Cloning a hard drive - Windows

My home PC is dying, want to clone the C drive,  from Lifehacker

What You'll Need

There are a number of different ways to go about this, but we've found this to be the easiest and most reliable method. Here's what you'll need:

• Your current hard drive, with Windows installed. For simplicity's sake we'll call this drive—that is, the drive you're migrating from—your "current hard drive" throughout the tutorial.
• A solid-state drive. This is the drive you'll be migrating to. To get a rough idea of how big it should be, head to your current drive, navigate to C:\Users\ and right-click on your user folder. Hit Properties, and mark down how much space that folder takes up. Head to My Computer and note how much space Drive C: has filled up, and subtract your user folder's size from C:'s total. That's how big your SSD needs to be, though I'd give yourself a good deal of wiggle room for future updates and new programs. We'll assume, for the purposes of this guide, that you've already installed your new hard drive and are ready to migrate your data.
• A backup of all your data. Since you can't clone only part of a drive, you'll need to remove your music, movies, and other personal files from your current drive before migrating Windows to the SSD. That means you'll want to back up your data somewhere else—whether that be an external drive, a spare internal drive, or the cloud. Just make sure that data is safe and recoverable, since we'll be restoring it later on.
• EaseUS Todo Backup Free. This is the program we'll be using to migrate your installation. It's easy to use, free, and it can clone partitions from a big drive to a smaller drive, which is crucial for this process (since your SSD is probably smaller than your current hard drive).
