I'll have to update group policy and check that out, would be a time saver. Everything I use is an Enterprise level of some kind, using EDU in production right now, and Pro/Enterprise evaluation in the lab.

I was looking at running a post imaging script to prevent some of the bloat, but a GPO might be easier.

You can use Windows ADK to customise the installation media and build a custom ISO. That file can then be placed on your ISO SR. The GPO is especially effective when combined with a custom ISO built using Windows ADK.

I have tried this myself and it’s very effective doing it this way, the Windows ADK tool is very powerful but will require time to learn. Will save time with all of the extra installations, if you use a custom ISO.

When it comes to the feature to disable time sync.
If you had previously installed a version of PV that did not have it, then install the newest version and enable the option to disable time sync.

Should that remove it or do you have uninstall the old version first and install the new version?

[dinhngtu]

@tsukraw There's no need to uninstall the old version, the upgrade is enough.

The feature to disable time sync is also just a convenience shortcut for setting the TimeSyncMode value in HKLM\SYSTEM\CurrentControlSet\Services\xenagent to a DWORD of 0. You can set it manually or through Group Policy if you wish. (In fact, GPO might be a better solution on domain environments)

Hello all,

Version 9.1.145 Release of the Windows PV tools has been released.

(Despite the name, it's still signed; I simply dropped the "Signed" moniker)

Download the latest release here: https://github.com/xcp-ng/win-pv-drivers/releases

It will be integrated into the XCP-ng built-in tools ISO after a test period of 2 weeks.

This release brings the new XCP-ng Standard VGA Display Driver as well as multiple bug fixes to all Windows drivers and guest tools components.

Changes since 9.1.100

• Improved: XenClean is now a single executable that's more convenient to use.
• Improved: Better uninstalling of existing drivers.
• Fixes: Automatic time sync is now disabled by default on new installations. NTP sync with W32Time is recommended instead.

Install went with out issues on my homelab pc windows 11.

@dinhngtu Upgraded from previous tools (big jump from citrix was already done ) @home and @office a dozen Windows11 and Windows Server 2022.
No issues.

We noticed that using the XCP-ng Windows PV tools brakes some functionality of the shared clipboard. On a fully patched XCP-ng 8.3 host using Xen Orchestra 5 (actually the 6.2.2 build, but the v5 interface) allows only to copy the clipboard from the VM to the browser, not the other way around.

[dinhngtu]

@conitrade-as There should be a fix for that in 9.1.145. Could you try it?

[conitrade-as]

@dinhngtu That indeed seems to work. I just realized, that this is a timing issue as well. Sometimes the copy&paste works after a slight delay, where the console seems non-responsive (e.g. cannot move the mouse cursor). After something like ~15 secs things work as expected. For subsequent copy&paste operations the delay seems to be much lower.

[dinhngtu]

@conitrade-as Sounds like a problem somewhere in the clipboard stack, I'll look into that.
