Upgrading to Windows 11 should not erase your data if you follow the recommended upgrade process. However, it is always a good idea to back up your important files and data before proceeding with any operating system upgrade, just in case something goes wrong during the process.
Microsoft has provided an upgrade assistant tool to help users upgrade their Windows 10 systems to Windows 11. This tool is designed to preserve your existing files, programs, and settings during the upgrade process. The tool will also perform compatibility checks to ensure that your system meets the minimum requirements for Windows 11.
It is important to note that if you perform a clean install of Windows 11, you will lose all of your data unless you have backed it up elsewhere. A clean install involves erasing your current operating system and installing Windows 11 from scratch. This option is typically used when upgrading from a much older version of Windows or when the existing operating system has become too corrupted to function properly.
In summary, upgrading to Windows 11 using the recommended upgrade process should not erase your data. However, it is always a good idea to back up your important files and data before proceeding with any operating system upgrade, just in case. If you are unsure about the upgrade process, it is recommended to seek assistance from a qualified technician or Microsoft support.
