The Dell brand alone cannot determine compatibility; run Microsoft’s PC Health Check app on the desktop for a definitive Windows 11 eligibility result.
Check automatically
- On the Windows 10 taskbar, select Search.
- Type PC Health Check and open the app.
- If it is not installed, download it from Microsoft’s PC Health Check download.
- In the Introducing Windows 11 section, select Check now.
- Review the result:
- This PC meets Windows 11 requirements — the computer is eligible.
- This PC doesn’t currently meet Windows 11 system requirements — expand the results to see which component failed and whether anything can be changed. ^1^
You can also select Start → Settings → Update & Security → Windows Update → Check for updates. Windows Update reports whether the computer is eligible and may offer Windows 11 when it is ready for that device. ^2^
Requirements you can check manually
The desktop must have at least:
- A Microsoft-approved processor running at 1 GHz or faster, with at least two cores
- 4 GB RAM
- A 64 GB or larger storage device
- UEFI firmware with Secure Boot capability
- TPM 2.0
- DirectX 12-compatible graphics with a WDDM 2.0 driver
- A 720p display larger than 9 inches
- Windows 10 version 2004 or later for upgrading through Windows Update ^3^
The processor, TPM 2.0, and UEFI/Secure Boot requirements commonly determine whether an older desktop qualifies. More RAM or storage can sometimes be installed, but an unsupported processor is generally not an easy upgrade.
If PC Health Check says the computer is eligible but Windows Update does not yet offer Windows 11, a compatibility safeguard may be temporarily delaying the upgrade because of a known driver or application issue. Wait until Windows Update indicates that Windows 11 is ready rather than bypassing that safeguard. ^1^
Windows 10 support ended on October 14, 2025, so an ineligible computer should be replaced with a Windows 11-compatible device or handled through an applicable extended-support option rather than left indefinitely without security updates. ^1^
