For HP PCs, the update can apparently trigger BIOS corruption, leading to a failed install, meaning you can't recover the operating system. Per Neowin, HP is introducing a BIOS revision, so it's not clear whether the patch is to blame or it's something on HP's side of the fence.For Lenovo machines, the computer might shut down randomly or black-screen, which is being blamed on power mismanagement.Have you experienced issues with your Windows PC after updating?
