Old School To New
Old School To New
Not as close to me as I think. The machine I’m using right now has a Windows XP boot disk (hard drive), a Windows 7 boot disk (SSD) and two Windows 10 boot disks (SSDs). It’s on its second motherboard and either the third or fourth CPU.
I haven’t upgraded my regular PCs to Windows 11 yet, but I did install it as a virtual machine in Hyper-V when it was first released several years ago. Most of my older systems don’t meet the full requirements for Windows 11—especially regarding modern CPUs, Secure Boot and TPM v2. I’ll decide how to handle Windows 10 in October 2025.
People have mentioned that the best way to install Windows 10 or 11 is to download an ISO image of the correct OS and burn it onto a USB drive (I use a tool called Rufus for this).
After that, you remove all drives except the one you’re installing, change the BIOS settings to boot from USB, and let the setup install the new operating system. Once done, unplug the USB, switch the BIOS back to boot from the new drive, and reconnect your other drives.
As @titan points out, if the original activation key and license came from a Windows 7 build, you might need to reverse-engineer the Windows 11 installation to keep your license valid. This involves downloading a Windows 10 ISO and creating a bootable USB stick for it. You’d start the new machine from this USB, install Windows 10 on the SSD, enter your existing 25-character key during setup (if prompted). After completion, plug out the USB, boot into Windows 10, connect to the internet, and hope Microsoft recognizes your build and applies the activation.
You can then attempt an in-place upgrade to Windows 11 either inside Windows or after booting from a Windows 11 USB drive. I’m not entirely sure about these final steps since I haven’t done a 10 to 11 upgrade this way—just a few tries with 7 to 10.
Thanks for the heads up ...
My install states "Windows is activated with a digital license linked to your Microsoft account" ...
My account is good along with Microsoft 365 (Office) ....
It is my understanding with the keys linked to my account ... the hardware does not matter.
It applies if you possess a 'Retail License', meaning you acquired the appropriate license from an authorized vendor when setting up your initial computer. This could very likely be a Windows 7 Home Retail License. If you purchased the first machine from companies such as Dell, HP, Lenovo, etc., the license would remain non-transferable and 'OEM', meaning it's exclusively linked to the original hardware. A 25-character product key is required to enable Windows installation during setup, though this is distinct from actually activating the license. These two steps are separate actions. You may install Windows using a generic key and keep it inactive, but you'll miss out on certain features. A generic key can also be used if you temporarily lost your retail key; upon retrieving it, you can swap the generic key for the retail one, connect to the internet, and hopefully reactivate your operating system. Only Microsoft's terms allow running a single retail license per computer. After activating a retail license on a new machine, you should not reuse the same retail license on the old device. You may de-register your previous machine online before installing it again, which will disable activation on the old system but keep it operational with reduced capabilities. The situation remains quite complex and the guidelines frequently shift. I've tried to clarify the present circumstances, though even Microsoft representatives sometimes provide inaccurate details. Regarding Microsoft Accounts, I don't associate any Windows version with my account, opting instead for traditional local accounts where I can select a primary user name rather than a random character string from Microsoft. This process is becoming increasingly complicated with the latest Windows 11 updates.
