"I recently purchased a new SSD to replace my old, smaller one, and I'd like to install Windows 10 on it. I suppose I could dd the Windows partition to the new drive, but I intend to start from scratch. Will it work if I simply unplug the old drive, insert the new one, and install Windows from a bootable USB stick before entering the product key I used to activate my previous installation? If not, how can I accomplish this?"

Are you also afraid of losing your Windows License Key when upgrading to a new SSD? Actually, in Windows 10 and Windows 11 OS, you are allowed to upgrade to a new drive and reinstall Windows while keeping the same Windows license as long as you don't change the computer and motherboard. When you replace the new SSD and restart your computer, it will automatically recognize the same license and run Windows with it.

Windows License is a legal agreement between you and Microsoft that allows you to use their Windows operating system on your computer, which is tied to the motherboard. So, you don't need to worry about losing it while reinstalling Windows on a new SSD. However, there are some requirements you must satisfy before reinstalling Windows:

  • *️⃣Do not change your computer's motherboard or CPU.
  • *️⃣While reinstalling Windows, ensure the old disk is not plugged in.
Suppose you don't want to reinstall Windows or lose any data saved on your old HDD/SSD while upgrading SSD. In that case, there is another way out: cloning the old disk to the new disk, which will create a 1-to-1 copy of your original disk, including the operating system, installed applications, personal files, system-related settings, configurations, music, videos, images, etc. 

The post will also cover the clone method to help you upgrade your SSD with a professional disk cloning tool - EaseUS Disk Copy. You can use it to migrate Windows 10 OS to a new disk while keeping all your data intact.
