no difference between windows 7-10 filing system, only capabilities
also, with bugs with modding other games, or other games in general, I'm using the latest windows 10 version with no probs (Starbound, MC, Skyrim, not tested Terraria yet)
On the surface level yes, but an Operative is like a iceberg in the sea. There is a lot below the sea that most PC users have no knowledge about

But for Windows 8 to be like 7 and 10 you have to completely ignore Meatro (the Tablet menu interface)

No, it's games Brought on Microsoft's Store aka "Games for windows 2.0" which should had stayed dead and gone!!
But Frankly,
@✩ITzzPixelHere✩ have some issues, and didn't give me any specifics nor clues for me to work from to solve it

and certainly not the PC system itself. So i could figure it out what the issue is myself and then fix the issue.
I'm an IT Technician, and asking what Operative is the bog standard question. as it's kind of asking what language are you speaking

"hva' snakker du om?" "was spricht du?" "what are you talking about?"
But also Windows xp-10 was Given as an Example, as Windows is the Common OS
as many people don't understand if you ask them what Operative System they are running, unless you mention Windows or mac...
if (s)he had sad Mac or Linux, that would explain what the issue is; incompatibility with Mac and Linux since i don't have either of those.

if (s)he didn't say windows 10, i could rule out Windows store entirely
I have yet to run into something that really made feel like i need to upgrade to Windows 8 or 10.
as i have a Xbone Controller working on Windows 7, yet Microsoft stated it required Windows 10...

with the only real difference is what Direct-X Microsoft Limits you do have (based on your OS, not the hardware)
and how large HDD or SSD drives the Motherboards Bios can read, without a firmware update.
but also since i have Windows 7 pro, 64Bit - i can use to up to 192 GB Ram of System Memory. (CPU is limited to 64 GB)
but i don't have a reason to go above 32GB yet.
Sure, if i had Windows 10 i could squeeze out a few more FPS, yet by disabling Windows 7's Aero can yeld slightly more.

and i can Run Doom(4) on 1080x1920x60fps @ Max settings with a GTX 1080 on Win7

what can Windows 10 do that i can't get my windows 7 to do?, what spy on me? wait how is that even a good thing?

the new Skylake CPU?, that is a downgrade to what i currently have... before we look at losing 24 Pci-e lanes by going down to the default of 16

and No
@NexusTheBrony, this isn't directed at you

, it is entirely directed at Microsoft and Intel.
as they are pushing the limit in reverse...
Also several modding tools don't work on Windows 8/10, like the png to Xnb converter tool (since the Dev kit needs Windows XP, Vista or 7)
Which is totally arbitrary, but also Microsoft stopped support for it not that long after Windows 8's Launch.

and that is the Program-engine Terraria runs on.
