Does it support windows 10?

i used the windows 7 and 8.1 drivers on the dsic, just remember to run it from the Cdf not run t he software as all you need is the driver not the software.

Does this come with a low format plate?

This Wireless Adapter does come with a low format plate. I don't use mine because it is to small to fully seat into my PCI Express x4 slot. I have a Full Tower. This should work just fine for small form factor PCs.
