Preparation
Windows 11 readiness checklistCheck firmware, storage, drivers, backups and Microsoft requirements before setup.Back up before a Windows 11 upgradeCreate recoverable file, system and key backups before changing the installation.Create a Windows recovery drivePrepare bootable recovery media and verify that the PC can start from it.Save the BitLocker recovery keyLocate, export and verify the recovery key before firmware or boot changes.Check TPM 2.0 statusInspect TPM availability and firmware settings without assuming a bypass is appropriate.Check Secure Boot statusVerify UEFI and Secure Boot state and document the original configuration.UEFI vs Legacy BIOS before upgradingIdentify boot mode and partition dependencies before changing Windows setup.Free space for a Windows 11 upgradeEstimate working space, remove low-risk clutter and preserve rollback capacity.Back up Windows drivers before upgradingExport third-party drivers and record device versions for recovery.Read a Windows 11 compatibility reportTurn compatibility findings into a supported, unsupported or postpone decision.
Installation

Security
Verify a Windows download sourceUse source, HTTPS, publisher context and malware scanning as separate trust signals.Understand Microsoft Defender SmartScreenInterpret reputation warnings without treating them as proof of safety or malware.Security baseline for an unsupported PCPreserve updates, encryption, backups and least privilege where support is limited.Firmware change safety checklistRecord settings, power the device reliably and know the recovery route.
Method and primary sources
The editorial team separates product generations, checks statements against the developer repository and Microsoft documentation, and avoids guaranteeing outcomes on untested hardware. Procedures are written to preserve evidence and recovery options before changes are made.
