Start with the right checks.
Age alone does not settle the question. Processor support, security hardware and other requirements matter. Establish the exact computer model and the result from Microsoft’s eligibility tool before deciding whether an upgrade is practical.
What to do next.
Record the PC manufacturer and model. If someone manages the device for work, ask them to check the upgrade route.
Get PC Health Check through Microsoft’s official guidance. Run the eligibility check and read the explanation for each unmet requirement.
Save the result without including personal account details. Separate an eligible PC awaiting an upgrade from a PC that fails the requirements.
Review important applications, printers and other equipment with their providers before booking an upgrade. Eligibility is the starting point, not a complete compatibility test.
Check the result.
You should have a clear result and a list of anything still needing review. Avoid treating a large amount of memory or a new drive as proof that the processor or security requirements are met.
Stop and get help if…
The proposed solution involves bypassing installation checks or changing unfamiliar firmware settings. Get a supported recommendation first. Replacing hardware without understanding the failed requirement can waste money and interrupt access.
