CPU not supported for Windows 10?

This is baffling because ~1/2 year ago I went through the upgrade thing to the extent that I downloaded the ISO and I burned a DVD, all using this machine. Now, I go to do the same (figure the ISO is updated now), and get a message that my CPU isn't supported for Windows 10! I doubt that's true. It supports 64bit (although I'm running 32bit Win7 right now with the machine), it's an Intel Core 2 Duo processor T5500 1.66Ghz in a Lenovo T60.

I just searched and can't find the tool I downloaded and installed/used on my other Win7 machine today that worked up a compatibility report including apps, hardware, etc.

I think that was a bogus error, but I can't prove it right now.

It may actually be your motherboard which is causing the error (at least according to Google). I believe your CPU supports CMPXCHG16B which means that it should support Windows 10. Windows 8.1 64-bit has the same requirements that 64-bit Windows 10 has so you can search for issues about that and you mind find situations mirroring what you're running into.

There are a few other instructions that the CPU must support to run the 64-bit versions of 8.1 and 10[1].

Are you running the upgrade or a fresh install? There are situations in which the upgrade won't work, but a fresh install will. This very well could be a motherboard chipset limitation on you machine, as I have upgraded two Core 2- era machines without issue.

This machine is one of two Lenovo laptops I'm thinking to move from Win7 (one's 32bit, this, the other is 64bit) to Win10 imminently. Both have "fresh" installs of Win7 on them (i.e. they were not upgrades of Vista, XP or whatever), Home Premium and Ultimate, respectively.

I am about to do a fresh install of Win7 Ultimate 64bit to the Lenovo T61 (with T7700 processor) because it's Win7 install is FUBAR, and I want to have a downgrade path in case I don't like Win10 on it. However, this machine (Lenovo T60 with the T5500 processor), the 32bit Win7 Home Premium machine's installation seems OK. I'll image it too before doing a fresh install of Win10 on it, but as I say, when I answered to the Let's Upgrade Now or whatever it's called that MS has put on this machine I just get the Can't message implicating unsupported CPU.

I created Win10 32bit install medium yesterday, it's just a microSDHC card in an adapter. I figure to backup this machine (Acronis), today and see if the Win10 install works, basically ignoring the Can't message.

The other machine,

I figure I'll just back up this machine and try the Win10 install (32 bit, because I have a few apps that won't run on 64bit, I'll do 64bit on the other Win7 laptop, I don't use it as much) and see if it works, WTH.

I'm running a core 2 duo in a 2008 era dell laptop and it's up and running on Win 10. I had a struggle with the install hanging at 99%, but finally made it over that and created an Installation USB. All good so far.

I ran into the same problem with a T510 notebook. The solution was to disconnect completely from the Internet and install Win10 from a DVD prepared by the MCT. I allowed no contact with MS until after it was installed. No problem then.

What is the "MCT"?

Yesterday I prepared a USB install device, it's just a microSDHC (8GB) in an adapter inserted in a USB device that accepts SDHC cards. I used the media creation tool to write the Win10 32bit install on it. I haven't done anything with it yet. Figure to try it, have no idea whether the install will work or not. Presumably there will be no internet connection until I establish it. I could turn off internet on the machine prior to the install just to make sure (there's a switch on the front that turns Internet on/off -- it's a Lenovo T60).

Thanks!

MCT - Media Creation Tool. So glad MS finally came out with these.

OK, cool. Well, I have my USB install device made yesterday with the MCT (guess it should work the same). I'll install from that with the Internet switch turned off, it's a hardware switch. I have a feeling it will install fine and work. In any case, I imaged my current Win7 32bit installation yesterday, so I can fall back to that if anything goes wrong... or if I'm not happy with Win10. I'm wondering if I can go back to Win10 later, say after July 29, though.

I have a DVD I burned using the ISO I downloaded more than 6 months ago, also Win10 32bit, but undoubtedly it's outdated now.

If you install and activate Win10 and then go back to 7, your 10 license should be preserved (just make sure to log in to or create a microsoft account.)

I will have to try that. Unfortunately my motherboard is old, so no update, but the CPU is a core 2 duo 8400, which should be plenty.

Prior to installing Win 10, I ran Belarc advisor and it pulled my Win7 key and found my service tag# on my Dell laptop, so I could go get a backup of all my drivers, prior to the install, just in case. After the install of Win 10, I ran Belarc advisor again and it was able to pull my Win 10 key. Might be good info to know, if one decides to reinstall Win 10 again later.

I may seem like an idiot (I wonder at times), but I have TWO microsoft accounts. It's driving me nuts, well, occasionally. One is my usual email address the other is ...@live.com. They each have their own passwords, of course.

My smartphones use the @live.com account, so I have to sign into that one to have access to my backups. I have signed into the other one a lot. I called microsoft support around a year ago, talked to folks for 2 hours, and they couldn't sort it out, why I had two accounts, what they were used for, what I could do about it, what the implications were! It was madness and I set it aside and attended to other matters.

So, when asked to sign into my MS account, I don't know which I'll use. After my install, figure I'll use my usual email address, I guess a good idea because that's the only way I'll receive email feedback from MS on anything!

Your Win 10 key is the generic key. 7 to 10 updates don't get issued a unique key.

Rather how it works is that MS takes a hash of your computer after the update. Then should you ever reinstall, it will compare hashes and activate so long as it matches the hash of an already activated system. The good news is that all of this is automatic and in the background. It doesn't require signing into any kind of Microsoft account.

Hi Virge. I have to differ with you on the Win7 key. I went back and checked the key issued when I first bought the Win7 Home 64 and what Belarc Advisor found was the exact same key I was issued at the time of purchase. Win 10, I have no idea, but should I do a clean install, after upgrading, I feel that one of those keys could be beneficial...but then again, maybe I won't need them. I hope, anyway, as I'm getting ready to do a new clean install off the USB I created earlier, when I upgraded.

I think I have two - you can't combine them, I know that much. I just use one though these days - Xbox, windows, office, visual studio (my MSDN license is tagged to it too) so its not too hard for me to figure it out.

Maybe try writing down which one you used for what?

Yeah, I have a bunch of stuff like that saved in database files. Thing is it's not just 100 words, it's a bunch of stuff to read through. It gets tiresome. If I can just change the log-in on my smartphones I might be OK just using the account that uses my actual email account. I figure there's a way to do that, change the account that the phone signs into. I'll have to devote some time to it. Right now, I'm going to focus on the Win10 installs, deal with the dual MS accounts issue later. Thanks for your input!

I'm going to try the Win10 install on this Win7 32bit machine likely Tuesday (in two days).

I did the Win10 install today in spite of the CPU not supported wall I encountered. First thing I did was switch off all connectivity using the switch on the front of the Lenovo T60 case. Installed from flash, it's activated.

Only issue I have so far (I have done virtually nothing at this time) is that one of the monitors shows only this: VIDEO MODE NOT SUPPORTED.

The laptop is attached to a minidock. Running Windows 7, I had it set up so that digital out was to a 23" monitor and VGA out to a 19" monitor. It's the VGA that says VIDEO MODE NOT SUPPORTED. I have tried a bunch of stuff including an attempt to change the resolution of that monitor, however Windows shows the res as blank, so I can't change it. Windows shows the 23" monitor as 1920 x 1080.

I searched for another driver other than the one I've had saved on my NAS for years (it's a Hyundai Imagequest L90+), but I only encounter sites that want $30, which is ridiculous. I figure there's an answer. Anyway, dual monitor is something I don't do a lot but I'd like to have it.

I'm right now installing Win10 Ultimate 64bit on another Lenovo laptop, a T61. I use that machine stand alone, so I won't have external monitor issues.
