I built my PC a few years ago without much hardware knowledge. I intended to install Windows and my games on the SSD, while using the HDD for personal files, but Windows was accidentally installed on the HDD instead. Since then, I've saved files and installed games on both drives.
I'd like to move Windows to the SSD without losing anything important, keep or migrate my games and personal files, and eventually clean up or upgrade this somewhat outdated PC. I'm looking for the safest and cheapest approach, explained step by step for a complete beginner. I'm also unsure whether deleting and reinstalling games would erase my save progress, and whether moving Windows to the SSD would require buying another license.

Deleting a game's installed files does not normally delete its save data, but it depends on the game. Cloud saves are common for games tied to an online account, while offline games may keep saves in Documents, AppData, or another user folder. Back up those folders before uninstalling anything. Game installations can usually be moved between drives through the launcher, but a fresh download is often easier and avoids broken paths after Windows is reinstalled.
You can clone the HDD to the SSD with disk-cloning software, but this only works if the used space on the HDD fits on the SSD. It also copies the clutter and existing problems, and cloning can be confusing if the drives use different partition layouts. For a beginner, a clean install is less risky and usually gives the best result.
Afterward, reinstall your programs and point game launchers to the existing library folders if they support that. Otherwise, redownloading games is often simpler. Many modern games store saves in cloud synchronization, but not all do, so look for save files in the game's documents folder or user profile before deleting anything.
If you have enough free space and a spare drive, you can reduce the amount of juggling by copying your important files there first. Do not create and delete partitions as a substitute for a backup. Encryption such as BitLocker can also prevent access if you do not have the recovery key, so save that key before changing partitions.
A practical order is: back up important files, record your Windows edition and activation status, make the installation USB, disconnect the HDD, install Windows to the SSD, reconnect the HDD, restore your files, reinstall launchers and applications, and only then erase the old Windows installation.
The safest approach is a clean Windows installation on the SSD rather than cloning the old HDD. First copy anything important—documents, photos, game saves, browser data, and anything else you cannot replace—to another drive or cloud storage. Do not rely on the two existing drives as your only backup while making changes.
After backing up, create a Windows installation USB, boot from it, and install Windows onto the SSD. During setup, be very careful to select the SSD as the installation destination. It can help to temporarily disconnect the HDD during installation so Windows cannot place boot files on the wrong drive. Once Windows starts successfully from the SSD, reconnect the HDD and copy your personal files over. You can then format the old Windows partitions on the HDD, but only after checking several times that everything important has been recovered.
Usually not. Windows activation is generally tied to the PC’s hardware, especially the motherboard, so reinstalling the same edition on the same computer normally activates automatically once you connect to the internet. You can check the current activation status before starting and make sure you install the same edition, such as Home or Pro.
Would I need to purchase Windows again after installing it on the SSD?
