I finally manage to upgrade windows 2008 server from 0.9.1[12] to drivers.

For all my tests I started by doing a snapshot of my windows 2008 system disk and working with the snapshot instead of the live image ... it allow to be sure to be able to restart with a sane situation ....

I first tried the uninstall (with the .bat provided by james on his website) and then installing new drivers while after rebooting without /GPLPV. At next reboots booting either with no flag or with /NOGPLPV or /GPLPV always lead to blue screen with 0x07 error.

I noticed that when I rebooted with drivers 0.9.1x installed but without the GPLPV flags all xen devices but the xen pci where with a yellow question mark (which is logical).

So I in the device manager I suppressed the all that xen devices including the xen pci and always asked Windows to remove the driver as well.

Once it's finished I restarted the computer, run this part of the script
REM stop and remove shutdownmon service
net stop shutdownmon
"%ProgramFiles%\Xen PV Drivers\ShutdownMon.exe" -u

REM remove XEN from Program Files
rmdir /q /s "%ProgramFiles%\Xen PV Drivers"

and this one:
REG DELETE HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318} /v UpperFilters /f REG DELETE HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318} /v UpperFilters /f REG DELETE HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E97B-E325-11CE-BFC1-08002BE10318} /v UpperFilters /f

Then I installed the new drivers restarted 2 time in /NOGPLPV just in case.

Now I am enjoying windows 2008 server with up to date GPLPV drivers.
It seems that this version of drivers are quite good because I am able to get most of the native speed from the hard drives (which I wasn't able with 0.9.1x), the only drawback is that cdrom isn't showing at all (like I reported already in XP).
