I haven't tested any games as of yet, but removing avast free antivirus has solved the issues of my applications freezing and applications not opening. I have restarted the pc several times opened many applications and ran them and so far all is well, as for games i to hace watchdogs when i have time i will run the game and see if any issues come back. I have also posted the problem on the avast forum. I would love to know why hasn't avast fixed the issues with 2004?
I did what someone here suggested remove avast using the removal tool and then testing all my applications. Windows 2004 is not stable at all, it should not have been released.
It looks like all of our whining (to our English friends that's winging) has had a impact on the guys at Microsoft! 2004 is not available now. My laptop message says "feature update to windows 10 is on the way, version 2004." They took down the defective download. So roll back and keep checking for the updated version. Maybe for those with 2004 on their machines a patch is available.
