      @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.

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

            @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.

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

                @dinhngtu We have one Win11 in production, which dodn't install the new tools, running the previous ones.

                We always get:
                ScreenShot 2026-03-18 at 13.38.04.png

                We have rebooted before installing the tools: same issue
                We have run Xenclean before installing: same
                We have run Xenbootfix: same

                Basically we'tried everything. I haven't opened an official ticket yet because the answer here might help others.

                  @manilx Can you check if there's a Copy-XenVifSettings task in Task Scheduler and delete it if it exists report back? Normally it's supposed to self-destruct but maybe something went wrong there.

                      @manilx What do you see when you run this command from PowerShell?

                      schtasks /query /tn Copy-XenVifSettings /hresult ; echo $LASTEXITCODE

                          @manilx Interesting... It's checking for "ERROR: The system cannot find the file specified. -2147024894", which is why it's failing. What if you specified the command this way, with a backslash?

                          schtasks /query /tn \Copy-XenVifSettings /hresult ; echo $LASTEXITCODE

                              @manilx Try installing the .msi from an elevated powershell prompt. That worked for one of our Windows 11 VMs.

                                @conitrade-as Yes, fixed. Thx!

                                The issue on this VM was we were installing as non-admin. All others were admin by default.

                                Good catch

                                  Recent Windows patches also changed the exit code of schtasks.

                                  A new package will be released to address this.

                                    Hello all,

                                    Version 9.1.146 Release of the Windows PV tools has been released.

                                    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 is a small revision to fix issues when installing on certain Windows installations. Only the installer and XenClean were changed; the binaries inside stay the same.

                                    If you're already on 9.1.145, upgrading is optional.

                                    Changes since 9.1.145

                                    • Fixed: Fix issues when installing on certain Windows installations.

                                      Seems that the 9.1.146 version still reports 9.1.145-77 to XO. It is listed as the correct version in "Installed programs" within the guest (Windows server 2025).

                                        @probain Yes, that's expected as there were only changes in the installer and XenClean/XenBootFix, the drivers and guest agent binaries included in 9.1.145 and 9.1.146 are the exact same. As a result, the version information in the guest agent (which does the reporting) was not updated.

                                          Just wanted to clarify something.

                                          Prior to installing xcpng-winpv-9.1.100.0-Release-x64.zip, I ran Invoke-XenClean.ps1 that came with the package.

                                          Is is still true that, in order to install (upgrade to) xcpng-winpv-9.1.145.0-Release-x64, I have to run XenClean.exe again and then run the new installer?

                                          Its just a lot of reboots, resetting static ip addresses etc.

                                            @archw XenClean is not needed when upgrading; it's only needed when switching tools vendor, or when switching from the old XCP-ng 8.2 tools.

                                            The XCP-ng 9.1 tools installer will block installation and indicate an error whenever XenClean is needed.
