Anybody had this "can't install the update because it isn't supported by your CPU"

My original argument was against the OP being "ENTITLED" to having it work. He's not entitled to anything. Install the 8.0 CD on a supported machine and he will get his ENTITLEMENT to upgrade to 8.1.

Again you miss my point I'm entitled to upgrade(note I say "upgrade" not "work") my Win8 PC,however I agree sure my PC must meet 8.1 hardware specs,my point was I was surprised they changed hardware requirements in such a short time,also they were not clear on the hardware changes in general for the user that does upgrade from 8 to 8.1.

Did Intel pay MS money to use 64-bit opcodes that are in Intel CPUs, but not in older AMD ones? I mean, AMD invented x86-64, how can they not be compatible, unless there is some Wintel shenanigans going on.
Its actually the other way around. MS's 64bit compiler emits the 3DNow! PREFETCH/PREFETCHW instructions because there were no EM64T CPUs at the time and MS found them useful. Cedar Mill NOPs them, but Prescott users are SOL.

You've never seen it run on a 286 or 386 AT processor.

No, but I have seen Win95 on a 386SX... :p (not very useful, performance was horrible)

Also, windows actually contains a -huge- amount of legacy drivers (I think the current library is 100.000+), exactly so legacy compatibility shouldn't be a problem. Windows 8.1 still contain floppy drivers for example. I know of several IT departments that would have microsofts head, if they didn't support 10+ year old hardware. In fact you could argue that microsoft still supports the hardware, you just need to use the x86 version of 8.1. Which would likely be no great loss on such old hardware.

The other way round is more difficult, because there can be situations where you need modern hardware to run ancient OS's (thank god for virtualization). F.x. if you have some critical hardware that for some reason don't have drivers for never then f.x. Win98 or software that relies on a specific windows version which you can't upgrade because you don't have access to the source code and the manufacturer has gone out of business...

The whole point is simply, that 8.1 is more of a service pack, then a full-on upgrade of 8. I don't think its OK for microsoft to arbitrarily change system requirements with what is more-or-less a glorified service pack. If we had been talking 8 vs 9, that's another matter.

my 2c... :whiste:

Ah, so that's why. Good to know. :thumbsup:

Just saw this article over at guru3d.com:

http://www.guru3d.com/news_story/some_older_amd_cpus_do_not_support_windows_8_1.html

We contacted Microsoft for comment and received a response from a spokesperson. The statement confirms the removal of Windows 8.1 support for these AMD chips, adding: This was a change done to improve the security effectiveness of Windows by removing code that cannot use instructions such as CMPXCHG16b. Based on our data, the number of affected processors are extremely small, since this instruction has been supported for greater than 10 years.

Because I get a free upgrade to Win8.1 which I'm entitled too,I also use it for testing software and even beta software etc that I'm not sure will run on Win8/8.1 or I don't want to risk on my main PC,as I stated I do have more modern PCs.
Lets change the wording a bit -- Because I thought I would receive a free upgrade to Win8.1 which I believed that I was entitled too,

You are "entitled" to a free 8.1 upgrade. What your not "entitled" to is Windows 8.1 running on YOUR hardware. Microsoft made a decision to drop support of older AMD cpu's going from 8 to 8.1. This was a business decision. You have the right to be annoyed at Microsoft. You have the right to leave Microsoft as a customer and go to another vendor.
You are not "entitled" to Microsoft developing to your platform. You posted that you need it to test beta software on the 8.1 platform. If the 8.1 platform doesn't run on your hardware, then you have been save alot of work because the question is already answered.
You test software on the hardware it will run on. If your testing software on one PC that won't run 8.1 to see if it runs on a PC that does run 8.1 it's an invalid test anyway. You test on the same setup you'll be using in a production environment.
The real issue here is I've raised two kids, who are in their mid 20's and part of the "I'm entitled" generation and no one is "entitled" to anything. The world and it's parameters are what they are and YOU get to adapt to them, not whine till the world changes to make YOU happy.
Get a CPU that supports 8.1 and upgrade you PC and move on with it. It is what it is and it's not going to change.

I already stated that ie" entitled to a free upgrade",I don't know why you keep bringing it up all the time,as to age I'm probably a lot older then you,so as they say don't try to teach on an old dog new tricks,for the record I have already stated what I will do(clue here "LINUX") so for the record case closed.

I don't know what you are on,but my advice stay away from it ;) ,seriously do you see me moaning no,I have it sorted and moved on :) .

MODs can close this thread if they like.

Aren't they going to cut off updates to Windows 8 in 2 years unless you've gone to 8.1? I guess you'll have to find a new home for that license, hopefully it wasn't OEM.
