Can My Pc Run Windows 10

How to upgrade an one-time PC to Windows 10 - free

The Windows ten Technical Preview has been out for some fourth dimension at present, which means that information technology won't be long until the Windows upgrade cycle kicks into high gear one time once more. But if my inbox is annihilation to go by, a lot of readers are however confused equally to whether their existing hardware will allow them to make the leap to Windows 10.

I'grand not surprised people are confused. At that place's a lot of well-meaning yet inaccurate information out there written past people who don't really understand what makes PCs tick. Information technology'south understandable considering tech tin be confusing, and the Windows 10 system requirements throw a few curve balls into the mix.

The basics

OK, and then what do y'all demand to run Windows x? Well, fortunately for us, Microsoft has already published the organisation requirements for Windows ten. Fire that page up considering I'm going to step through the of import $.25 of this certificate.

First thing that should pull your attention is this:

"Basically, if your PC can run Windows 8.1, you're good to go. If you're non sure, don't worry--Windows volition check your system to make certain information technology can install the preview."

This is an oversimplification (we'll get to why in a moment), simply it's a useful one nonetheless. Basically, well-nigh people running a Windows 8/8.1 organization are expert to go. And if yous're not certain, the installer volition run a check to make sure before trying to shoehorn the operating system onto hardware it's incompatible with.

So, what if you lot're non running Windows eight/eight.ane? How can you decide if your hardware is up to the challenge of running Windows 10? This is where the hardware specs come into play.

Here's what Microsoft says yous need to run Windows 10:

Processor: 1 gigahertz (GHz) or faster
RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
Complimentary hard disk drive infinite: 16 GB
Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
A Microsoft business relationship and Internet admission

Beyond the basics

At present if you lot're the sort of person who is a walking encyclopedia of tech trivia, then you might notice how these specs are the same as those for Windows 7. Only at that place is one gotcha that you need to be enlightened of, and this simply becomes apparent if you lot pull up the specs for Windows 8/eight.1 and look closer at the processor specs:

Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2

So in order to exist able to run Windows 10 (or Windows viii/eight.1), you need a processor that supports PAE, NX, and SSE2. Without this, your Windows 10 fun comes to an end.

Microsoft offers a handy primer on what these mean.

PAE gives 32-bit processors the ability to utilize more than 4 GB of physical retentiveness on capable versions of Windows, and is a prerequisite for NX.
NX helps your processor guard the PC from attacks by malicious software.
SSE2 is a standard instruction set up on processors that is increasingly used by third-party apps and drivers.

In that location's more than technical information on these features here.

Testing

So, how can you tell if your processor supports all of this? At that place are a few ways:

Download and run the Windows 8/8.1 Upgrade Assistant. If your hardware is not up to spec, it'll tell you, saving you gigabytes of downloads.
Try installing Windows 8/eight.1. If it won't work, the installer will tell yous earlier y'all wade out beyond your depth.
Download and run a handy utility called CPU-Z. Look under Instructions and if you see SSE2, EM64T (indicates the processor has support for PAE) and either VT-d or VT-x (which is what'southward needed for NX support) then y'all're ready to rock.

CPU-Z
Manually check out your CPU by wading through this listing. This volition tell y'all directly if the CPU supports NX, and it will exist listed as "NX / XD / Execute disable bit".

NX can be a pain in the behind because while your processor might support it, it could be disabled in the system BIOS, which then means having to dig around looking for the on switch.

To install a 64-flake version of Windows 8.1 (non Windows viii) on a 64-bit PC, your processor also needs to support CMPXCHG16b(which also, annoyingly, needs motherboard support, so it can be hard to test for), PrefetchW, and LAHF/SAHF, which adds more confusion. Fortunately, well-nigh people will take this already.

Some caveats

Remember earlier where I said that the "basically, if your PC tin can run Windows eight.1" fleck was an oversimplification? Well, hither's why. In the Windows 10 spec sheet is this line:

"Some PC processors and hardware configurations aren't supported by Technical Preview, including a pocket-size number of older, 64-bit CPUs, and some 32 GB and all 16 GB devices running a compressed operating organisation."

This is a Technical Preview limitation that should disappear once Windows 10 is ready to be unleashed on the world. However, information technology could stump some people trying to examination out the preview -- specifically that "some 32 GB and all sixteen GB devices running a compressed operating system" flake, which refers to devices such as the HP Stream seven that run a compressed version of Windows 8. Some have claimed success in getting the Windows 10 Technical Preview onto such devices, but I wouldn't bother given the chance of something going incorrect.

The virtual machine route

If you lot'd rather play with Windows 10 from the comfort and safety of a virtual machine, you can either install it into something like VirtualBox (these instructions for OS 10 will work on Windows), Hyper-5, or something like VMware Workstation. It all seems to work well as long as your hardware supports virtualization and your arrangement has the grunt to run two operating systems side-past-side.

Yous could also experiment with a native boot VHD, although this is a kludgy and possibly buggy route to accept.

TL;DR

If you're running Windows 8/eight.1 then you're probably skilful to go. If you're not then the installer will tell you. Beyond that, the older your PC is, the more likely you are to be outta luck. That said, testing for compatibility is piece of cake.
