I need a bit of guidance, when building a windows network with clients that boot from a single iSCSI VHD disk. whats the recommended way for setting up  a disk (or  file-system ) where individual clients will save their data. I saw an article on http://etherboot.org/wiki/appnotes/cowfor setting up COW devices on linux but I am looking for how this can be done on Windows OS or any other way. I have googled a lot but I cant seem to find anything online. I am using Tiny Pxe Server.  many thanks in advance

Not at all my field of experience but most probably you are not looking for a COW but rather a ROW solution:

That AFAIK is similar to the way you can have in VM's the snapshot or redologs images or delta disks. :unsure:

 

All in all we are going back to the more generic (in the sense of not connected to network booting, etc.) of some kind of "Union FS":

In the Windows world, recent Enterprise editions do have UWF overlays, but disk overlays are (still?) considered experimental:

Otherwise there are some dokan based filesystems, but AFAIK they are all experimental, only partially working or however not at all ready for production, example:
