    Yeah, pretty much anything that has the Micro$lop name on it sucks. That's just how they roll. They're a sucky bunch.

    It's pretty clear that the Intel microcode patch locking out voltage tuning will affect all OS's, not just Microsoft.

    It's still up to the desktop/notebook, Motherboard ODM/OEM/manufacturers to give you options to still be able to tune voltage settings. With Microsoft you're screwed. They just follow same paths as Apple... Lock out everything.

    Imagine for yourself... Microsoft as a well known desktop motherboard manufacturer:D The only one in town that lock you out. I wonder how long they would stay in the game:)

    Small form factor laptops / 2in1's like the Surface line don't have any voltage tuning in the BIOS, it's rare to see any BIOS tuning available in anything except enthusiast laptops.

    Microsoft doesn't make any desktop motherboards that I am aware of, so it's hard to say what they would do to be competitive in that market - but I doubt anyone would buy their products if Microsoft doesn't compete in features in any tier of product.

    Maybe that would be a good thing, for Microsoft to make desktop motherboards, and then Microsoft would then be exposed to the required enthusiast BIOS tuning to be competitive.

    Perhaps that would give Microsoft exposure to enthusiast BIOS tuning that would then give Microsoft the freedom to consider adding enthusiast BIOS tuning to their laptop motherboards as well?

    I've wondered for decades why desktop motherboard makers that do so well providing enthusiast BIOS tuning in their desktops have little to no enthusiast BIOS tuning in their laptops, and for the most part they all still have poor enthusiast BIOS tuning support as compared to their desktop motherboards.

    Maybe Microsoft can be the maker to shake up the industry and provide excellent enthusiast tunable desktop and laptop motherboard BIOS's that are similar in both of their product line ups?...

    Nah, that would be about as likely as Intel shipping 10nm desktop CPU's as well as their puny 10nm ULV CPU's... ;)

    It was available through using Throttlestop, but the new microcode blocks it.

    I was referring to the actual visible changeable options in the BIOS GUI interface, not the tuning options accessible from Windows - or in this case inaccessible...

    BTW, has anyone tried reverting to the previous BIOS on their Surface to see if they can restore undervolt?

    All the vendors are getting Intel microcode updates to add to their BIOS's to lock out Intel CPU voltage tuning, so Microsoft isn't alone.

    Will a vendor ignore security problems that everyone else is applying fixes to their BIOS's? I think it should be an option for those few of us that care to get a version of the BIOS without the voltage lockout, but I doubt that will happen from many vendors.

    They should all have made it a switchable option in the BIOS GUI, but that would make too much sense. ;)

    Yeah, and now we can see the fruit from buying a locked system. Flaws with the product can't be fixed anymore. People should start vote with their wallets.

    Microsoft want so bad being Apple. Everything can happen. They tried with phones and failed. But they won't give up their wet dream.

    Microsoft combines Windows and Surface, potentially making it tougher on PC makers pcworld.com | Feb 06, 2020

    Microsoft's latest reorganization reportedly sees chief product officer Panos Panay taking control of Windows and Surface development, as Windows experience chief Joe Belfiore moves to Office.

    And with Microsoft's move to be a major hardware brand we will see their OS will be designed around own products...

    Thankfully my Gram 17 (1st Gen) hasn't been updated with any microcode to prevent undervolting. :cross fingers:

    Guess what, 10th gen laptops will come with the plundervolt mitigation by default so no flashing older vbioses to regain undervolting functionality.

    New unsuspecting users get shafted immediately
