Windows update error 80071A91 also 80070643

Toshiba Satellite L755-5350

This is a clients laptop who first noticed that Windows updates on shutdown would fail and restart, revert, restart. This happened on every shutdown after that.

Started with this -
No updates can be installed shows error 80070643
Re-installed with Toshiba System Recovery but same error - 80070643. Re-imaged system back to configuration was as I first found it.

Reboot 3

Reboot with a checkdisk due to a posting I read on this forum today had tried this (Win 7 updates failed - 80070643 and 80071A91). Looks like it has helped. This wasn't on my radar. Next time WUpdates throws a hissy fit I'll do that. Because it's free and takes one variable off the table.

After a manual update check only 11 were available and chosen to update. Approx 10 updates were in pending stage at the end of the updating. All 10 resolved after reboot.

Update KB2862330 failed with "Error details: Code 8020000E"


***
Reboot 4

Installed 2 updates KB2862330 and KB2888505

Again Update KB2862330 failed with "Error details: Code 8020000E"


***
Reboot 5

Rebooted with no Windows errors. one update avail.

Again Update KB2862330 failed with "Error details: Code 8020000E"

Hat tip to Golden for his suggestion to manually apply the KB286330 Update. Applied the Win7x6x file here (http://www.microsoft.com/en-us/downl....aspx?id=40579).

Big Hat Tip to DayGloScooter for reminding me about CHKDSK which I think is what corrected the update errors.

(Win 7 updates failed - 80070643 and 80071A91)

No errors upon reboot!!! Manually checked for important updates, none available. Set updates to install automatically and going to call it a day.
