Windows 11 Pro: everything you need to know before installing the new version

Planning to upgrade to Windows 11 Pro? Whether for professional use, an upgrade from Windows 10, or a fresh installation, this guide explains everything you need to know before buying and installing Windows 11 Pro.


Why choose Windows 11 Pro?

Windows 11 Pro is the version of Windows designed for professionals, freelancers, and businesses. Compared to Windows 11 Home, it includes advanced features essential for work environments:

  • 🔒 BitLocker — full disk encryption to protect your sensitive data
  • đŸ–„ïžÂ Remote Desktop — access your PC from anywhere
  • 🏱 Join an Active Directory domain — integrate into a business network
  • ☁ Azure Active Directory — identity management in the cloud
  • đŸ§Ș Windows Sandbox — test apps in an isolated environment
  • ⚙ Hyper-V — native virtualization to run multiple systems
  • 📋 Group Policy Management (GPO) — centralized settings control
  • 🔄 Windows Update for Business — advanced update control

For personal or family use without these needs, Windows 11 Home is sufficient.


System requirements to install Windows 11 Pro

Before buying, make sure your PC meets Microsoft’s minimum requirements:

Component

Minimum requirement

Processor

64-bit, minimum 1 GHz, 2 cores or more

RAM

Minimum 4 GB

Storage

Minimum 64 GB

TPM

Version 2.0 required

Secure Boot

Must be enabled in BIOS

Graphics card

DirectX 12 compatible, WDDM 2.0 driver

Screen

Minimum 9 inches, HD resolution (720p)

⚠ The TPM 2.0 requirement is the most common blocker for installation. If your PC was bought after 2018, it likely has a TPM — but it may be disabled in the BIOS.

To check your PC’s compatibility, use Microsoft’s free PC Health Check tool before making any purchase.
