    You may wish to include `-j$(nproc)` on the first `make` command to build in parallel.
 
-4. Calculate the modules size (plus 256 MB for slack):
-   `$ modules_size=$(du -bs "$PWD/modules" | awk '{print $1;}'); modules_size=$((modules_size + (256*(1<<20))));`
+Then, you can use a provided script to create a VHDX containing the modules:
+   `$ ./Microsoft/scripts/gen_modules_vhdx.sh "$PWD/modules" modules.vhdx"
 
-5. Create a blank image file for the modules:
-   `$ dd if=/dev/zero of="$PWD/modules.img" bs=1024 count=$((modules_size / 1024))`
+To save space, you can now delete the compilation artifacts:
+   `$ make clean && rm -r "$PWD/modules"`
 
-6. Setup filesystem and mount img file:
-   `$ lo_dev=$(sudo losetup --find --show "$PWD/modules.img") && sudo mkfs -t ext4 "$lo_dev"; mkdir "$PWD/modules_img" && sudo mount "$lo_dev" "$PWD/modules_img" && sudo chmod a+w "$PWD/modules_img"`
+If you prefer, you can also build the modules VHDX manually as follows:
 
-7. Copy over the modules, unmount the img now that we're done with it:
-   `$ cp -r "$PWD/modules/lib/modules/$(make -s kernelrelease)"/* "$PWD/modules_img" && sudo umount "$PWD/modules_img"`
