To check Windows 11 CPU compatibility, find your processor’s exact model, compare it with Microsoft’s supported-processor information, then run Microsoft PC Health Check to assess the entire PC. A processor’s clock speed and core count alone do not prove that it is supported, and a supported CPU does not guarantee that the rest of the device meets Windows 11 requirements.
1. Find your exact processor model
Use Windows or your PC maker’s specifications to identify the full processor model—not just its brand, family, generation shorthand, or speed.

- Task Manager: Press
Ctrl+Shift+Esc, select Performance, then CPU. The processor name appears in the upper-right area. - System Information: Search Windows for System Information and open it. Find the Processor entry in the system summary.
- Manufacturer specifications: Look up the exact PC model on its manufacturer’s support or specifications page if Windows does not show a clear model name.
Keep the complete model string for the next step. Two CPUs in the same family can have different support status.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors2. Check Microsoft’s supported-processor information
Look up the processor family and model in Microsoft’s supported Intel processors for Windows 11 page, or the corresponding Microsoft page for your processor brand. Check the specific model rather than assuming that every CPU from a particular generation is supported.

Microsoft describes these lists as minimum supported processor models or generations. It notes that later generations following the same design principles may be considered supported even when they are not listed, and that lists may not immediately reflect new processor offerings between updates. If your model is missing or ambiguous—especially if it is a newer model—check Microsoft’s current guidance and ask your PC manufacturer rather than deciding from the generation number alone.
3. Use PC Health Check for the whole-device answer
The processor list answers a CPU-specific question. Microsoft’s PC Health Check app assesses whether a Windows 10 PC meets Windows 11 eligibility requirements and reports why it does not qualify when it fails a check. Open PC Health Check from Windows search; if it is not installed, use Microsoft’s instructions for using the app to get it. Select Check now and review the result and any stated reason.

Microsoft’s minimum processor requirement is a compatible 64-bit processor or system on a chip (SoC), running at 1 GHz or faster, with at least two cores and appearing on Microsoft’s approved-CPU list. The speed and core-count criteria are not upgradeable components: Microsoft says they are inherent to the processor as manufactured. Meeting those two numerical thresholds is not enough if the model is not supported.

If you changed hardware recently
Run PC Health Check again after changing hardware. Microsoft says eligibility information shown in Windows Update can take up to 24 hours to refresh. If the result still appears stale, follow Microsoft’s instructions for checking requirements after a hardware change, which include a manual assessment refresh procedure.
Passing a new eligibility check does not guarantee that Windows Update will immediately offer the upgrade. Microsoft says rollout timing can also depend on device eligibility, reliability metrics, age, and other factors.
