I completed a technology article about that: most fixes are done, together with benchmark updates.
On Linux it's automatically applied as long as you have the ucode package. I'm not sure about the Windows version, but it seems to be handled via Windows Update. For firmware updates related to ucode, you'd need to update your BIOS, so your vendor must provide an available update for download and installation.
Read the report that the patch actually hurt the chip's performance by up to 28% in rendering, compared to a purely theoretical risk, indicates the fix is more damaging than the problem soon after the CPU will consume nearly all its power to protect just a tiny fraction.
