Wiping your Windows recovery partition
I recently replaced my Windows 10 LTSC installation with a stock(er) Windows 10 Pro install, one thing I noticed was an additional partition automatically being created. This partition was helpfully labelled as a recovery partition, and took up 512MB of ever so precious space. I did a bit of research into the matter and found out it wasn’t strictly necessary, and personally when it comes to recovering an operating system I have no qualms performing a clean install.
So, to remove this, first launch an admin command prompt (search for
cmd in your start menu, right click, run as administrator) and run the following:
diskpart list disk select disk 0 list partition select partition 4 delete partition override
in the example above, our recovery partition is #4
You can now expand your system partition into the empty space.
diskmgmt.msc, right click your system partition, then extend volume.
