The POPCNT instruction was added to the x86 instruction set in 2008 with AMD K10 (Barcelona) and Intel (Nehalem). it returns the number of set bits in the operand: eg. the binary for 42 is 00101010, the POPCNT instruction will return 3. To perform this operation without using POPCNT can take many instructions, especially when using 64 bit operands. Microsoft decided that the performance gain was worth excluding CPUs prior to 2008.
Yes did this yesterday Brian on my old Asus 17" G750 a machine that was always great to use and too good to throw away. Now one thing I found that in the Rufus settings, I had to make it MBR and not GPT as the laptop would no accept the install because of the GPT setting. Now one thing I did was to change that 24H2 to 23H2 when I got to the Rufus settings when selecting the iso and it worked perfectly. I actually bought a key from CD Sales but found that because the drive I was using was an old 10 pro one it activated on it's install so I have a spare key👍👍 The only drawback was the old drive had a Microsoft account attached but never mind it worked and I also got the old data from the Windows.old install come across!!
@@Richretired1945 It's most likely that you have a software driver that is incompatible with Windows 11, like Core Temp program. A possible solution would be going back to your previous Windows version ==> uninstall Core Temp ==> do the Windows 11 upgrade ==> after Windows 11 update completed, you can download the latest Core Temp and installing it on your Windows 11 computer. This should resolve the Windows 11 failed update issue.
Microsoft deciding to do a hard-drop in supporting CPUs prior to 2008 (so they could use the POPCNT and string comparison instructions) isn't too bad. The problem is with their STRATOSPHERIC minimum requirements for Windows 11! They should have done something similar to all previous Windows versions: Minimum requirements that would JUST ABOUT run Windows, which in this case would be a CPU from 2008 or later that includes POPCNT and SSE4.2!
Thanks Brian. Installed on my elderly i7 920 system (circa 2008). All working well, including debloating by following your video. I seem to have a problem with waking the PC from sleep. It responds to mouse movement after sleeping but then stalls and needs a forced shut down. Have tried all the suggestions with power, cmd line to disable hibernation but to no avail. Ideas?
Last night I tried this method, but unfortunately every time I log in it says the user profile can't be loaded. It wipes the desktop settings everytime
If your CPU did not meet the min requirement, then Rufus cannot help. Is this correct?

Is it worth? your job is great. I liked the video, but I really wonder if it is worth because ultimately, MS can keep blocking future upgrades... My old system is already in LMDE and a new for me on W11...
Thank you for this information. I tried this on a Phenom II system and the installation failed with a message indicating that it requires the SSE 4.2 instruction set and evidently the Phenom II only supports 4b? I'm somewhat confused as I watched a video where Windows 11 was installed on a Bulldozer which I believe is older that the Phenom II. Am I doing something wrong?
Edit: Further to my comment below. I reverted to Windows 11 23H2 to find this version does not have the wake from sleep issue I have encountered. Not sure if this 24H2 applying other restrictions to unsupported hardware.
My work laptop is an i5 7th gen Windows 10 LTNC 21H2 i keep getting the erge to update it to Windows 11 when it still has life and it is my work support laptop should I join a Windows support groupe thank for everything you do just wish you did CCTV and network troubleshooting vids .
Just in case anybody is having problems on using older USB FD's. I keep getting error using 2 older FD, I used an older version of RUFUS and that worked. 4.0 to be exact.
This is the 2nd way to get around Microsoft's Windows 11 requirements you have posted in a week. Why other than trying to force people to buy a new computer does Microsoft keep the requirements in place. I did two old computers with the other method, and they are running fine, so the requirements for Windows 11 are obviously BS.
I have got another issue now, can you help.?? I have a dodgy USB driver and i have tried everything. I cannot run any programs from USB, the WPD filesystem volume driver is showing the exclamation triangle in device manager. I am currently backing up all my data so i can do a clean install now but if you have a fix for this WPD filesystem volume driver. Ive tried everything and a clean install is a last resort.... please help or point me to one of your tutorial videos if you have made one for this as it must be a quite a common issue...? 🙏🙏 Its gonna take me a few days if not doing this clean install.... 🙏🙏
SSE4.2 (added in 2008) includes instructions to accelerate string comparisons. Microsoft decided that the performance gain was worth excluding CPUs prior to 2008. *Additional: SSE4.2 also has the CRC32 instruction to accelerate those calculations, but ONLY for the iSCSI polynomial! Intel should have either: used 2 instructions: CRC32 (ZIP) & CRC32C (iSCSI) if using a hard-coded polynomial is faster or allowed the polynomial to be passed in a register if there is no loss in performance
@@happyputt9709 It would be so simple to just have several DLLs, each using newer groups of instrunctions and just load the one that the CPU supports. y-cruncher does that, loading the specific library optimized for your CPU.

Excellent I knew it wouldn't take long for rufus to fix it
Yeah, great bit of software
you've been able to use rufus to do this for year's m8, it works exactly the same as 23H2.
@@mcloble4229 It had a bug recently where it stopped working on 24H2 new iso
@@jasonhawkins4528 oh, thanks for the info m8 i honestly didn't know about that.
Is it possible to install Windows 11 on Windows XP or later machines? Is there a workaround for such an installation?
You most likely will need to do a clean install as I think you can only update from Win 10 to Win 11. Rufus will do the job for you .
I would personally suggest people to choose 23H2 or older build until it's eol. 24H2 is still long way to be for stable use
I agree
Thank you, Brian! 🙏🏼
I💖RUFUS! 🤠
You are so welcome
This was done by another presenter yesterday. It makes a Registry entry to make this possible.
All the code is embeded in Rufus, no need to add code to registry
@@Britec09 - YES, I thow that! I was just pointing that out.
Whatever way I try I get to the end and get a box saying Win 11 installation failed. Any help would be appreciated

Thank you! Cheers!
Thank you it works, period.
Didn't work for me. Black box opens up and closes. Nothing else shows up on screen 😕
Why bother, 24H2 is full of bugs. I rolled all mine back. I will wait a bit longer.
Use 23H2, supported until 2026
Where does one download the 23h2 ?? Yes, this is full of bugs & outlook does not sync on this !!

My system information says BIOS MODE Legacy. Is that MBR?
Yes, MBR would be legacy. To convert to GPT use mbr2gpt /convert.
@@Jon717 you can also use windows built in diskpart using command prompt to do it without using third party software.
@@mcloble4229 mbr2gpt isn't third-party software, it's built into Windows.
Is it good for LTSC ISOs?
Does this version from RUFUS bypass the lates Intel processor check as this is what's stopping one of my laptops from updating?
Yes.
@deltaechomusicnh555 thanks, I'll give it a go tonight.
If you don't mind reinstalling your programs I think the method he posted the other day is easier than this method.
@@deltaechomusicnh555no it doesn't for me, this laptop doesn't meet the sse 4 requirements and there's no bypass for that.

He did a video a couple of days ago using SuperMSConfig.
Get a specific hardware machine aka Copilot+PC and go from there.

yet doesn't support win 11
Minimum of Win 11 8gb ram

Thank you
My bios mode says Legacy
Yes rufus still better for using and can have 24h2 existing some more stuff but don't working properly rufus still the better
Crap. Followed it to the letter. Did not work at all

But not popcnt bypass
That requirement cannot be bypassed.
So on the one hand you say ‘dont install 24h2 its full of bugs’ and in another ‘how to install 24h2 etc etc’. Click bait scaremongerer.
