I have created a portable version of deskwin as I sometimes need to work with virtual desktops and would like to that, as well, from my USB drive.
I did put a beta label on it as it has only been tested by me, the beta refers to the portable version.
The portable package is built upon John's PuttyPortable and should confirm to porttableApps.com
Once the beta has been tested I'll create a nicer splash screen and release it in firm revision.
I hope that anyone can gain anything from it.
