UAC and scripts (.wsf)

HI!

I'd like to mark some .wsf scripts as "needs admin rights", so that the
user gets the UAC prompt, when double-clicking on them.

If they were .exe, I could create a .manifest file but for scripts, I
would need a c:\windows\system32\wscript.exe.manifest. Not only would
that be annoying for our customers (putting some file in system32
folder), but it would also affect *all* scripts.

Some time ago, in some Vista newsgroup, someone from Microsoft posted a
solution, but the attachment was missing and I cannot reach him by mail.

Anyone else has a solution to this?

BTW, Java programs have a similar problem. I would have to create a
c:\windows\system32\java.exe.manifest.

Thanks!

Thomas
