That Windows Update error is a difficult one and in some cases, a factory reset/reinstall was the only solution.
If you've run the System Update Readiness Tool (SURT), it will have produced a log.
This can be found in C:\Windows\Logs then double click on the Checksur one which will open in Notepad.

As for your IE problem, not sure if the Anvi Browser Repair Tool will do anything for you.

How long have you had the IE problem and did it occur after downloading anything and have you tried IE without add-ons ?
