Windows 10 experiences on cMP

Thoughts on upgrading Boot Camp partition-made Windows 7 to 10 on MacPro5,1? This is my current situation and I want to take the best possible course of action so I can upgrade to Windows 10.

Two observations

Sometimes when moving files or emptying recycle bin there is a pause. This is Defender doing unnecessary malware scans. You can open Task Manager and see it working.

The Start Menu and Cortana rely too heavily on having network bandwidth available. If you download some large file in the background and then try to use either of them they will act like they have crashed. They haven't, they are just having trouble trying to call the servers with so little bandwidth available. Welcome to the always connected era. We need more bandwidth or we need more optimising.

Doesn't work- the reboot into Windows option in the menu bar stays greyed out. As you said, it's a bless problem- stumped how to fix it though.

I'm not convinced that it is a Bless problem. If I understand the man pages correctly, Bless only affect bootability. It would seem the volume should at least be mountable, even if OS X doesn't see it as bootable. If it's not even mountable as you say, then it would seem something else is going on. Sorry I cannot be more help.

True and bless issue should go away with a reset. I think a clean install of Yosemite on a separate drive and test out what start up disk control panel does there. If it still doesn't work then the issue is not software. It's firmware or hardware.
 
Ok folks, after four days of no crashes or BSODs I can safely conclude the USB 3.1 card was responsible for the instability.

I have taken that out and everything is superb.

I also replaced the Magic Mouse with a Logitech Performance MX which is typically known as the best mouse in the world for the last five years. It is half price now because the Master MX is replacing it. Works fully in El Cap too.

Edit: it appears Steam might cause crashes too. See below.

If you're gonna buy games go to cdkeys.com. Crazy discounts. They send you the activation codes and you download from established distributors like Steam, Origin, etc I can't believe how much money I would have saved if I found them earlier.
 
Reinstalled Steam. Return of the BSODs :eek:

Finally learned how to debug. The crash log says the new crashes are occurring in the CPU.

Going to see what happens if Steam doesn't launch or run at all. I also set Windows 10 to run in power saving mode.

So all in all Windows 10 on cMP is not yet recommendable for normal users?

I'm just now installing Windows 8.1 on my cMP, better not yet upgrading to Windows 10?

That's not what I'm saying, it's a new OS and there will be crashes and conflicts. I'm just listing where those issues might occur in case it happens to anyone else. My experiences might not occur in someone else's cMP. The cMP itself is a very basic machine by modern standards even if it has the name 'Pro' on it and dual CPU sockets.

I'm pretty certain Windows 10 isn't crashing on its own. It's the software and hardware combination that I am installing on it. Once the drivers and apps are mature I'm sure things will be stable.
 
Without Steam running at all, even in the Taskbar notifications area, stability has returned again. So I suspect the application isn't optimised for Windows 10 and in particular dual CPU systems.

So I need to do a social experiment and call for help from guys like @RoastingPig and others who have dual Xeon systems. If you have such a system configuration with Windows 10 and Steam, please do feel free to tell us your up times and any crashes, BSOD or errors you observe.

Further experiments have failed to eliminate the problem, mystery only deepens....
USB Yosemite installer: Windows disk appears in Startup Disk
USB external HD (clone of primary HD): ditto
SSD: still not appearing
Primary HD: still not appearing. These two disks are in a homebrew fusion setup (SSD as startup but User directory on the HD) which may or may not make a difference. The Windows disk was appearing on the desktop at first.
Tried swapping drive sleds around- no difference.
Disk Utility repairs after starting from the USB drives- no difference..
 
I saw that the new bootcamp 6 has a win10 usb3 driver, maybe that will fix your problems?

If your usb3 card is same as one of the supported apple chips, cant you extract the driver from bootcamp 6 and install it on your cMP.

Nothing to do with my card. Anyway that problem is eliminated. I just need to confirm Steam is giving problems. I should know with one more week of testing. First I will run the system without Steam for three days. And then I will start running Steam again. If you have Win10 and could run Steam on it to give me some feedback I would be very grateful.
 
So, finally i installed Windows 10 on cMP. :D

I installed a fresh Windows 7 Pro 64 Bit, and it was a PITA to get all 280 Windows updates downloaded and trouble to get this little upgrade button appear:
Button.png
Although I installed all updates this button did not show up first…

My workaround
- I removed all SSDs/HardDisks/Apple SSD blade except the one for the Windows install
- Fresh install and activation of Windows 7 SP1 64Bit from DVD
- Installed Boot Camp 5.1 drivers
- Installed Nvidia driver 355.60 for Windows 7/8/8.1.
- Installed Windows 7 drivers for Caldigit FASTA 6GU3 and FASTA 6GU3 Pro USB3/eSATA cards.
- Did all the necessary Windows updates (I hate Microsoft servers…)
- Deinstalled and reinstalled Windows update KB3035583 (Windows 10 installer) to force the Win10 upgrade button.
- Forced Windows 10 download (CMD: wuauclt.exe /updatenow)
- Upgrade to Windows 10 without problems
- Installed Nvidia driver 355.60 for Windows 10
- Did all the necessary privacy settings.

To my surprise Windows 10 is running perfect with Boot Camp 5.1 drivers, did not need to reinstall them. All hardware included the Caldigit cards are recognized. For the moment all fine.

And if you are used to Windows 7 you don't have user issues with Windows 10, my opinion.

Thanks. I now have two days up time without Steam running. If it was running I would be lucky to have a few hours. Within a week I will have the conclusion and report it to Steam. Until then I can just play Witcher 3 in GOG games, FIFA in Origin.
 
If you ever get this nice message when restarting or shutting down it means the Nvidia drivers need to be reinstalled.

I have a 2009 Mac Pro, 5,1 quad-core, upgraded with new processors. I had Win 7 running on a separate HD. So I figured I'd do the upgrade to Win 10. What the heck. So, I upgraded to 10 via the MS site while in Win 7. It took a while, but once done, it worked fairly well. But my apple mouse wouldn't scroll within a window (it wasn't recognized as a Apple mouse in the Device Manager). So, then I went back to OS X, opened boot camp, downloaded the new Win 10 Bootcamp to a thumb drive. Then restarted in Win 10, and updated Boot Camp via the thumb drive. It seems that it works fine. Now, I haven't tested everything and actually only a few things. I did find that unless you select the Mac drive as the startup drive in Boot Camp, then booting into OS X seems to take a little longer.

That's why I never select Boot Camp drives via Startup Disk. I always choose Windows drives via option boot.

Once you've don a PRAM reset OS X will boot fast again.

Thanks!

Reverted back with a Winclone Windows 8.1 Pro x64 backup! I'm (for now) done with these upgrade issues.

It's not the applications that are crashing, but that Windows 10 upgrade KILLED most (90%) of my applications.

Fed up to trial-and-error this! The TP worked perfectly in a VM, but the real thing is a nightmare for my setup.

Later I'll try the "remove all hardware" method (exept PCI cards) like SSD's and move my Windows SSD to bay #1-4.

Cheers
