Windows 7 SP1 and IE updates fail

[Windwalker]

I have an update issue driving me batty.

SP1 and IE neither will install. Machine is malware free, other updates worked fine. Error of course is generic. Here is what I have tried so far.

1. sfc /scannow (found nothing)
2. temp files cleaned
3. windows repair AIO by tweaking.com
4. Several MS Fixit related to WU
5. Windows Update Troubleshooter
6. reset all windows update comps.
7. Created new user account and attempted from there
8. safe mode install
9. clean boot install
10. disabled/removed AV

The error that sp1 pops is ERROR_SXS_ASSEMBLY_MISSING (80073701)
IE9 install Error code is 800F081E

Try to restore your system a day before the errors occurs..
