No that is untrue. It only requires a chip that supports either AMD-V or Intel's VT-x and yes there are some Core 2's that do support it.

This comes from my experience in running Hyper-V on a Nehalem i7--ie the First Gen Core i7s.

^ thanks for all the replies... I was mainly asking for Windows 8's version of Hyper-V... Did some more research and apparently, judging by the CoreInfo tool, my CPU doesn't support SLAT which will be required to run Hyper-V on the desktop. :(

I was hoping to get rid of VMware, I guess I won't be able to.

I think I've read somewhere that Hyper-V will require Sandy Bridge CPUs to function properly... is this a requirement only for a specific feature, or will Hyper-V not run at all on Core 2 CPUs?

The feature that Hyper-V on Windows 8 *client* (not Server) requires is Second-level Address Translation (SLAT) and is specifically required by the RemoteFX-enhanced VM client in Windows 8 client. However, it is supported by Sandy Bridge CPUs above the Pentium G series (basically i3 and later).

However, i3 is silly-cheap.

Your BIOS also has to support DEP on Server 2008 R2. Normal server 2008 will work without. Little ****ed about this atm. My i7 Supports it but my Intel Motherboard has DEP disabled.

And there is no switch to enable it?

Conversely, the SLAT requirement does not exist for either Server 2008R2 or Windows 8 Server - I've run both on an E3400 (Celeron DC) on a motherboard with the *desktop/CSM* G41 chipset - Hyper-V works in both OSes just fine.

I'm upgrading to i5-2500K; however, Hyper-V is not why.

VMware Workstation 8 also works just fine in Windows 8 Developer, so that should be the case for the upcoming Consumer Preview as well.

It's not a Hyper-V core requirement - it's a requirement unique to the Windows 8 client.

Hyper-V itself normally has no greater requirements than Windows Virtual PC 2007 did - AMD-V or Intel's VT-x support. Windows Server 2008 and higher keep that requirement.

In the case of VT-x, most Core 2 CPUs and derivatives do support VT-x - down to, in fact, the Celeron DC E3xxx.

The additional requirement is due to an addition to the Windows 8 client for Hyper-V hosting (RemoteFX support) that Windows 8 Server does not have. That restricts the support to the Core i-series (i3 and up - both first-generation and second-generation).

you could check the above link for core2duo cpu's and check if it has VT-x feature.

ermm get rid on VMWARE Workstaion .... well you could use Virtual Box and use the Virtual Box PHP (webadmin) does just about the same job as VMWares Free Server (until they canned it) ,, and does way more then the VMWare Player ;P ...

i can run Ubuntu, XP, VIsta, Server 2008 R2 and Mac OSX 10.7 all 64 bit in Virtual box for testing ..i run this all on a lowley system Intel Core i3 530 2.9Ghz, 16gb kingston HyperX (grey) ram at 1.5v 1333mhz, Gigabyte GA-H57M-USB3, Corsiar Force 3 120Gb SSD (Boots Windows Server 2008 R2, have a IBM ServeRaid MD1015 (LSI RAID Card) that runs 2x 1Tb Western Digital Cavier Green Drives 64mb Cache each in RAID 1..

IIS 7.5, PHP 5.3, MySQL 5. and TVersity on base OS ... i have 2 server r2 VMS, 1 has Exchange Server and ADS, 2nd has Sharepoint

PS this is TechNet Professional Licenses only using to learn some server setup and admin things ... may swap to a Linux Base OS thou unsure what to do lol

yes my system spec is cheap its cheerfull does all i need to store and share files and for messing around, PS all runs 24/7 on a 350 Watt PSU!

... LAST time i tried to use Hyper-V a word of waring on Intergrated Intel HD Grahpics once the system rebooted from Installing Hyper V, I No longer had a Video OUTPUT.. moving the mouse made the screen come back but it randomly flickered on and off very fast ... making the system unusable ..so i think hyper-v dont like Intergrated GFX in processors report on Technet by some one else http://social.techne...b4-1fd526cd6542

My CPU is P8400... http://ark.intel.com/compare/35569

It says that VT-x is supported, but the CoreInfo tool by Microsoft said that SLAT isn't supported. :/

SLAT is only on the core i-series cpus.

from wiki:

  • Although this is not an official requirement, Windows Server 2008 R2 and a CPU with Extended Page Table (SLAT) support are recommended for workstations.[11]

http://en.wikipedia.org/wiki/Hyper_V

Nehalem and later have Second Level Address Translation (SLAT) and in general better virtualization support (2nd generation Intel VT-x) and will run Windows 8 Hyper-V just fine. The requirement as mentioned above is for decent graphics performance which isn't a concern on server which is why Server 2008/R2's Hyper-V do not have that requirement.

So if Hyper-V isn't present on my laptop, my laptop cannot run Windows 8? o_O

not correct, ur laptop will not currently have hyper v unless you are running server 2008 r2

most newer laptops nowadays should be able to run win8 which includes hyper-v

Oh I see, it doesn't even have hardware virtualization, it's not a feature of the CPU. That's what I mean, I don't have the ability to run Hyper-V.

looks like your out of luck then, sorry bud

my bad, misread the post(too much voddy)

just because you cant run hyper v has no meaning to the fact that you cant run win 8, hyper-v is just a feature.

Edited by ybrett23

installing win8 on the laptop shouldnt be a problem if win7 already works on it.

this doesnt mean hyper-v will be supported though.

as i previously stated, most laptops will run win 7 ,

and if win 8 runs as smooth as the dp then win 8 should work also, if not better than win 7

i was repying to the post "So if Hyper-V isn't present on my laptop, my laptop cannot run Windows 8?" its not a requirement to install win8.

For Hyper-V requirements, page1 has various links on what is needed.

    • That lens of history will burn if you hold it at the right angle... Warn users too late: Shame, Microsoft! That extremely minor update to an obscure Control Panel widget required 2 years of warning. Warn users too early: Shame, Microsoft! We've got better things to do. Pipeline and process be damned, we'll just always be disappointed, eh?
    • Microsoft Paint used to be my favorite Windows app as a kid, and it's still pretty good by Usama Jawad I have been using Windows since the early 2000s, when I was around 10 years old or so. I vaguely remember playing around with Windows 98 and Windows 2000, but that may have been on school PCs which had old operating systems installed. My main OS on the home PC, and the one I recall spending most time with, was Windows XP. At that time, I used the home PC to create Word and PowerPoint documents for school, but a lot of the time, I simply used it to play games. My dad would bring game discs which we would try and install on the PC, sometimes unsuccessfully, and sometimes, we would rely on flash games in the browser, like Bubble Trouble on Miniclip. However, the problem with the latter approach was the internet speed. On a good day, our dial-up internet would offer us speeds of 56 kbps, but on most days, it was closer to 33 kbps. This did not facilitate online gaming as I would often have to wait minutes for a game to load or "draw" on the screen, and trying to download pirated games wasn't simple either. I remember getting tired of waiting for online games to load and just downloading simulator games from the Big Fish Games website instead, only to be disappointed after finding out that I was just being given access to trial versions of the title, and I needed to fork out money to pay for the full version. All of this is to say that it wasn't very easy to find entertainment options on the home PC when I was a kid, due to a number of reasons, mostly outside of my control. This situation pushed me towards a rather unconventional ally: Microsoft Paint. Whenever the internet wasn't working as good as I expected, I would simply spin up Paint and draw complete rubbish on the canvas. Of course, that wasn't always the intention, but it usually happened when I messed up drawing a straight line or something, and then I would give up on that particular piece and simply draw a random collection of objects. Microsoft Paint was extremely accessible and easy to use. Even if you weren't an artist, you could quickly understand the tools at your disposal and how to leverage them on a canvas. The absolute breadth on offer ensured that each painting was truly unique, as you could utilize various combinations of tools like the pencil, paint, spray paint, and more to truly personalize your creation. Since I wasn't particularly good at drawing both on digital screen or a physical screen, I remember that my main style of art would be to insert a bunch of randomly intersecting lines and then fill them with random colors through the paint can. I have trying to replicate that art style in the latest version of Paint below, and as you can see, it's truly Pablo Picasso-esque. The human imagination truly knows no bounds Microsoft Paint kept me occupied for hours and was my best friend when video games on the home PC were inaccessible for one reason or the other. There was no academic or professional reason for which I would need to use Paint, but I still loved using it in my personal time, even if what I created wasn't worth being shown to anyone. It was simply fun. Fast-forward to today, and the situation is mostly the same. Now that I am almost 29 years old, and I still have no reason to use Microsoft Paint in a professional capacity. In fact, I don't even use it in a personal capacity, except to dabble with it from time to time, just to see if core functionalities are still intact. And I'm happy to say that I think Microsoft Paint still offers the same accessibility and inviting experience that it did to me a couple of decades ago, even though its UX has been refreshed and it's been integrated with Copilot features. Interestingly, things could have been a lot different, had Microsoft had its way. Microsoft Paint was marked for deprecation with the Windows 10 Fall Creators Update in 2017, and even began displaying a product retirement alert, urging customers to shift to Paint 3D instead. Fortunately, after consumer backlash, Microsoft reversed course on this decision, and Paint continues to be a native app inside Windows installations that can also be updated quite frequently through the Microsoft Store. Instead, Paint 3D ended up on the chopping block, which is for the better, I think. I have intermittently played around with Microsoft's refreshed Paint experience in the past few years, and I do think it has received worthwhile upgrades. the UI and the UX has been modernized while retaining core functionality, and the app is still fairly easy to use. It doesn't meet any of my use-cases, but I've never really had any use-cases ever, as described previously. Of course, the elephant in the room is the Copilot integration. Personally, I believe that this is one place where Copilot does make sense, environmental concerns aside. I know that a lot of creatives use AI to generate images, and while some may be using professional alternatives, Paint still offers a decent casual experience, with the power of Copilot. Of course, you do need to have a valid Microsoft 365 Copilot license and available credits to use it, but even if you don't, you still get the big Copilot button in the toolbar, unfortunately. All in all, I am glad that Microsoft Paint continues to be a native feature in Windows 11, and a piece of software that has evolved to meet modern needs without cutting off its own roots. It's just an iconic piece of Windows history that was an essential part of my childhood, and while I don't use it anymore, I'm just glad it is still there.

    • Hopefully this will fix the issue of no sound I have since last months stupid, and non-removable, Microsoft Corporation AudioProcessingObject Driver Update (1.0.3.56670)
    • It IS confusing! What channel are you in on each device? I'm guessing your 16GB device is on Experimental (formerly known as Dev) and your 128GB is on Beta.
