Hello. I am looking at windows Paravirtualization support and I've seen a few 
projects including:
1) win-pvdrivers by James Harper (http://wiki.xen.org/wiki/Xen_Windows_GplPv)
2) Windows PV-Driver Subproject 
(http://wiki.xen.org/wiki/Xen_FAQ_Drivers,_Windows#What_is_the_Windows_PV_Driver_Subproject.2Fteam.3F)
3) Open Sourced XenServer Windows PV Drivers (https://github.com/xenserver)
Are these 3 projects all different or do any of them refer to the same 
projects? If different, which is the one that is most widely supported and used 
that has future support plans? I am trying to write to XenStore from Windows 
and looking to modify some of these drivers if needed, but dont want to work on 
a dead project.
Thanks.

3 supercedes 2, and 1 is a different set of open source drivers that preceded 
the open-sourcing of the XenServer drivers.

If you want to try to access xenstore from Windows user space then the XENIFACE 
driver in 2 will already allow you to do that via WMI. See 
http://xenbits.xen.org/gitweb/?p=pvdrivers/win/xeniface.git;a=blob;f=WmiDocumentation.txt.
 If you don't want to use WMI then there are also basic read/write/directory 
IOCTLS too (see 
http://xenbits.xen.org/gitweb/?p=pvdrivers/win/xeniface.git;a=blob;f=src/xeniface/ioctls.c).
