Can your PC run Windows 11? Check before buying parts
Quick answer
On a Windows 10 PC, start with Microsoft PC Health Check and record every failed requirement. More RAM or an SSD cannot resolve an unsupported CPU. A missing TPM message does not yet establish that you need to buy a separate module.
Find the exact parts in your PC →A Windows 11 eligibility failure does not tell you what to buy. Find the reason on the working PC first, then decide whether any hardware needs replacing. Start with the read-only checks below and use the result to plan your next step.

Get the Microsoft eligibility result
Open the Microsoft PC Health Check instructions linked below. If the app is missing, use the installation link on that page. In the Windows 11 section of the app, select Check now and record every failed requirement.
Passing does not guarantee an immediate upgrade offer: Microsoft may temporarily hold an upgrade for app or driver compatibility. PC Health Check also does not check the graphics card or display; their requirements are listed separately on the specifications page.
| Result | What to establish before buying |
|---|---|
| Processor not supported | Record the full CPU model and investigate the current board’s upgrade options. Extra RAM cannot fix this failure.Go to this check → |
| TPM missing or below version 2.0 | Read the status and Specification Version. A missing TPM needs investigation in the device documentation.Go to this check → |
| UEFI or Secure Boot issue | Record the boot mode and Secure Boot state in Windows. Do not change the boot mode by trial and error.Go to this check → |
| RAM or storage shortfall | Distinguish OS minimums, drive capacity and free space, then check whether a proposed replacement fits.Go to this check → |
| Eligibility check passes | Check apps, drivers and your backup. The eligibility result alone gives no reason to buy replacement parts.Go to this check → |
If the processor is not supported
Record the complete CPU name in Settings → System → About. “Core i7” or “Ryzen 5” without a model number is not enough to select a replacement. Clock speed and core count alone do not establish Windows 11 support: Microsoft requires a compatible processor.
First investigate whether the exact motherboard supports a suitable CPU and which BIOS it needs. If there is no suitable upgrade on that platform, compare the complete cost of a CPU, board, compatible memory and cooler mounting. For a laptop or branded prebuilt, check upgradeability in the complete system’s service manual. Save both plans before ordering parts.
Read the TPM 2.0 status
Press Win + R, enter tpm.msc and open TPM management. Read the status and Specification Version. Windows 11 requires 2.0; Manufacturer Version is a different field.
If no compatible TPM is found, it may be disabled. Check the exact model’s manual: firmware TPM may be named Intel PTT or AMD fTPM. Do not buy a random module based on its pin count. Reading the status is enough for this check; do not clear the TPM or reset settings. Use manufacturer instructions for any later change, with a backup and the encrypted drive’s recovery key ready.
Check UEFI and Secure Boot without changing BIOS
Press Win + R and enter msinfo32. In System Information, read BIOS Mode and Secure Boot State. UEFI with On means Secure Boot is enabled. Off and Unsupported are different states; record both fields before consulting the manual.
Windows 11 requires UEFI firmware with Secure Boot capability. A disabled feature does not establish that the capability is absent. If the mode is Legacy, do not simply switch it to UEFI or disable CSM to obtain a passing result: an unprepared Windows installation may stop booting. The migration procedure depends on the PC and its current disk. Before changes, obtain manufacturer instructions, a data backup and an accessible recovery key if encryption is enabled.
RAM and storage: OS minimums versus a useful upgrade
The Windows 11 specifications list at least 4 GB RAM and a storage device of 64 GB or more. Device capacity and available free space are different figures; updates also need space. These minimums do not define a comfortable configuration for your games or work applications.
A memory purchase needs the supported DDR generation, available slots and board capacity limits; Windows 11 does not mandate DDR5. Plan data migration or OS installation separately before replacing the system drive. A larger SSD does not change a CPU, TPM or firmware failure. Standard Windows 11 and Copilot+ PC requirements differ: do not buy an NPU solely for basic OS eligibility.
Make a plan before upgrading
Separate documentation questions from actual purchases. For example, if the CPU passes and only TPM is missing, investigate firmware capability first. If both the CPU and RAM fail, buying memory alone leaves the CPU issue unresolved.
RigVela can compare parts when you plan a replacement, but does not assess Windows 11 eligibility, TPM state, installed firmware or drivers on your PC. Run the Microsoft check again on the working computer after planned changes. Before installing the OS, separately check your essential apps, devices and backup.
Quick checklist
- Record every failed requirement and the full CPU and board models.
- Check TPM and boot questions in the exact device’s documentation.
- Tie each purchase to a specific failure and include related parts in its cost.
- Back up data and locate the recovery key if the drive is encrypted.
- Check Microsoft eligibility and essential apps separately from part compatibility.
Common questions
Does “TPM not found” mean I need a module?
That has not been established. Read the tpm.msc result and check the exact model’s documentation for firmware TPM support. An unknown state does not prove the feature is absent.
Read the TPM status →Does Secure Boot being off mean my PC is incompatible?
Not necessarily: the requirement concerns Secure Boot capability with UEFI. Record the BIOS mode and feature state, then consult the manufacturer. Changing the boot mode without preparation can prevent Windows from starting.
Read the boot mode →Will a new SSD or more RAM make the PC eligible?
Only if the purchase addresses the relevant shortfall. It cannot resolve a CPU, TPM or firmware failure. Start with all the reasons reported by Microsoft and price the complete solution.
Separate memory and storage needs →Does a compatible RigVela build guarantee Windows 11 eligibility?
No. Part compatibility does not read TPM state, UEFI mode or installed BIOS and is not a Microsoft eligibility check. Use PC Health Check and manufacturer documentation for the working PC.
Plan the remaining checks →Compare the parts for your planned upgrade
Once you understand the Microsoft failure, compare the replacement parts you are considering. RigVela does not assess Windows 11 eligibility, TPM state, boot mode or the BIOS installed on your PC.
