Intel Processor: Intel(R) Core(TM) i7-5820 CPU @ 3.30GHz for Windows 11



I have this processor in my PC:  Intel(R) Core(TM) i7-5820 CPU @ 3.30GHz

When I run Microsoft's application to see if my PC can be upgraded to Windows 11 the following message appears in the results:



 When I look up the minimum CPU requirements for Windows 11 

  • Processors/CPUs (Central Processing Units): 1 Ghz or faster with 2 or more cores and appearing on our list of approved CPUs. The processor in your PC will be a main determining factor for running Windows 11. The clock speed (the 1 Ghz or faster requirement) and number of cores (2 or more) are inherent to the processor design as it was manufactured and are not considered upgradable components.

My CPU is 3 times faster than the minimum requirement and it has 6 cores.

Why doesn't (and will it ever) my processor  appear in the list of approved CPUs for Windows 11?

Thank you,

Microsoft has decided to support only 8th gen processors and above, with a few 7th gen processors allowed (for their laptops).

You have not looked at the list of supported processors:


And, while you think your processor qualifies, there are other requirements, like PTT/TPM and Virtualization-Based Security (VBS). 


Now, you can still run Windows 11, but at your own risk.   Personally, I see nothing needed in Windows 11.  And, Windows 10 is supported until 2025.  But, if you insist, have at it.


Do not complain if you have problems, or Microsoft decides to pull the rug out from under you.

Hello AlHill,

Thank you for your response.  I did look at the list of processors and mine is not in it, so I'm missing why I should look there.  Apparently, in any case, I cannot upgrade to Windows 11 on my PC.  I am sad, because I selected all 'top of the line' components and paid quite a lot to purchase my Alienware Area 51 PC.  I won't be buying another anytime soon. Not pleased that it already cannot meet minimum requirements for the next Windows upgrade.

You should complain to Microsoft.  It is their list and they decided what to support.

Your system is 7 generations into the past. 7 Generations = 7 Years. Anyone expecting full support for this long is only fooling themselves; you simply aren't going to get it. Your warranty is long over (it was likely 3 years or perhaps less). 

Just saying,
