A clone copies the installed Windows environment and your installed apps, so you do not have to set them up again. The method works reliably only when you back up first, confirm that the new SSD fits your computer, and test the new drive before you erase or reuse the old one.
Which method keeps your installed Windows and apps
Only disk cloning copies the existing Windows installation. Microsoft’s backup and transfer features move files and settings, which is useful but different from moving the system drive. The table below separates the four options readers usually consider.

| Method | Keeps installed Windows and apps? | What it actually does |
|---|---|---|
| Disk cloning (for example Samsung Magician Data Migration or Acronis Clone Disk) | Yes. It copies the existing system drive to the new SSD. | Requires a tool that supports your target SSD. See the tool section below. |
| Windows Backup restore during setup | No. It restores backed-up content, not the installed system. | Microsoft says you sign in with the same Microsoft account used to make the backup when setting up a new PC or reinstalling Windows. Source: Microsoft Support, “Back up and restore with Windows Backup”. |
| PC-to-PC transfer | No. Microsoft’s documentation says system and OS files and applications are excluded. | Moves files and settings to another PC. It is not a substitute for cloning. Source: Microsoft Support, “Transfer your files and settings to a new Windows PC”. |
| Clean installation from Microsoft installation media | No. You get a fresh Windows install. | Previous apps, settings, or data may be removed unless you back them up first. Source: Microsoft Support, “Reinstall Windows with the installation media”. |
Before you start
- Check the drive type against your computer. Confirm the SSD’s form factor and interface (SATA or NVMe) against your computer’s documentation or the manufacturer’s support page. An M.2 connector alone does not tell you which protocol the slot supports.
- Count your internal slots. If the computer has only one usable internal slot, you will need a temporary connection for the old or new drive (covered in the steps below).
- Back up important files to a separate location. This is independent of the clone, so a failed migration does not put your documents at risk.
- Check activation and note your Windows edition. Activation rules are covered in their own section.
- Prepare recovery information if device encryption is on. Confirm with your cloning tool’s vendor how it handles an encrypted drive before you start, because the documentation reviewed for this article did not verify a complete BitLocker-specific cloning procedure.
- Resolve drive errors first. A source drive with errors can cause a failed clone or boot problems, so check the old drive’s health with the manufacturer’s diagnostic tool before cloning.
Choosing a cloning tool
Pick a tool that explicitly supports your destination SSD. Vendor tools are often limited to their own products, and the restriction is easy to miss.

Samsung Magician
Samsung describes the Data Migration feature in Samsung Magician as a way to migrate data from an existing storage device to a new Samsung SSD. Samsung states that it moves an existing OS, applications, and user data. This is Samsung’s own product description, not an independent test of speed or reliability. The software is intended for moving to a Samsung SSD; do not assume it will work with other brands. Download Magician from Samsung Semiconductor’s Magician page, and review Samsung’s internal SSD installation FAQ before you open the case.

Crucial with Acronis True Image
Crucial’s FAQ for Acronis True Image says its Clone Disk function copies an original disk to a new SSD. It requires a qualifying Crucial SSD connected by SATA, or by a SATA-to-USB adapter, when you install or launch the software. Eligibility can change, so check the current requirements on the manufacturer’s site through the Crucial Acronis FAQ before you rely on it.
Other cloning software
Acronis’s disk cloning documentation is a reasonable reference for general cloning behavior. Its disk cloning utility guide warns that a Windows clone made to an external USB hard drive might not boot, and recommends cloning to an internal SSD or HDD. Any tool you choose should be checked against its current vendor instructions.

Step-by-step: clone Windows 11 to the new SSD
- Back up your files. Copy documents, photos, and other data to a separate drive or cloud storage before starting.
- Connect the new SSD. If you have two internal slots, install the new SSD in the second slot. If you have only one, connect the new SSD with a SATA-to-USB adapter (for a SATA drive) or an NVMe enclosure (for an NVMe drive), but only if your chosen tool supports that temporary connection.
- Open the cloning tool and select the source and destination. In Samsung Magician, use the Data Migration feature. In Acronis True Image, use Clone Disk. Make the current Windows drive the source and the new SSD the destination. The destination’s existing contents will be overwritten, so confirm the target carefully.
- Let the clone finish. Do not turn off the computer or disconnect the drives during the process. Duration depends on drive size and interface, and no reliable generic time is established for every setup.
- Shut down and install the new SSD internally. Remove any adapter or enclosure, and place the new SSD in the internal slot you will boot from. Keep the old drive connected only if you want to keep it as a fallback during testing.
- Select the new drive at startup if needed. Power on and open the firmware boot menu. The key differs by manufacturer and is usually shown on the startup screen. If the new drive is not the default, set it as first in the boot order in firmware settings.
- Verify Windows. Confirm that Windows starts from the new SSD, sign in, and open several apps. Check that your files are present and that Settings > System > Storage reports the expected drive.
- Keep the old drive until the new setup is tested. Only wipe or reuse the old drive after you have used the new system for a period that satisfies you.
Activation after a drive replacement
Microsoft says substantial hardware changes, including replacing a hard drive, can cause Windows to lose activation. Before you start, open Settings > System > Activation to check the current status. Microsoft recommends linking the Windows digital license to a Microsoft account, which lets you use the Activation troubleshooter after a hardware change. See Microsoft’s guidance on reactivating Windows after a hardware change and its Activate Windows page.
A digital license or product key reactivates only if the Windows edition is the same before and after the change, so do not switch editions during the migration. Activation outcomes depend on the device and the license, so there is no guarantee that activation will be unaffected or that a new license will always be required.

If cloning fails
If the clone does not complete, or the new SSD will not boot after you have verified the connection and boot order, fall back to a clean installation. Back up your data first, because a clean install can remove previous apps, settings, and data depending on the path you choose. Microsoft’s installation media guide explains the process. Confirm activation afterward using the same steps described above.
