If you do paid work with your machine IMO you are batshit crazy to upgrade to a .0 OS release.  At minimum wait for the .1 when the drivers are semi mature, the major issues are gone and whatever critical software you use has been certified stable.

I might toss it on my barebones HTPC to start getting familiar with the new GUI and whatever else though...  Really hoping 10 will be the real successor to 7.

Definitely. The 500 item limit in the start menu for example is a critical issue that will need to be dealt with for a lot of people to be able to use W10 in a pro environment. I have a couple of Celeron boxes that serve as basically glorified Rokus, and I'll try W10 on them first in a few weeks once the Intel IGP drivers have been hammered out. If it's a total disaster it's no big deal at all, I can just reimage them back to W7. They don't do anything terribly important.

I generally use Linux Mint on my work machine because I've got no time for BS on that. I do run W7 on my Samsung S9 though, and I'm in no hurry to mess with that, I imagine it will be a long time before Samsung gets around to updating the drivers for the function keys, touchpad, etc.

Well the upgrade is downloaded and it keeps reminding me that it's time to upgrade. I will just keep using 8.1 until some of the issues are worked out. "We Don't Get Fooled Again".  But I have to say this version is getting more positive comments than any MS OS I can remember. Which is all of them. Hey, I have almost a year so why rush.

Hello fellow Tuxer! I've been running Debian for a long time.
Kimagure:~# uname -a
Linux Kimagure 4.0.0-2-amd64 #1 SMP Debian 4.0.8-2 (2015-07-22) x86_64 GNU/LinuxWere you hit by that nasty CPU lockup bug introduced around 3.16? This machine would go down more than once a day with a hard lockup. Before 3.16, 300+ days of up-time. After, I was lucky to go a week. The bug wasn't stomped out until somewhere past 4.0.2. So far, 4.0.8 has been working well. I can transcode and actually multitask without the kernel blowing a fuse. I actually told a friend that my Win7 machine was more stable than my Linux box. 

As for Windows 10, I am looking forward to DirectX12, but I'll wait until Christmas to upgrade. Hopefully by then they have better driver support, squashed bugs, and changed their policy on collecting "telemetry." Also, hopefully, Nvidia's next gen GPU will be out. My 670GTX with 4GB VRAM is 3 generations behind already.

I just received my notification that my upgrade to Windows 10 Pro from Windows 8.1 Pro is ready to install. I am a little skeptical about driver and program compatibility, unless I can use the Windows compatibility feature for certain programs/software. I have heard mixed reviews on Windows 10, some have issues, others say they have no issues at all. I am looking for some thoughts from those who have upgraded to Windows 10 (especially the Pro Version) to see if it is worth upgrading yet or not. Most of my hardware is new and with Windows Pro, I can disable automatic updates, which I believe will help with driver issues. I am concerned (as another poster stated) about drivers such as those from Schiit for my Bifrost Uber, but perhaps Windows compatibility mode would work if it doesn't work correctly with Windows 10 Pro.

SO basically, I am just looking for some feedback on whether or not to go ahead and perform the upgrade. I plan on making a System Image backup, as wll as cloning my main OS drive, however since all of my Hard drives and SSD's were fried recently and I had to replace them, I really do not have much on this PC yet, and really nothing of extreme importance (or anything I couldn't simply backup).

I also have read that it was fairly easy to roll-back to Windows 8.1 Pro if needed.

I am just looking for thoughts from those who have performed the upgrade as to whether or not to go ahead and make the jump to Windows 10 Pro yet.

Thank you for any suggestions, comments, and/or advice.
