upgrade methods

Microsoft will cease support for Windows 10 on October 14, 2025. Users considering upgrading to Windows 11 may face obstacles due to hardware requirements, including TPM 2.0 and specific CPU models. Workarounds exist for upgrading incompatible PCs. To check compatibility: - Determine if the PC uses UEFI or Legacy BIOS via System Information (msinfo32.exe). - Ensure BIOS Mode is UEFI. - Check TPM status using the TPM Management tool (tpm.msc). - Verify CPU compatibility; most Intel CPUs from 2009 or later and AMD CPUs from 2013 or later should meet the standards. Option 1: Registry Edit Method (for PCs with TPM 1.2+ and UEFI) 1. Open Registry Editor (regedit.exe) as an administrator. 2. Navigate to HKEYLOCALMACHINESYSTEMSetup; create MoSetup key if absent. 3. Create DWORD (32-bit) Value named AllowUpgradesWithUnsupportedTPMOrCPU, set value to 1, and restart. 4. Download Windows 11 ISO from aka.ms/DownloadWindows11. 5. Mount the ISO file and run Setup.exe. Option 2: Using Rufus (for PCs without TPM or UEFI) 1. Download Rufus version 4.6 or later and Windows 11 ISO. 2. Prepare a USB flash drive (16GB or larger). 3. Launch Rufus, select the USB drive, choose the Windows 11 ISO, and check the box to remove requirements for 4GB+ RAM, Secure Boot, and TPM 2.0. 4. Create the bootable drive and run Setup.exe from the USB drive. These methods are unofficial workarounds. Users may encounter compatibility warnings, and the registry method is preferred for its simplicity. Some very old systems, especially those with AMD processors lacking SSE4.2 support, may still be incompatible.
