Want Windows 11 but not sure your PC qualifies? Microsoft added strict requirements — TPM 2.0 and specific CPUs — that block many older (but still capable) machines.
This guide lists the official requirements, shows you how to check your PC in 2 minutes, and explains your real options if it "fails" the check.

Windows 11 Official Requirements
| Requirement | Minimum |

| Processor | 1GHz+ dual-core — Intel 8th gen / Ryzen 2000 or newer |
| RAM | 4 GB |
| Storage | 64 GB |
| Firmware | UEFI + Secure Boot |
| TPM | TPM 2.0 ← the biggest blocker |

| Display | 720p, 9"+ |
Hindi: Sabse important — TPM 2.0 aur 8th-gen+ processor. 2018 ke baad ka PC mostly pass hota hai.
Check Compatibility — 3 Ways
Method 1: PC Health Check app (official)
Download Microsoft's "PC Health Check" → click "Check now" → instant yes/no with reasons.
Method 2: Check TPM manually
- Win + R →
tpm.msc→ Enter - Look for "TPM is ready for use" + Specification Version: 2.0
Method 3: Check processor generation
- Win + R →
msinfo32→ note the Processor line - Intel:
i3/i5/i7-8xxxor higher = OK (-7xxx= too old) - AMD: Ryzen 2000 series+ = OK
What Fails Most Often
- TPM 2.0 missing/disabled — most common. Good news: many PCs have it, just turned off in BIOS (look for "Intel PTT" or "AMD fTPM" and enable it)
- CPU too old — Intel 7th gen and older are hard-blocked officially
- Secure Boot off — enable in BIOS (may require switching from Legacy to UEFI)
Can You Install Anyway? (Unofficial)
Microsoft allows clean-installing Win11 on unsupported hardware with a warning — and registry/Media Creation workarounds exist:
- ⚠️ No guaranteed Windows updates
- ⚠️ Watermark/compat notices possible
- ⚠️ Do it only if you accept the risk — not for critical work PCs
- Rufus tool offers "remove requirements" during bootable USB creation
Windows 10 Support Status
Windows 10 support ended October 2025 — no more security updates for most users. Options if your PC can't officially run Win11:
- Enable TPM/Secure Boot if hardware supports it
- Unofficial install (accepting risks)
- Extended Security Updates (ESU) program
- Move to a lightweight Linux distro for old hardware
Frequently Asked Questions
What are the Windows 11 requirements for PC?
TPM 2.0, Secure Boot, 4GB RAM, 64GB storage, and Intel 8th gen / Ryzen 2000 or newer processor.
Can my old PC run Windows 11?
Check with PC Health Check app or tpm.msc. PCs from 2018+ usually pass; older machines fail on TPM/CPU — but TPM is often just disabled in BIOS.
How do I enable TPM 2.0 in BIOS?
Boot into BIOS/UEFI → find "Intel PTT", "AMD fTPM", or "TPM/Security Device" under Security or Advanced → Enable → save and restart.
What happens if I install Windows 11 on unsupported hardware?
It runs, but Microsoft warns updates aren't guaranteed and shows compatibility notices. Works fine for many — but it's unofficial.
Is 4GB RAM enough for Windows 11?
It meets the minimum, but 8GB+ is the comfortable real-world recommendation.
Windows 11 kaise check kare PC compatible hai?
tpm.msc chalao TPM ke liye, msinfo32 se processor check karo — 8th gen+ Intel ya Ryzen 2000+ hona chahiye.
Conclusion
Check first: tpm.msc for TPM 2.0 + processor generation. Many "incompatible" PCs just need TPM enabled in BIOS. Truly old hardware? Unofficial install works but weigh the update risks.
