Is the Intel Core i7 5500U security flaw of concern if I am running Windows 10?

Yes, no, maybe?

I know that's just as clear as all the articles you've probably already read that don't seem to be able to give a clear answer, but that's the entire point. No one but a highly technical Microsoft employee with full access to all of the resources relating to both the technical and 'soft' reasons behind every single decision Microsoft has made regarding which processors would be supported with Windows 11 could possibly tell you that with any authority.

What this should tell you is that all of the articles, complaints, discussions and other noise relating to these decisions are really just so much noise, uneducated user stupidity, and don't really mean anything.

The only thing that truly matters is that Microsoft is telling you whether a particular processor is supported or not and as with my own first-generation Microsoft Surface Go tablet running Windows 10 in S Mode, if it's not supported then it's just asking for trouble trying to circumvent the protections Microsoft has put in place to keep you from putting your device and your personal information and data at risk.

There are significant differences between Windows 10 and 11 and even with possibly supported devices we've recently seen some issues with critical security and other functions with some Windows 11 updates, so purposefully attempting to bypass these checks is simply being utterly foolish and asking for potential problems.

I already pointed out that your Intel processor is clearly no longer supported by the manufacturer, so there's absolutely no support for any updates to either firmware microcode or drivers that would be (might already be) required if a new vulnerability similar to Spectre is or has been found. And since even determining whether a particular technical issue truly affects a specific processor or driver is the manufacturers responsibility, you might never even know that an unsupported processor is at risk of attack or other affects, since no one including Microsoft will be taking the time to determine this for unsupported processors or devices.

I thought what I wrote about Windows 11 above already made that clear, but now I've stated it in so many words. Only a fool would choose to run either an unsupported operating system or attempt to operate on an unsupported device. It's just asking for potential technical issues, data loss, and/or security failures for which you'd have no support from Microsoft if you tried to contact them for aid, because they already clearly told you that in so many words.

Actually, the problem with Windows 11 support for older processors is much more complex than one simple 'security flaw', which is why there have been so many articles written about it, complaints from customers with these older processors, and back-and-forth discussions along with testing and other investigations performed by Microsoft in an attempt to determine whether they truly 'got it right' when making their initial choices regarding which processors would be supported.

Here's one of the many articles from that time in July 2021 that tries to cover some of these issues and how Microsoft was responding, though it's only a snapshot, so it doesn't capture all of the potential issues and I've never seen any single article or Microsoft document that does.

Why Doesn’t Windows 11 Support My CPU?

However, regardless of any other potential reasons that your specific processor might have, there's another more critical issue that Microsoft also mentioned and most of the technical press and thus Microsoft customers chose to ignore. That's simply the manufacturer support for both the processors and in fact the devices that contain them as well.

What I mean by that are the fact that unlike with Windows 10, where Microsoft decided to take it upon themselves to support hardware going back more than 10 years in some cases, Windows 11 does actually have some relatively stringent requirements that immediately ruled out any Intel processors older than 7th-generation. And then they had to look at which of these processors the manufacturers like Intel or AMD were still officially supporting, since as with the Spectre flaws that you were discussing, Microsoft needs to be able to require that the manufacturers provide firmware-based microcode updates if a new version of either Spectre or some other similar flaws were detected that could affect Windows 11 security.

How does this issue of processor support affect you personally? Here's the Intel processor information page describing your processor and the Specifications - Supplemental Information excerpt from that page specifically related to its support.

Intel Core i75500U Processor 4M Cache up to 3.00 GHz Product Specifications

"Supplemental Information

• Marketing StatusDiscontinued
• Launch DateQ1'15
• Servicing StatusEnd of Servicing Lifetime
• End of Servicing Updates DateWednesday, June 30, 2021"

If you look closely, you'll note that not only is this processor's status 'End of Servicing Lifetime', but in fact it had actually reached End of Servicing Updates just a couple of days previous to the July 2nd, 2021 date of that other article I referenced earlier in my post.

Along with this fact, if your PC device containing this processor was produced by a major manufacturer, it's also likely that they are no longer officially supporting that computing device either, since it's nearly impossible to provide full support for a device when the processor it contains no longer has support available. All of this means that it's not possible to get firmware or driver updates for either the processor or likely the computer as a whole, which since Microsoft itself is no longer doing this for Windows 11, means the hardware is at an evolutionary dead-end.

So unlike with Windows 10, Microsoft has made the decision with Windows 11 that full manufacturer support is necessary, since to state they're providing the increased levels of security and stability that customers expect from Windows 11 would be impossible without it.

I hope this makes what's always seemed to be a muddy and confusing set of explanations that the technical press has often only made worse, at least somewhat clearer.

Just realized I wrote this from the standpoint of Windows 11, when you were asking about Windows 10.

However, what you should realize from what I wrote is that though the stringent requirements for Windows 11 don't personally affect you, they do show that the requirements for Windows 10 weren't quite as stringent, which is why these issues don't necessarily affect you.

Though it's possible that some of the security enhancements that Microsoft initially tested by adding them to Windows 10 don't function on your particular processor or device, that's not necessarily a problem, since many other individual older machines don't support these as well. The best way to think about it is that as time wore on, Microsoft eventually got the most out of the processor and other hardware in your machine and whether that was less or more capable than some other newer device really didn't matter, it's simply a fact.

Ok. This all makes sense.

I will just run with Windows 10 until it is no longer supported.

Sometime before that point, I'll upgrade the PC.

Thanks for all the time you spent answering my questions.

Hello Mark,

My name is Nada, I'm sorry that you are experiencing this issue, and I will try my best to assist you.

The security flaw that you are referring to is known as "Spectre," which affects most modern processors, including the Intel Core i7 5500U. The flaw allows malicious programs to potentially access sensitive information such as passwords or encryption keys.

While Microsoft has not released any specific information on the impact of the Spectre vulnerability on Windows 10 running on the Intel Core i7 5500U processor, it is still recommended to take precautionary measures to protect your system. This includes keeping your Windows 10 operating system and all software up to date with the latest security updates and patches.

Hope it helps you. Please let me know if you still need further assistance.

Regards,

Ok. Let me explain my ultimate purpose in asking this question.

I found instructions that will allow me to bypass the processor check and install Windows 11 on my unsupported computer.

What I really want to know is: Will I be any less safe running Windows 11 on my unsupported pc than I would be running Windows 10?

If not, then I feel like I might as well install Windows 11.

I'm not too thrilled about how Microsoft has handled this issue, but I don't expect to get very far complaining about that ;-)

Thanks,

Mark
