Microsoft's latest Windows 10 and Surface updates are causing major headaches

Windows 10 has undoubtedly been a significant improvement over its predecessors, but the latest operating system from Microsoft isn’t without its issues.

Over the past several days, a variety of substantial issues have cropped up for Windows users, most of which appear to stem from recently released firmware updates.

Based on the timing and frequency of Reddit posts regarding the issue , this has been affecting Surface users for at least a year.

TechRepublic explains that the throttle-lock is seemingly being caused by “an Intel CPU flag called BD PROCHOT (bi-directional processor hot),” which tells the CPU to throttle down to lower the system temperature.

BD PROCHOT can be found on plenty of devices, but as the site notes, the timing of the reports (which have picked up in recent days) seems to indicate that new firmware is to blame for the recent rash of complaints

“We are aware of some customers reporting a scenario with their Surface Books where CPU speeds are slowed,” a Microsoft spokesperson told TechRepublic .
