Vladimir EW8BAK in cooperation with Yuri EU2AV adapt it for Windows. Most fresh info will be available here:https://eu2av.ru/viewtopic.php?f=13&t=157&p=907#p907 Github with source code: https://github.com/ew8bak/pihpsdr
Short instruction: first of all you need to install the gtk3-runtime-3.24.31 library, then open the PihSDR_bin folder and run the pihpsdr.exe file, after which the installation will begin. Next, go to the network settings, and create a rule for incoming and outgoing connections.
Instructions are on Github as well. I attached installation file. GTK Windows library you can download here https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer/releases/download/2022-01-04/gtk3-runtime-3.24.31-2022-01-04-ts-win64.exe
By the way, work on linHPSDR on Windows are underway as well
I will inform about progress 
I hope that during or after the port the inherent problems or "bugs" that pihpsdr and linhpsdr can be fixed at the same time and maybe add some features. Maybe being on windows will help with that because of the sheer number of users but I dont think many will sway from thetis. I run pihpsdr linux now becuse other than quisk it is the only other somewhat stable option for our radios on linux. I have had nothing but problems with linhpsdr. I run dual boot machine now and can operate in both OS.
