I have never edited the registry on this laptop and I absolutely DID NOT remove any registry keys for WinZIP. I have not touched the program. I don't remember installing it to begin with and I don't use it. I went into my uninstall to remove another program and was looking for anything else I might want to get rid of and noticed WinZIP and decided to remove it. WinZIP possibly came with the laptop when I bought it but I don't honestly remember.
