Backing up your PC before major system changes can help prevent data loss and ensure quick recovery when system issues occur. This guide explains how to back up files and systems using MiniTool ShadowMaker before a Windows update, BIOS update, and system reset.
Why Backup PC Before Major System Changes
Major system changes can affect system stability, hardware compatibility, and overall performance. A PC backup protects your personal files, apps, and operating system if something goes wrong.
- Prevents data loss: Major system upgrades (upgrading Windows 10 to Windows 11) or Windows updates (KB installations) can sometimes crash or freeze, resulting in data loss.
- Acts as an Undo button: If a new system version or software patch causes severe compatibility issues, a full system backup can restore your computer to its working state.
- Preserves configurations: Restoring from a system crash is faster if you have a full system image. This avoids reinstalling Windows, applications, and settings.
What to Back Up Before Major System Changes
Before making a major system change, it is recommended to back up files and the system to an external hard drive or USB drive.
The following are essential items to back up:
- Personal data: Documents, photos, downloads, desktop tiles, videos, and other important data should be backed up.
- The entire system: Create a full copy of the operating system, installed apps, system configurations, and hidden partitions so you can restore Windows if an update or installation fails.
- Apps and keys: Export your browser bookmarks and backup software license keys.
When Should You Back Up Before a System Change
Always create a backup before a major system change, especially when the change could affect your files, system, or settings.
The following are common situations:
| System Change Type | Recommended Backup | Importance |
| Before starting the upgrade, such as upgrading Windows 10 to Windows 11 | System + files | Protects files and the system if the upgrade causes compatibility issues or fails. |
| Before installing Windows updates | System + files | Prevents file loss and provides a recovery point if the update causes errors, crashes, or boot issues. |
| Before resetting the PC | System + files | Protects personal files and provides a recovery option when the reset fails or removes needed data. |
| Before a BIOS/firmware update | Important files | Avoids data loss caused by a failed update. |
| Before replacing a motherboard | Important files | Prevent data loss caused by accidents during the hardware replacement process. |
