanks

I tried to install KB947821 but it keeps saying not applicable for my computer! I have Win 7 starter edition - does it only work for the full editions?

KB2534366 states it is for 64bit systems and windows again says n/a for my system and will not install.

I wanted to try this before resetting so you could review the log file. However if that is not possible then on Monday when I have time I will have to revert to the OEM version and then install the three updates. Is it really just those three if I download the full edition.

I assume reverting to the OEM will lose all my registry entries for my installed programes?

Do appreciate your help here thanks.

PS assume that the full SP1 ( 500mb+) could not be installed possibly containing anything missing?

CheckSUR shows no missing/corrupt content in the logs.
By the way, KB2534366 is intended for Windows 7 32-bit systems, also. Did you click on the link in my previous post to download the update ?
