**Note:** Due to the security problems described in [QSB-091](https://github.com/QubesOS/qubes-secpack/blob/master/QSBs/qsb-091-2023.txt), installation of Qubes Windows Tools is currently blocked. Instead, a text file containing a warning is displayed. Currently, it is difficult to estimate the severity of the risks posed by the sources of the Xen drivers used in QWT possibly being compromised, so it was decided not to offer direct QWT installation until this problem could be treated properly. While Windows qubes are, in Qubes, generally not regarded as being very trustworthy, a possible compromise of the Xen drivers used in Qubes Windows Tools might create a risk for Xen or dom0 and thus be dangerous for Qubes. If you **understand** this risk and are **willing to take it**, you can still install the previous versions of Qubes Windows Tools, which are available from the repositories (version [4.1.68-1](https://yum.qubes-os.org/r4.1/current/dom0/fc32/rpm/qubes-windows-tools-4.1.68-1.noarch.rpm) for Qubes R4.1.2 and version [4.1.69-1](https://yum.qubes-os.org/r4.2/current/dom0/fc37/rpm/qubes-windows-tools-4.1.69-1.fc37.noarch.rpm) for Qubes R4.2.0). Instead of step 1 of the installation procedure listed below, the rpm file downloaded from this location will have to be transferred to dom0 and installed there via the dom0 command

If you **understand** this risk and are **willing to take it**, you can still install the previous versions of Qubes Windows Tools, using the command
sudo dnf RPM-FILE
where `RPM-FILE` is the location of the downloaded file in dom0. This will provide the iso file to be presented as installation drive to the Windows qube in step 3 of the QWT installation.
sudo qubes-dom0-update qubes-windows-tools-4.1.68
for Qubes R4.1.2, or
sudo qubes-dom0-update qubes-windows-tools-4.1.69
for Qubes R4.2.0, respectively, instead of the command listed in step 1 of the installation described below. This will provide the .iso file to be presented as installation drive to the Windows qube in step 3 of the QWT installation.
If you prefer to download the corresponding .rpm files for manual QWT installation, these are still available from the repositories (version [4.1.68-1](https://yum.qubes-os.org/r4.1/current/dom0/fc32/rpm/qubes-windows-tools-4.1.68-1.noarch.rpm) for Qubes R4.1.2 and version [4.1.69-1](https://yum.qubes-os.org/r4.2/current/dom0/fc37/rpm/qubes-windows-tools-4.1.69-1.fc37.noarch.rpm) for Qubes R4.2.0).
**Warning**: These older versions of Qubes Windows Tools will be replaced during the next dom0 update by the current dummy version 4.1.70-1. This can be inhibited by appending the line `exclude=qubes-windows-tools` to the file `/etc/dnf/dnf.conf` in dom0. But this will also stop any further QWT updates - so be sure to remove this line when - hopefully - a new functional version 4.1.71-1 of Qubes Windows Tools will be made available!!!
**Note**: If you choose to move profiles, drive letter `Q:` must be assigned to the secondary (private) disk.
