Qubes Windows Tools are a set of programs and drivers that provide integration of Windows AppVMs with the rest of the Qubes system. Currently the following features are available for Windows VMs after installation of those tools:
- Seamless GUI mode that integrates apps windows onto the common Qubes trusted desktop
- Support for [secure clipboard copy/paste](/doc/copy-paste/) between the Windows VM and other AppVMs
- Support for [secure file exchange](/doc/copying-files/) between the Windows VM and other AppVMs
- Support for qvm-run and generic qrexec for the Windows VM (e.g. ability to run custom service within/from the Windows VM)
- Xen PV drivers for Windows that increase performance compared to qemu emulated devices
- **Qubes Video Driver** - provides for the Seamless GUI mode that integrates apps windows onto the common Qubes trusted desktop
- **File sender/receiver** - Support for [secure clipboard copy/paste](/doc/copy-paste/) between the Windows VM and other AppVMs
- ***File sender/receiver** - Support for [secure file exchange](/doc/copying-files/) between the Windows VM and other AppVMs

Installing Qubes guest tools in Windows 10 VMs
----------------------------------------------
This will allow you to install the Qubes Windows Tools on Windows 10 both as a StandaloneVM as well as a Template VM and a corresponding AppVM. But some features are not available:
> **Note:** seamless mode is currently not available for windows. Please check the top of this document for the full feature availability breakdown.
1. In the Windows 10 VM, download from the [XEN website](https://xenproject.org/downloads/windows-pv-drivers/windows-pv-drivers-9-series/windows-pv-drivers-9-0-0/) the installation kits for Xen bus (`xenbus`) and storage drivers (`xenvbd`) Version 9.0.0 (two files`xenvbd.tar`and `xenbus.tar`).
2. Use an archive extractor like [7-zip](https://www.7-zip.org/) to extract the contents of the `.tar` files.
3. Install `xenvbd` and `xenbus` by starting the file `dpinst.exe` from the `x64` directories of the extracted tar-files. If during installation, the Xen driver requests a reboot, select "No" and let the installation continue.
4. After installation, reboot.
5. Download the Qubes Windows Tools (`qubes-tools-4.0.1.3.exe`) from [the qubes FTP server](https://ftp.qubes-os.org/qubes-windows-tools/) and move it to `C:\`.
6. Check the integrity of the file `qubes-tools-4.0.1.3.exe`by comparing its hash checksum. This can be done using the Windows command `certutil` on the windows command prompt (`cmd.exe`) and specifying an appropriate hash algorithm like:
certutil --hashfile C:\qubes-tools-4.0.1.3.exe SHA256
And compare it the value to `148A2A993F0C746B48FA6C5C9A5D1B504E09A7CFBA3FB931A4DCF86FDA4EC9B1` (**it has to exactly match for security reasons**). If it matches, feel free to continue the installation. If not, repeat the download to make sure it was not corrupted due to a network problem. If keeps on not matching it might be an attacker attempting to do something nasty to your system -- Ask for support.
> **Note**: this is a workaround for installing the qubes windows tools on windows 10 since the standard way is broken.
7. Install Qubes Windows Tools 4.0.1.3 by starting `qubes-tools-4.0.1.3.exe`, not selecting the `Xen PV disk drivers` and the `Move user profiles` (which would probably lead to problems in Windows, anyhow). If during installation, the Xen driver requests a reboot, select "No" and let the installation continue - the system will be rebooted later.
8. Shut down Windows.
9. On a `dom0` terminal write: *(where `<VMname>` is the name of your Windows 10 VM)*
qvm-features <VMname> gui 1
10. Reboot Windows. If the VM starts, but does not show any window then shutdown Windows from the Qube manager and reboot Windows once more.
11. Now the system should be up, with QWT running correctly.
12. Lastly to enable file copy operations to a Windows 10 VM the `default_user` property should be set the `<username>` that you use to login to the Windows VM. This can be done via the following command on a `dom0` terminal: *(where `<VMname>` is the name of your Windows 10 VM)*
`qvm-prefs <VMname> default_user <username>`
> **Note:** If this property is not set or set to a wrong value, files copied to this VM are stored in the folder `C:\Windows\System32\config\systemprofile\Documents\QubesIncoming\<source_VM>`.
> If the target VM is an AppVM, this has the consequence that the files are stored in the corresponding TemplateVM and so are lost on AppVM shutdown.

Xen PV drivers and Qubes Windows Tools
--------------------------------------
Installing Xen's PV drivers in the VM will lower its resources usage when using network and/or I/O intensive applications, but *may* come at the price of system stability (although Xen's PV drivers on a Win7 VM are usually very stable). There are two ways of installing the drivers:
1. installing the drivers independently, from Xen's [official site](https://www.xenproject.org/developers/teams/windows-pv-drivers.html)
2. installing Qubes Windows Tools (QWT), which bundles Xen's PV drivers.
Notes about using Xen's VBD (storage) PV driver:
- **Windows 7:** installing the driver requires a fully updated VM or else you'll likely get a BSOD and a VM in a difficult to fix state. Updating Windows takes *hours* and for casual usage there isn't much of a performance between the disk PV driver and the default one; so there is likely no need to go through the lengthy Windows Update process if your VM doesn't have access to untrusted networks and if you don't use I/O intensive apps. If you plan to update your newly installed Windows VM it is recommended that you do so *before* installing Qubes Windows Tools (QWT). If QWT are installed, you should temporarily re-enable the standard VGA adapter in Windows and disable Qubes' (see the section above).
- the option to install the storage PV driver is disabled by default in Qubes Windows Tools
- in case you already had QWT installed without the storage PV driver and you then updated the VM, you may then install the driver from Xen's site (xenvbd.tar).
**Caution:** Installing the version 9.0.0 Xen drivers on Windows 7 (a system without QWT - QWT uninstalled) leads to an unbootable system. The drivers install without error, but after reboot, the system aborts the reboot saying `Missing driver xenbus.sys`.
- **Windows 10:** The version 9.0.0 Xen drivers have to be installed before installing Qubes Windows Tools. Installing them on a system with QWT installed is likely to produce a system which crashes or has the tools in a non-functional state. Even if the tools were installed and then removed before installing the Xen drivers, they probably will not work as expected.
With Qubes Windows Tools installed the early graphical console provided in debugging mode isn't needed anymore since Qubes' display driver will be used instead of the default VGA driver:

If you want to retain the User directory between reboots, then it would make sense to store the `C:\Users` directory on the 2nd disk which is automatically exposed by Qubes to all HVMs.
This 2nd disk is backed by the `private.img` file in the AppVMs' and is not reset upon AppVMs reboot, so the user's directories and profiles would survive the AppVMs reboot, unlike the "root" filesystem which will be reverted to the "golden image" from the Template VM automatically.
To facilitate such separation of user profiles, Qubes Windows Tools provide an option to automatically move `C:\Users` directory to the 2nd disk backed by `private.img`.

This can take some time depending on the profiles' size and because the GUI agent is not yet active dom0/Qubes Manager may complain that the AppVM failed to boot.
That's a false alarm (you can increase AppVM's default boot timeout using `qvm-prefs`), the VM should appear "green" in Qubes Manager shortly after.
It also makes sense to disable Automatic Updates for all the template-based AppVMs -- of course this should be done in the Template VM, not in individual AppVMs, because the system-wide settings are stored in the root filesystem (which holds the system-wide registry hives).
Then, periodically check for updates in the Template VM and the changes will be carried over to any child AppVMs.
For Windows 10, the user directories have to be moved manually, because the automatic transfer during QWT installation is bound to crash due to undocumented new features of NTFS, and a system having the directory `users`on another disk than `C:` will break on Windows update. So the following steps should be taken:
- The Windows disk manager may be used to add the private volume as disk `D:`, and you may, using the documented Windows operations, move the user directories `C:\users\<username>\Documents` to this new disk, allowing depending AppVMs to have their own private volumes. Moving the hidden application directories `AppData`, however, is likely to invite trouble - the same trouble that occurs if, during QWT installation, the option `Move user profiles` is selected.
- Configuration data like those stored in directories like `AppData` still remain in the TemplateVM, such that their changes are lost each time the AppVM shuts down. In order to make permanent changes to these configuration data, they have to be changed in the TemplateVM, meaning that applications have to be started there, which violates and perhaps even endangers the security of the TemplateVM. Such changes should be done only if absolutely necessary and with great care. It is a good idea to test them first in a cloned TemplateVM before applying them in the production VM.
It also makes sense to disable Automatic Updates for all the template-based AppVMs -- of course this should be done in the Template VM, not in individual AppVMs, because the system-wide settings are stored in the root filesystem (which holds the system-wide registry hives).

Once the template has been created and installed it is easy to create AppVMs based on it:

It is a good time to clone the VM again.
### Installing Qubes Windows Tools on Windows 10
If the Xen bus and storage drivers version 9.0.0 are installed in a Windows 10 system without Qubes Windows Tools, and QWT 4.0.1.3 are installed after the Xen installation has finished, the Qubes interface works correctly. Files can be exchanged with other VMs, and the common clipboard works in both directions.
The installation of Qubes Windows Tools should **not** be done by using the parameter `--install-windows-tools`or by directly specifying `--cdrom=...`when starting the Windows VM, as this is bound to crash the VM on booting, showing the error `INACCESSIBLE BOOT DEVICE`- which makes no sense, but does happen.
So to get a working Windows 10 system (Standalone or Template VM) under Qubes R4.0, the following steps should be performed:
**to be replaced**
- Install Qubes Windows Tools in dom0: `sudo qubes-dom0-update qubes-windows-tools`. The iso will be the file `/usr/lib/qubes/qubes-windows-tools-4.0.1.3.iso`.
- Copy this file to some AppVM: `qvm-copy-to-vm VMname /usr/lib/qubes/qubes-windows-tools-4.0.1.3.iso`.
- In this VM, extract the file `qubes-tools-4.0.1.3.exe` from the iso, using the archive manager.
- Copy the installation kits of `xenvbd` and `xenbus` Version 9.0.0 (two Zip-files) from the Xen web site and the file `qubes-tools-4.0.1.3.exe` to the Windows system drive (normally `C:\`.)
**end of replaced text**
**new text**
- In the Windows 10 VM, download the installation kits of `xenvbd` and `xenbus` Version 9.0.0 (two files`xenvbd.tar`and `xenbus.tar`) from the Xen web site and the file `qubes-tools-4.0.1.3.exe` from https://www.qubes-os.org/doc/windows-tools/ **enter the final url** and store them on the Windows system drive (normally `C:\`.) In order to extract the contents from the tar-archives, you will need an external utility like 7zip.
**end of new text**
- Check the integrity of the file `qubes-tools-4.0.1.3.exe`by comparing its hash checksum. This can be done using the Windows command `certutil` specifying an appropriate hash algorithm like:
~~~
certutil --hashfile qubes-tools-4.0.1.3.exe SHA256
~~~
This utility supports the algorithms MD5, SHA1, SHA256 and SHA512 (to be entered in uppercase!). The correct hash values can be retrieved from the Qubes website: https://www.qubes-os.org/doc/windows-tools/ **enter the final url**
- Install `xenvbd` and `xenbus` version 9.0.0 by starting the file `dpinst.exe` from the `x64` directories of the extracted tar-files. If during installation, the Xen driver requests a reboot, select "No" and let the installation continue.
- After installation, reboot.
- Install Qubes Windows Tools 4.0.1.3 by starting `qubes-tools-4.0.1.3.exe`, not selecting the `Xen PV disk drivers` and the `Move user profiles` (which would probably lead to problems in Windows, anyhow). If during installation, the Xen driver requests a reboot, select "No" and let the installation continue - the system will be rebooted later.
- Shut down Windows.
- Set `qvm-features win10new gui 1`
- Reboot Windows. The VM starts, but does not show any window.
- Shutdown Windows from the Qube manager.
- Reboot Windows once more. Now the system is up, with QWT running correctly.
For me, this sequence worked for Windows 10 as template VM, and a corresponding AppVM worked too.
File copy operations to a Windows 10 VM are possible, if the Qubes OS `default_user` property is set to the user name used for access to that VM, which can be done via the command
~~~
qvm-prefs <VMname> default_user <username>
~~~
If this property is not set or set to a wrong value, files copied to this VM are stored in the folder
~~~
C:\Windows\System32\config\systemprofile\Documents\QubesIncoming\<source_VM>
~~~
If the target VM is an AppVM, this has the consequence that the files are stored in the corresponding TemplateVM and so are lost on AppVM shutdown.
