Removing UPX protection? (compressed file)

Actually I opened the file in Exescope to view resources, and Exescope told me that the .exe was compressed. So I sniffed the .exe in PE Tools, an it told me that the protection was.

Is there a way to automatically uncompress/unprotect the file, or is it a manual job?

The file in question is actually a patch installer, so it's purpose is to update other files.


Thanks.
