Quick TL;DR (If you just want the short version)

First try the official route: enable TPM 2.0 and Secure Boot in UEFI/BIOS and use Windows Update or the Installation Assistant.
If your hardware won’t support TPM 2.0, you can bypass the checks temporarily by either editing the installation registry (LabConfig) during setup or creating a Rufus boot USB with “Extended” options that skip TPM/Secure Boot checks. These are widely used but unsupported by Microsoft — proceed carefully.
Back up everything. Expect possible update issues, and understand Microsoft may limit updates on unsupported devices.

Why this guide exists (and why you should read it)

Are you stuck because the PC Health Check app says “no TPM” or “unsupported CPU”? That’s the common roadblock. This guide covers:

What Microsoft really requires.
How to enable TPM and Secure Boot if your firmware supports them.
How to force the upgrade safely (in-place or clean install) using Registry tweaks or Rufus.
The risks and how to reduce them.

Important safety & support warnings (read this first!)

Forcing an upgrade on unsupported hardware can leave your PC unsupported by Microsoft — security updates or feature updates may be restricted.
You must back up all personal files before trying anything — in-place upgrades can fail and clean installs erase disks.
Enabling or changing TPM/Secure Boot involves firmware settings; follow your PC/motherboard maker’s instructions. If unsure, consult support or a tech-savvy friend.

What you need (prep checklist)

A full backup (external drive or cloud) of documents, photos, and any licenses.
Your Windows product key (if you have one).
A USB drive (≥8–16 GB) for installation media.
Windows 11 ISO (downloadable from Microsoft) or the Windows 11 Installation Assistant.
Patience — some installs take time and multiple reboots.

Understanding Microsoft’s Windows 11 requirements (short)

Windows 11 expects modern security features like TPM 2.0 and UEFI Secure Boot, plus minimum CPU, RAM, and storage thresholds. These aren’t just bureaucracy — they’re there for hardware-level security. If your PC meets those, use the official upgrade flow.

Two upgrade strategies — which should you pick?

Official (recommended when possible): Enable TPM & Secure Boot, then upgrade via Windows Update or Installation Assistant. Safer, supported.
Force / Bypass (unsupported): Use the LabConfig registry method during setup, or create a customized boot USB (Rufus) to skip checks. Works for many older PCs — but be ready for possible issues.

Method A — Official route: enable TPM & Secure Boot and upgrade

Step 1 — Check your current TPM / Secure Boot status

Press Windows + R, type tpm.msc, Enter. If you see TPM management and version 2.0, you’re good.
For Secure Boot, open Settings → System → About → Advanced system info → Click UEFI/BIOS or check firmware options. (Different OEMs show this differently.)

Step 2 — Enable TPM & Secure Boot in UEFI/BIOS

Restart and press the firmware key (Delete, F2, F10, Esc — depends on your PC).
Find Security or Trusted Computing section → enable TPM (may be called PTT on Intel, fTPM on AMD) and Save & Exit.
Enable Secure Boot under Boot settings if it’s off.
Reboot to Windows. Microsoft documents how to enable TPM in many PCs — check their guidance for specifics.

Step 3 — Upgrade using Windows Update or Installation Assistant

Settings → Windows Update — if eligible, you’ll see Windows 11 offered.
Or download the Windows 11 Installation Assistant from Microsoft and run it to perform an in-place upgrade.

Method B — Use the Windows 11 Installation Assistant (official, friendly)

Download from Microsoft’s Windows 11 download page.
Run the Assistant — it checks compatibility and walks you through the upgrade.
Choose to keep files/apps or perform a clean install. (Keep files if you want minimum hassle.)

If the Assistant refuses due to hardware checks, move to Method C or D below.

Method C — Force upgrade by editing the install Registry (LabConfig)

This is the classic “install anyway” trick used while booted into the Windows 11 installer. It skips the TPM / Secure Boot checks during setup.

What it does (in plain English)

During setup you open the installer’s Registry Editor and create a key called LabConfig that tells Setup to ignore TPM, Secure Boot, or CPU checks. Microsoft documents similar approaches as workarounds in community answers; it’s widely used but unsupported.

Step-by-step (clean install or in-place from setup.iso)

Boot from your Windows 11 USB or mount the Windows 11 ISO and run setup.exe if upgrading inside Windows.
When you see the “This PC can’t run Windows 11” message, press Shift + F10 to open Command Prompt.
Type regedit and press Enter to open Registry Editor.
Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\Setup
Right-click Setup → New → Key → name it LabConfig.
Inside LabConfig, create DWORD (32-bit) values with value 1 for the checks you want to bypass, for example:
- BypassTPMCheck = 1
- BypassSecureBootCheck = 1
- BypassCPUCheck = 1
Close Regedit and the Command Prompt, then continue Setup. Setup should proceed.
Finish installation and install drivers.

Notes & caveats: This lets you install Windows 11 but may limit future updates and Microsoft may display warnings. Back up first.

Method D — Use Rufus to create a “bypass” Windows 11 USB

Rufus (a popular third-party USB tool) can build a Windows 11 installer that disables setup checks during installation — the “Extended Windows 11 Installation” option. This is simpler than the Registry hack for many users. Tom’s Hardware and other guides document this approach.

Step-by-step using Rufus

Download the latest Rufus from its official site.
Download the Windows 11 ISO from Microsoft (choose Release channel).
Run Rufus, choose your USB drive, and select the downloaded ISO.
In Image option, pick Extended Windows 11 installation (or the dialog that lets you disable TPM/Secure Boot checks).
- If you don’t see it immediately: click START — Rufus shows a customization dialog where you can uncheck TPM/Secure Boot checks and the Microsoft account requirement.
Click Start and wait. Rufus will create a USB that bypasses the hardware checks.
Boot from that USB and install Windows 11 (clean install or upgrade option depending on your needs).

Important: Rufus evolves; menu labels and steps change across versions. If you can’t find the exact option, check the Rufus changelog or help pages.

Method E — Clean install from modified ISO (advanced)

If you prefer manual control, you can extract the ISO, replace certain setup files, or use a combination of the LabConfig registry tweak and a normal bootable USB. This is more advanced and only recommended for experienced users.

After the upgrade — what to do first

Install chipset & GPU drivers from your PC/motherboard vendor.
Run Windows Update several times until it’s clean.
Reinstall apps and restore documents from backup.
If you used a bypass, don’t assume future feature updates will be seamless — keep a recovery drive handy. Windows Central

Troubleshooting common problems

Setup still blocks you: Double-check the precise bypass you used (LabConfig keys or Rufus options); try creating fresh install media.
Blue screen or driver errors after install: Boot into safe mode and update drivers.
Windows Update fails after install: Unsupported devices sometimes get partial updates — consider staying on a stable Windows 10 until you can upgrade hardware.

Risks, support, and Microsoft policy (short)

Microsoft is clear that TPM 2.0 and Secure Boot are core Windows 11 requirements; bypassing them makes your install unsupported and may limit cumulative/security updates or future feature upgrades. That’s why enabling TPM in firmware (if available) is the best route.

Best practices & final tips

If possible, enable TPM and Secure Boot in firmware — it’s the safest, supported path.
Keep a Windows 10 recovery USB ready in case you need to roll back.
If you rely on your PC for work, wait for hardware you can support or test the upgrade on a spare drive first.
Document the exact changes you made (Registry keys, Rufus options) so you can reverse them.

Conclusion

Forcing an upgrade to Windows 11 is doable: your safest bet is enabling TPM & Secure Boot if your hardware supports it, then using Microsoft’s Installation Assistant. If hardware blocks remain, the LabConfig registry trick and Rufus extended installer are popular ways to bypass the checks — but remember they’re unsupported and carry risks (updates, security, possible instability). Back everything up, read the steps carefully, and pick the method you’re comfortable with. If in doubt, test on a spare machine or consult a pro.

Frequently Asked Questions (5 unique FAQs)

Q1 — Will my Windows 11 stay activated if I force an upgrade?
A: Usually yes if you had a genuine Windows 10/7 key or digital license tied to hardware, but activation can be unpredictable on unsupported installs. Keep your product key and account info handy.

Q2 — Will Microsoft block security updates on a PC that used a bypass?
A: Microsoft can limit or mark updates for unsupported devices. You may still receive some updates, but feature updates or full support is not guaranteed.

Q3 — Is Rufus safe to use for this purpose?
A: Rufus is widely used and reputable, but always download from the official Rufus site and follow instructions. The tool only creates installation media — the risk comes from skipping hardware protections.

Q4 — Can I re-enable TPM / Secure Boot after installing Windows 11 with a bypass?
A: Yes, in many cases you can enable TPM/Secure Boot later in firmware and Windows will use it normally. However, results vary depending on hardware and how you installed Windows.

Q5 — What’s the safest option if I want Windows 11 but my PC is old?
A: Either enable TPM if your motherboard supports it, or plan a hardware upgrade. For mission-critical systems, avoid bypassing and consider upgrading hardware to meet Microsoft’s requirements.
