Tried every fix I could found, Windows Update still searches for ever

(windows 7 pro SP1 64bit)
Hi everybody,

this is my first post here.

2 weeks ago, one of our business laptop had some problems with windows update.
I started by the usual, MS fix-it, hot fixes, reset update history...name it, I have done them all...
Result is always the same :

After trying every damn possible solutions i could find, I said f** it and I reinstalled windows after performing a deep format on the PC's hard drive.

I thought this would do the trick, as always, but ehh... (everytime I install windows 7 Pro sp1, I run these two, one at a time - no internet - and i reboot between each of them : "1-Windows6.1-KB3138612-x64.msu" and "2-Windows6.1-KB947821-v34-x64.msu")

Those always worked like a charm, they push windows update to find his first 200+ updates batch in less than 3 min. I love it and I always use it when I freshly install windows 7 pro SP1.

And actually it worked, I could download and install the first big batch of updates as usual... but then after rebooting...

We are right back where we started.

Help me please, Im gonna throw this fu***er PC out my window.

PS: i also followed the steps before creating a post : SURT searched for updates for 1 day and a half so i closed it, and SFC /scannow didn't came up with any errors. I am also not able to upload my CBS.zip file (404 not found) so I uploaded it on GoogleDrive :" CBS.zip - Google Drive "

Thank You
