A friend has the following computer running Win 10 and she wants to Upgrade to Win 11

Acer ASPIRE SWITCH12 ALPHA SA5-271P-52UK 12-INCH IPS QHD(2560X1440) TOUCH 2-IN-1 LAPTOP - INTEL CORE I5-6200U 8G 256G-SSD 802.11AC STYLUS REAR+FRONT (NT.LB9SA.003-F36)

The Win 11 checker says that it cannot be upgraded due to the CPU. Everything else is OK

Can the CPU be replaced or does she need to get a new Computer?

Thanks

Simple answer, new computer

The first number on that cpu shows it’s a 6th-gen and you need at least an 8th.

Considering that's a laptop, everything will be soldered on. So it'll be a new device.

As a bit of additional context, if it was a desktop (which are generally easier to upgrade) with those specs it'd be minimum motherboard + CPU, because even though the Windows 11 compatible CPUs shared a socket with the non-compatible 6th and 7th gen CPUs, the compatible CPUs required a different chipset.

Unfortunately you cant upgrade cpu in that machine, so its a new laptop/pc unless they want to do non supported work arounds or move to Linux OS.

You can run windows 11 on sandy bridge if you wanted to. Ideally haswell for minimum security.

If they like the laptop there will be extended 1 year security patches for win10. Otherwise if you or another persons/tech is confident enough, just install windows 11 with the bypass.

It is due for a hardware upgrade though, just don’t get Intel 13/14th gen cpu if you don’t want a potential headache in a year or so.

Not sure what your background is, but googling "windows 11 upgrade on unsupported hardware" will get you plenty of results.

In fact there are even posts on Microsofts own forums (so I feel ok about posting this link):

The mobile processors don't have the same problems as the desktop processors.

vmin shift issue affected all cpus of those generational arch as it could occur at idle. The more powerful chips showed symptoms earlier. Intel hasn’t decided to disclose it fully.

As usual, I don’t have any facts to back this up, but PC prices do seem a bit higher than normal at the moment, possibly because of the Windows 10 deadline.

If so, then the “Windows 10 Extended Security Updates (ESU)” option previously mentioned is worth considering - a good choice for the lazy procrastinator. For about US$30, you can get official support for another year, and by then there might be better deals available.

Pretty sure there are a few options, bing rewards or using onedrive backup linked to the machine also gets you an extra year without having to ‘pay’

That laptop’s running a 6th gen i5, and Microsoft only supports 8th gen CPUs and newer for Windows 11. The CPU in that model is soldered to the board, so it’s not something you can replace like RAM or storage.

There are ways to force Windows 11 onto unsupported machines, but it’s not recommended since you’ll miss official support and possibly updates later. Best option is to stay on Windows 10 until it’s retired in 2025, or look at moving to a newer device.

I run a small business providing computer repairs and upgrades, and in cases like this I usually point people towards refurbished laptops — solid value and a big step up from older hardware without the cost of brand new.

Windows 10 is still supported until October 2025. Like someone else has already stated, Microsoft will offer Extended Security Updates (basically a paid subscription for extra support), but usually it works out better value to put that money into newer hardware instead.

Thanks everyone for your suggestions

I am reasonably proficient with computer upgrades etc, but by no means an expert.
If it were my computer I could manage the hacks suggested, however I am only offering advice to an elder person and don't want to spend too much time

I will tell her that she needs a new device and source a refurbished one. I have done that myself on a couple of ocassions

Again, thanks. much appreciated

Probably a wise decision if it is not your device. I see that device was discontinued in 2019.

Its quite annoying that hardware that is otherwise fine (and it will run Windows 11 just fine) is blocked soley because of that processor restriction.

I have a couple of older PCs (not officially upgradeable and much older than that laptop) that are very happily running windows 11. It actually seems to run quicker than Windows 10.

I have to wonder what MS has in mind that every windows 11 device is supposed to need that much processor power available when it doesnt seem to currently need it to run basic windows 11.

The processor restrictions are for security reasons. There are CPU bugs in older CPUs that allow unauthorised access. There are workarounds/patches in Windows to fix some of these, but not all. And some of those workarounds can cause significant performance degradation. So I believe that Microsoft is leaving those workarounds out of Windows 11, and that would make it very vulnerable on an older CPU. So blame Intel and AMD for the processor restrictions, rather than Microsoft.

This is not 100% correct. Yes older Intel CPUs suffer from spectre/meltdown exploits but both win10/11 have mitigations in the OS layer, there is a performance penalty depending on what you are doing but is negligible to basic home use.

Think database use etc. not reading emails/browsing web. The mitigations also perform better on haswell and above (4th gen).

MS are definitely not leaving those patches out, so it’s very unlikely to be the reason for the install restriction. It’s far more likely because fTPM was more widely supported beginning with 8th gen intel so they don’t have to ‘officially’ support older hardware.
