Help with steamgames

I recently went back from windows 10 to windows 7, after installing professional and it crashing after 100+ windows updates, i tried another ISO of it and it seems to have installed all updates fine and everything is working....

EXCEPT STEAM GAMES.

According to a google search this is an actual DEP error, and or registry related.

I have cleared the appcache of steam/uninstalled/deleted the game I've done it all.

The error log shows "StackHash"

If anyone can help me fix this issue with steam that would be awesome!

Also, if you have any idea on how to fix registry errors on a brand new machine that would be great.

I have cookies and some bitcoins to tip if you can help with the registry issue itself and not just "cleaning/deleting" it.

UPDATE: TRYING ANOTHER FRESH INSTALL!

 

This doesn't seem to be directly related to steam itself, after i reinstalled another copy of windows and did all updates steam no longer loads/works.....again...

IF someone finds the exact fix to this stackhash_4c0d error

I will send you $10 in bitcoins. I have tried removing specific updates.. I am no hand uninstalling every single update in hope it works.

 

Try to factory restore your pc to its origial settings, during the reset it should ask if you want to keep your old back ups. delete them all. Another way is there's a way to get into your laptop harddrive and possibly make a whole new seperate partition that isnt linked to the rest. But id recommend trying to get rid of all the partitions on the hard drive then create a new partition and then install Windows 7. Search it up on google, i know how to do it myself.but too many steps to currently explain it all out..
