Try a system integrity scan
RUN > CMD > SFC /SCANNOW

Also try using firefox to access the net,then uninstall IE & download to install IE9 again.

You can try rolling back to your previous ver as well.

Well, you can refer to this way:
To repair the .NET Framework you must uninstall multiple versions of the .NET Framework by using the .NET Framework Cleanup Tool, and then reinstall the components.

1. Download the .NET Framework Cleanup Tool:
.NET Framework Cleanup Tool User's Guide

2. Using the .NET Framework Cleanup Tool, uninstall the .NET Framework 1.0, 1.1, 2.0, 3.0, and 3.5.

Note The cleanup tool does not let you remove the .NET Framework 2.0 in Windows Vista or later versions because the .NET Framework is installed as an operating system component.

3. Restart the computer.

4. Download and install the following components:

.Net Framework 1.1:
Microsoft .NET Framework Version 1.1 Redistributable Package

.Net Framework 1.1 SP1:
Microsoft .NET Framework 1.1 Service Pack 1

.NET Framework 3.5 SP1 (this will also install .Net Framework 2.0 SP2 and .Net Framework 3.0 SP2)
Microsoft .NET Framework 3.5 Service Pack 1

5. Restart the computer

6. Visit Windows Update, and then check for and install updates.

HI, actually, microsoft does have an explanation about this error:

Windows Update error 80070020

If you receive Windows Update error 80070020, the cause might be a that program running on your computer is interfering with Windows Update. This problem can often be solved by restarting your computer and running Windows Update again. Answered Jul, 12 2011
