[Code-Crunchers] Tiny PE: now 274 bytes

If we ignore Windows 9x completely, then we can shave off more bytes from the main part.  However, apart from the 2 extra bytes in the header, I haven't found anything else that's safe to use.
If someone can crunch the header further, I'd really like to know how that was done.

I saw that someone has got it smaller but not made public yet, so
they might already be doing this. Anyway, how about instead of
using winexec, just reuse loadlibrary() to run a downloaded .dll

If DAV/SMB sharing is to be considered then just loadlibrary() the
remote dll to do a download and exec in one call.

Well, you do got the source, although in binary form...
Peter, you expect people do OCR on your BMP? :)
