How do I replace my laptop SSD and move Windows and my games over?
Clone if the new drive is larger and the old one is healthy, or do a clean Windows install and move your files across. Either way, copy irreplaceable files elsewhere first. Shut down fully, unplug the charger, and follow your maker's service manual for reaching the drive. Never work inside a laptop while it is plugged in.

Geek With Laptop Forum, "How do I replace my laptop SSD and move Windows and my games over?", https://geekwithlaptop.com/forum/thread/how-do-i-replace-my-laptop-ssd-and-move-windows-and-my-games-over/, accessed 2026-11-10.My gaming laptop's SSD is nearly full. Windows 11, a 512 GB drive, and I have maybe 20 GB free. The laptop has a second M.2 slot, but it is hidden under the cooling shroud and I would rather replace the main drive with a bigger one so I do not have to manage two drives. I have done the RAM before, so I am not scared of the screwdriver.
What I do not know is the software side. Do I clone the old drive to the new one and swap them, or do a fresh Windows install and reinstall everything? I have about 40 games installed, a bunch of mod folders, a few launchers, and a couple of tools that took me a long time to set up. I really do not want to redo all of that. Is there a way to do it without losing stuff?
Also, will Windows complain about activation or drivers after the swap? And is there anything about the laptop being on its charger or battery that matters while I am working inside? I would like to do it this weekend.

Kenji's drag-and-drop idea will not make a bootable drive. Windows boots from hidden partitions, not only from the files you see in C:, so a file copy produces a drive that holds your files but cannot start. You need a proper clone from the drive maker's tool, or a clean install.
On compatibility, Dell's guide to upgrades says that when you replace storage in a laptop you should check the form factor, the connector (SATA or M.2) and the maximum capacity your computer supports, and that M.2 drives need compatibility on PCIe generation, physical size and keying. It also warns that if you cannot add storage alongside, upgrading means reinstalling the operating system, so back up your data first. That is Dell's page, but the same questions apply to any maker, so find your own model's page.
On the software side, Microsoft's Windows Backup guide describes how to back up your folders, settings and some apps to your Microsoft account. It will not copy game installs, so keep game libraries in the launcher's cloud or re-download them. One more check before you start: if your drive is encrypted, make sure you can sign in and find your recovery key first.

Cloning works well if the new drive is bigger and the old drive is healthy. The steps I use:
- Back up anything you cannot replace to a second drive or cloud storage first.
- Check the laptop's service manual for how to reach the drive.
- Put the new drive in a USB enclosure, clone with the drive maker's free tool, shut down.
- Swap drives, boot, check Windows starts, then run Windows Update.
I have done this on dozens of laptops. The activation is tied to the hardware, not the disk, so it normally carries across.

Fresh install, honestly. Cloning drags years of leftover junk across. For games it is mostly a download, and the saves live in the cloud or in your Documents folder. Write down the mod folders you care about and copy them separately. Your tools take twenty minutes each to reinstall if you note their settings.

One thing to check before buying: the drive in your laptop might be the short 2242 or 2280 length, and some laptops only take a PCIe drive with a certain keying. Look up your model's service manual. If it says one slot, one length, buy that length. Also look at the heat spreader, some laptops want a thin drive with no heatsink fitted.
