So im participating a CTF competition, wanted to do the forensic challenge, and the challenge is a windows registry forensic challenge, but instead of using regedit or "open with" option. I accidentally run the registry file. And now my pc is broken, please help me to fix this

There is no way for anyone here to know what changes that registry file made to your registry, the best option to undo any changes to the registry is to perform a System Restore to a date before the registry file was executed, that process will restore a previous working version of the registry.

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt... etc.

Go to Troubleshoot - Advanced Option - System Restore

Check to see if you have a restore point you can go back to
