Windows 10 standard support ended on October 14, 2025. Older Windows versions are also outside normal support. Extended Security Updates may be available for eligible Windows 10 installations, but enrollment and terms must be checked directly with Microsoft. Do not assume an unsupported system is receiving normal security fixes.
Check compatibility before upgrading
Use Microsoft’s current Windows 11 compatibility guidance and PC Health Check to verify the processor, TPM, Secure Boot, memory and storage requirements. Confirm application, printer and other peripheral compatibility. Do not bypass hardware checks as a routine upgrade strategy.
Protect files and plan the move
Make a verified backup, retain encryption recovery keys and software licenses, and allow time to test required applications. On a business network, coordinate the migration with the administrator. Update Windows 11 after installation and verify files, security settings, backups and peripherals.
If the computer is not eligible
Compare supported replacement hardware with any applicable temporary extended-update option. Budget for data transfer, application installation and user setup. An operating-system upgrade does not guarantee better speed or prevent every security incident.
