How to install windows 11 on old hp laptop without usb?

For those wondering How to install Windows 11 on old HP laptop without USB or any external storage media, this method offers the most straightforward solution. A simple PowerShell script automates the entire bypass process—no need to manually edit the registry, create a bootable drive, or use any third-party tools.

It works by injecting a registry entry that instructs the Windows installer to ignore TPM 2.0 and CPU generation checks, then launches Microsoft’s official installation assistant.

Steps:

Open PowerShell as an administrator → Paste and run the following script:

New-Item -Path “HKLM:\SYSTEM\Setup\MoSetup” -Force

New-ItemProperty -Path “HKLM:\SYSTEM\Setup\MoSetup” -Name “AllowUpgradesWithUnsupportedTPMOrCPU” -Value 1 -PropertyType DWord -Force

Start-Process https://go.microsoft.com/fwlink/?linkid=2171764 -Wait→

The script will create a registry entry to bypass the restriction and download the Windows 11 Installation Assistant → Follow the on-screen prompts to complete the in-place upgrade. The entire process is performed within the Windows system, meaning no USB flash drive, no ISO image burning, and no BIOS settings changes are required. This is the solution to How to install Windows 11 on old HP laptop without USB—a fully automated, single-script solution.

Key Points:

• Fully automated; no manual registry editing required; no USB or external storage media needed; uses only built-in Windows tools.
• PowerShell must be run with administrator privileges; the upgrade still depends on whether Microsoft’s servers are providing the installation assistant for download.

For HP laptop users with older hardware and no spare USB drives, this PowerShell method eliminates all traditional obstacles, enabling a clean, in-place upgrade to Windows 11.
