Installing older OS on newer PCs

I need to run some 32 bit legacy software and some old hardware (Scanner) that will not work with Win10.

Can Windows 7 32bit and XP be installed on newer PCs ?
If Yes ... How new ?     ....... How about an Intel i3 ?

I know that anything above 4gig memory is wasted on 32 bit systems.

(These PCs will not be connected to the internet or my LAN so security will not be an issue).

Windows 7/XP can be installed on newer hardware with no issues. Correct, 32bit can see above 4Gb ram, but will only utilize 3 Gb.

Question I have is why dont you just create a VM if you have the means. That way, hardware wont be an issue.

My other concern is that you may not be able to activate the Windows XP install. You will be able to activate 7.

Drop it onto a VM. Use oracle virtualbox or VMware Workstation.

That's your best and easiest option.
You can actually install VirtualBox on Windows 10 and run 7/XP as a virtual machine. I still believe VB is free.

Yes it is
Lee W, MVPTechnology and Business Process AdvisorCommented:
Windows 7 CANNOT be installed on newer PCs because Microsoft doesn't support newer PCs.  7th gen intel CPUs and Ryzen AMD CPUs will block things and good luck finding drivers... especially for things like USB.  XP will be even worse.

That said, there's always a POSSIBILITY you can make an older newer PC work (especially if you're keeping it off the internet and security updates are not generally a problem)... but the newer they get the more difficult it will likely be if it's possible at all.

Easy fix - get a new scanner!

Windows 10 Pro machines use Hyper-V -- better to use a Type 1 Hypervisor than a Type 2 Hypervisor

And you can also try Windows 10 32 bit.

Most new computers will not allow you to install old operating systems like Windows 7. Vendors set up their hardware to prevent this.

If Windows 10 32-bit won't work for you, then you must run Windows 7 as a Virtual Machine. I use VMware Workstation, but other products including Hyper-V work as well.

>>  Can Windows 7 32bit and XP be installed on newer PCs ?

Only if there is chipset support for the OS.  Modern Intel CPUs don't support older OSes.  Even Windows 7 is no longer supported for very modern CPUs.  Check the Intel site and see if there are drivers for the CPUs you wish to use.

For XP support get Windows 7 Professional and use XP mode

Scanner support, try VueScan  Browse their supported scanners and see if yours is there.

Also do not forget, SMBv1 is now gone. Old scanners need SMBv1 and so in more need for Windows 7 unsecured to use SMBv1

John: it is not vendors but Microsoft that set the policy. 
Announced April 2017
This is a windows update policy, drivers are another issue

Er ... I don't believe so.  Only if they were networked would this apply.

I can get a old HP PCs with i3 processors running Win7 64bit for under €100  (Probably older than 10 years)

Would these take 32bit Win7 & XP ?
JohnBusiness Consultant (Owner)Commented:
Yes you can do that. No issue.   Also Windows 7 32-bit if you wish to reformat and do that.
dbruntonQuid, Me Anxius Sum?  Illegitimi non carborundum.Commented:
If they are running 64 bit Windows 7 they should be able to run 32 bit Windows 7.

Check with HP support web site and see if they have drivers for the machine (both Windows 7 and XP).  You should be able to find the proper link using the model number of the HP.

I presume that virtual machines will solve the hardware incompatibility problem.  Is that not correct?  The Author would benefit by knowing it seems.
Lee W, MVPTechnology and Business Process AdvisorCommented:
You don't have to go that old.  6th gen or older is usually fine.  5th gen is almost certainly fine (there were a few 6th gen that had issues).  The CPU generation is in the model number...

Intel i3/i5/i7 3-digit are first gen.
2xxx are second gen
3xxx are third gen

VMs MAY work but USB has been historically tricky with certain virtualization platforms.  if this scanner is USB, it may not work running the PC in a VM.
Philip ElderTechnical Architect - HA/Compute/StorageCommented:
Has there been an attempt to install the software onto a Windows 10 machine?

32-bit software can be installed on a Windows 7/8/8.1/10 64-bit (AMD64) hardware and OS.

Does the scanner connect to the machine via USB?

If yes, then set up Hyper-V on the Windows 10 machine, purchase a license for Fabulatech's USB over Ethernet, pass the scanner through to a Windows 7 VM, and work with it that way.

I suspect that the setup may work when plugged natively into Windows 10. We have an Epson photo printer that wouldn't work with early versions of Windows 10 but now works just fine with 1803 and later.
Virtual Box will run 32bit Windows XP, and it's free. The problem is getting the usb/serial interface of the scanner attached to the virtual machine so the software can recognize it and run. It would be better to find modern scanner drivers than to have to boot up a virtual machine, but since modern computers don't even have parallel or serial ports, it may be tricky to get it connected.
Also all virus scanning software has dropped support for Windows XP, so you have to be careful how you transfer files from the XP machine to the location you want. Virtual Box makes it easy to clone your setup, so in case of infection, you can delete and re-clone a working setup.
