Last night i installed BitTorrent and tried to download a software. Some how i changed the settings and result came out that no program can open. Each program try to open with BitTorrent. I wanted to remove/uninstall/delete BitTorrent but failed. Even cmd or regedit do not open normally. All the time same error message came out.

The only solution i see over internet is https://filext.com/faq/broken_exe_association.html
But it is not working for my case.

I searched for internet and no solution there. i just found a solution myself. I entered my win 7 on Safe Mode. I was able to delete BitTorrent. I logged into my windows on normal mode and everything is fine now.
