Windows Update not working, ERROR CODE: 80070027. Windows 7

Question

Hello:

I have been experiencing the following problems:

1-Unable to install updates since KB2982791 on 12 August 2014 (of a total of 8 Security updates and 4 Windows updates performed on that day).

When running Windows Update, program says it needs to update itself, but always ends giving ERROR CODE: 80070026.

There's no failed updates shown on the Update History section either.

2-All Windows Troubleshooters also seem to fail.

-Could this be related to an issue with Microsoft Framework 2-3?: I had to uninstall then reinstall the latter, in order to update drivers for a mouse, as instructed by their supprt team. Ever since, all Troubleshooters seem to have failed (''unable to perform requested task'').

-There is no problem with anti-virus real-time protection. Windows still won't update when its off.

Any help will be greatly appreciated. I am a bit confused, since have seen different solutions listed for this issue (Error 80070027) and most are quite old (2009) or refer to Vista OS. Thanks in advance!

Kind Regards

Please provide a copy of your System Information file. Type System Information in the Search Box above the start Button and press the ENTER key (alternative is Select Start, All Programs, Accessories, System Tools, System Information). Select File, Export and give the file a name noting where it is located. Do not place the cursor within the body of the report before exporting the file. The system creates a new System Information file each time system information is accessed. You need to allow a minute or two for the file to be fully populated before exporting a copy. Please upload the file to your OneDrive, share with everyone and post a link here. Reports in normal mode preferred. Please say if the report has been obtained in safe mode.

Please upload and share with everyone copies of your System and Application logs from your Event Viewer to your OneDrive and post a link here.

To access the System log select Start, Control Panel, Administrative Tools, Event Viewer, from the list in the left side of the window expand Windows Logs and select System. Place the cursor on System, select Action from the Menu and Save All Events as (the default evtx file type) and give the file a name. Do the same for the Applications log. Do not provide filtered files. Do not place the cursor in the list of reports before selecting Action from the menu. Do not clear logs whilst you have a continuing problem.
