Hi,
The KB2949927 has been replaced by KB3123479(https://support.microsoft.com/zh-cn/help/2949927/microsoft-security-advisory-availability-of-sha-2-hashing-algorithm-for-windows-7-and-windows-server-2008-r2-october-14,-2014),
but after I installed KB3123479, I still failed to install windows-pv-8.2, the errors are same as last email.
If this problem can’t be solved, I have to switch to GPLPV-drivers(http://wiki.univention.com/index.php?title=Installing-signed-GPLPV-drivers
), which works well.
Thanks

主题: Windows 7 signature issues
Hi,
Please don’t hijack old threads.
I checked the signature on 8.2 xenbus.sys and it looks good to me. Are you perhaps running an unpatched Windows 7
that has not been updated to understand SHA-256 certs? (See
https://technet.microsoft.com/en-us/library/security/2949927.aspx).
Cheers,
Paul
Hi Paul,
You said the released drivers are signed, but when I install win-pv-8.2 on windows7 x64, get warning “Windows requires
a digitally signed driver”, below is the screenshot:
When I reboot the system , the system failed to start, “Windows can not verify the digital signature of this file”,
below is the screenshot.
What should I do?
Thanks

Hi David,
I suspect it is turning on testsigning that is stopping Windows Update. You don’t need to turn testsigning on for
released drivers though. They are signed so should just be able install them (clicking through the trust dialog on the way). It’s only development builds that will need testsigning enabled.
Cheers,
Paul
This weekend I set up Windows 10 Pro 64 Bits as a VM (+ VGA Passthrough = GTX 680 harcoded to GRID K2).
I used Xen 4.3.4 on a Linux Kernel 3.19.
The VM is able to boot and works fine.
I installed all PV Drivers for 8.2.0. I added
bcdedit /set testsigning on
before installing all drivers as Administrator (as recommended from INSTALL.cmd file ) .
Unfortunately now activating Windows 10 Pro does not work anymore. I am able to work on the VM but no more Windows Update
:(
Did I do something wrong?
FYI my VM was backed up through LVM system before adding all Xen PV Drivers.
