Windows 11 Updates After a Bypass Install Why Feature Updates Fail and How to Fix
Your bypassed Windows 11 takes its monthly updates quietly — then a big version upgrade arrives and fails with the same hardware message as before. Nothing is broken. Here is why the two update types behave differently, and how to get the big one installed.

🎥 The original bypass install is in the video — this page covers the upgrade you will face every year or so
There are two kinds of Windows 11 updates, and a bypass install treats them very differently. Monthly cumulative and security updates do not re-check your hardware — they download and install normally, which is why your PC has felt completely ordinary. Feature updates — the yearly version upgrades — are effectively a fresh Windows installation laid over the old one, and their setup program runs the compatibility check again. On unsupported hardware, that check fails, and the upgrade stops or rolls back.
👆 Microsoft's own upgrade key — the documented way to let Setup upgrade a PC whose TPM or CPU is unsupported (command shown exactly as it is run)
1
First, Confirm Which Update Is Failing
Open Settings → Windows Update → Update history and look at what actually failed
If the failures are a named Feature update to Windows 11, version … — this guide is your fix
If ordinary monthly (KB) updates are failing with error codes, that is a different problem (update cache or disk issues), not the hardware check — the bypass is not involved
Also ignore the PC Health Check app if it still calls your PC unsupported. It will always say that. It is a report, not a block on monthly updates

The Fix — Microsoft's Own Upgrade Key, Then In-Place Upgrade
For upgrades, Microsoft itself documents a registry value that tells Setup to proceed despite an unsupported TPM or CPU. It was published for IT admins, with warnings — respect them below.
Back up anything critical first. A version upgrade is a major operation on any PC
Open Command Prompt as Administrator and run the command shown in the panel above: it creates AllowUpgradesWithUnsupportedTPMOrCPU under HKLM\SYSTEM\Setup\MoSetup
Download the new version's ISO from Microsoft, right-click it and choose Mount
Run setup.exe from the mounted ISO and choose Keep personal files and apps when asked — this performs an in-place upgrade, not a wipe
The compatibility screen now shows Microsoft's warning text about unsupported hardware instead of a hard stop; accept it and the upgrade proceeds

The Alternative — the LabConfig Keys Before Setup
The same LabConfig values Ventoy uses for clean installs can also be added to your running Windows before launching the ISO's setup.exe — Setup reads them during its check. The MoSetup route above is the cleaner documented one for upgrades, but if a build resists it, adding the five LabConfig values (BypassTPMCheck, BypassSecureBootCheck, BypassCPUCheck, BypassRAMCheck, BypassStorageCheck, each DWORD 1 under HKLM\SYSTEM\Setup\LabConfig) before running setup.exe is the known second route. The manual LabConfig guide in this series lists every value exactly.

What to Expect Every Year
Monthly updates: nothing to do — they keep working
Each yearly version: expect to repeat the in-place upgrade routine above with the new ISO
Keep your Ventoy stick current — its bypass remains your tool for clean installs, while the MoSetup key is the tool for upgrades of an installed system
⚠️ Honest note: Microsoft's own wording for the MoSetup key says upgrades on unsupported hardware are allowed but not recommended, and that such devices are not guaranteed to receive updates. In practice this routine has worked version after version — but you are maintaining this PC outside Microsoft's support promise, and a backup before each upgrade is not optional.

Will the in-place upgrade delete my apps or files?
No, provided you choose Keep personal files and apps at the setup prompt. If that option is greyed out, stop — it usually means the ISO language or edition does not match the installed Windows, and continuing would force a clean install.
My Windows Update shows the feature update but it fails during install. Same fix?
Yes — that is the compatibility check failing mid-upgrade. Leave Windows Update's copy aside and do the ISO in-place upgrade with the MoSetup key in place; it is the same upgrade, driven manually.
Do security updates ever get blocked on a bypass install?
Monthly security and cumulative updates do not run the hardware appraisal, and they install normally on bypassed systems. Nothing is guaranteed by Microsoft — that is the honest position — but the blocked item people actually meet is the yearly feature upgrade, not the monthly patches.
