    I have been troubleshooting an issue with Windows for about a year now. I installed 8.1 Pro on my 2014 15" rMBP and it ran incredibly hot. My fans were constantly running and blowing hot air out of the machine, obviously. I thought it might be a bootcamp issue, formatted my drive, installed OS X fresh, installed 8.1 fresh, made sure not too many apps are coming up at startup, pretty much everything you can imagine to keep the processes to a minimum. Still though, the fans are going like crazy. Windows forums are no help, they told me to turn off un-needed processes, which I already did, then they said that it was a faulty issue with MacBooks running Bootcamp can only access the better graphics, but that doesn't make the machine run hot in OS X. I was curious if the upgrade to 10 pro would help, did that, I like the system better than 8.1, but it is still crazy hot! I noticed that my girlfriend's HP Pavilion was running hot on 8.1 as well, updated hers to 10 pro, made sure processes were at a minimum, and even without running any apps at all, hers runs super hot as well. What is going on? When I run OS X my battery lasts for an incredible amount of time even while running the better graphics card, but bootcamp with 10 pro only lasts about 2 hours tops. Also the HP only lasts for about 1.5 hours. Any ideas?? I can send screen shots of whatever to help solve the issues.

    I can't help you with Windows 8.1. It's a thermonuclear-based OS, and I couldn't wait for Win 10 to hit the interwebs. I also don't use BootCamp - I don't rely on Apple to provide Windows-based support, I use either PCs or Parallels Desktop. It's not you, or others in this Forum - Windows runs hot on laptops and desktops, and I have oversized cooling units (about 1.5 tons per 1000 SF) for my four offices (and we're in the Pacific NW, where the temp really never gets that hot!) because of the PCs that run in my offices.

    I've noticed that Parallels Desktop 11 on Macs is about as zippy as native Windows for what we do, and I like the extra layer of granular control over the virtual machines that PD (and Fusion) provides.

    'Nuff written. I have two VMs, both 64-bit Win 10 Pro with 128GB/8GB 2-core configs on my late-2013 i7 rMP - one runs hot, the other doesn't. They're clones of a master VM. The one that doesn't run hot is running the latest 1511 Build. I get roughly 6 hours of battery life on my Mac with the cooler VM running, about 2 on the untouched "hotter" VM. I turned off all of the unnecessary networking, updating (only in the Pro versions), Privacy, and Notification options that I don't need. I didn't futz with Services.

    I made the above changes to one of my PCs, a newer HP laptop with a spec sheet like 256GB SSD/16GB/2.6 i7. Battery life went from about 2 hours to 6 hours. I've been using Windows since v 3 - a long time - and Windows likes being networked or it complains a lot. MS offers a means to disable services in its Settings Control Panel - disabling everything I don't need cut the battery drain quite a bit.

    Also, delete the Win 10 apps that make no sense for your workflow, like for me the Windows Phone/Phone Connector/Groove Music/Xbox/Weather/etc./etc./etc - and they won't be pinging your network and beating up your battery. The OneDrive app can be looking for files constantly too - if you don't use OneDrive, disable it or remove it.

    Windows runs much hotter than OSX. Windows-based PCs can run cool, so I can only conclude it's mostly due to Apple's drivers. I don't think it is using all the aggressive power-saving features available. The only option is to go into power settings and reduce the maximum CPU frequency percent on battery to something lower. That would force the CPU to stay cool.

    Windows just has poor power management. My CPU frequency is usually lower on Win10 than OS X but will have 40% of the battery life of OS X. I believe it's related to the GPU power management under Win10 that causes the poor battery as well as high temperatures!
