First it was downvoted for no apparent reason, then two votes for closure were added on the basis of the question being unclear. Then another vote-to-close was made on the basis of it being off topic. Am I missing something here? Is the site being moderated by people who don't speak English or have enough courtesy to at least comment on the question before stomping on it?
The original text, which I later edited for extreme brevity, was:
Today I booted up my computer, started up WinAmp as my usual first order of business, and then noticed that the media hotkeys weren't working. I closed WinAmp only to be greeted with an error dialog stating that WinAmp had been unable to register my media hotkeys as they were already registered to "another program". I have lots and lots of processes running. How can I find out which programs have poached a given global hotkey? Obviously I tried pressing the hotkeys in question- nothing happened.
I am running Windows 10. Some of the usual solutions require software that does not work correctly in Windows 8+. Rule of thumb; if the site doesn't mention Windows 10 and uses screenshots showing a Windows 7 or Stardock-themed window, then the program probably doesn't work in Windows 10.
