What I have told Rich applies to you too. Look in this post
Although hp is pretty consistent in BIOS update. So before you go ahead with KB4465065, try the hp Support site for a BIOS update.
Applied KB4465065 and am now Running microcode revision : 0x25 (loaded by Microsoft Windows 10 Pro).

@ddelo,
And the winner is...
As you can see, after applying this update KB4465065, my L1DFlushSupported is set at "True" also. Now, does that mean if I run your script again from CPU-info.ps1, my microcode revision is going to change to 0x25 as suggested by @boombastik in a previous post (#180). I am going to find out, because if not what he said about:" in order for L1DFlushSupported to be enabled (True), the microcode has to be x25", doesn't really have any value (sorry to put it that way).

It reconfigured the clone drive bios for the main boot drive to be removable device. Had to manually reset it to boot off the main drive initially set up but then everything worked fine and nothing lost.
