A PC with a Ryzen 5 3600 and RTX 1660 Ti is not automatically too old for Windows 11. Based on the documented Windows 11 requirements, the CPU, RAM, storage, firmware, TPM 2.0, graphics, and current Windows version all matter.
Windows 11 requires at minimum:
- 1 GHz or faster, 2 or more cores, supported 64-bit CPU
- 4 GB RAM or more
- 64 GB storage or more
- UEFI firmware with Secure Boot capability
- TPM 2.0 enabled
- DirectX 12 compatible graphics with WDDM 2.0 driver
- Windows 10 version 2004 or later for direct upgrade through Windows Update
The safest way to confirm eligibility is:
- Install and run PC Health Check.
- In the Windows 11 section, select Check now.
- If it says “This PC can run Windows 11”, the upgrade is supported.
- If it fails, the tool shows what is missing, commonly TPM 2.0 or Secure Boot being disabled.
If the PC is eligible, the recommended upgrade path is:
- Open Start > Settings > Update & Security > Windows Update.
- Select Check for updates.
- If Windows 11 is available, select Download and install.
Before upgrading, back up important files. The Windows 10 to Windows 11 upgrade is designed to keep files and apps in place, but a backup is still recommended before any major OS upgrade.
If Windows Update does not offer Windows 11 yet, install any pending Windows 10 updates first, restart, and check again.
