Cloning an exact copy of your hard disk is a good move and is a good (fast) method in restoring the Windows OS when things get messed up. Keep in mind, when you clone a disk, it is the exact copy of the disk on the date that you made the copy and is a good idea to do this on a regular basis. I typically update and keep available a cloned copy of my hard disk at least once a year. My routine file backups I do on a more aggressive schedule. Cloning is also an excellent option when you want to move your current Windows 10 OS to a new drive that you have decided to upgrade and install.
Make Tech Easier will walk through the cloning process using the FREE software options of EaseUS or AOMEI Backupper (see source link below). Both of these software options are excellent choices.
So you bought an SSD drive, and you want to move your Windows 10 OS to the new drive. Here are a few ways you can clone and swap the OS install to an SSD.
