There is currently the exe tag, which is about .EXE files under Windows, which theoretically covers the
New Executable, and
Portable Executable formats.
There are already several questions relying on this tag.
Many specially flavoured PEs have different extensions in standard: DLL, SYS, OCX, SCR, CPL...
But its tag-wiki immediately mentions PE-specific characteristics like resources, etc..
Do we want to keep a tag that will likely be mostly used for PEs while it theoretically covers 2 other formats?
