In this tutorial, we will look at how to install Windows 11 on Proxmox.

The process to install Windows 11 on Proxmox is extremely similar to most other virtual machine installations on Proxmox. The main difference is setting up and configuring TPM, which we will walk through below. It’s always a good idea to ensure that Proxmox is up to date, which as of the writing of this article is v7.3-6. Also, please check out our tutorial on GPU passthrough if you’re interested in configuring that!
