Windows 10 or Windows 11 - what's the difference?

Windows 11 brings a more modern design, longer support, and higher security requirements. As of October 2025, Windows 10 will no longer receive regular security updates and is only a temporary solution for older hardware without TPM 2.0.

Pro or Enterprise LTSC - which edition do you need?

Pro receives semi-annual feature updates and is suitable for most business PCs. Enterprise LTSC freezes the feature set and only provides security updates - ideal for point-of-sale systems, manufacturing controls, and other devices that should not be touched.

Rent or buy a Windows license?

Rental and leasing models are usually only worthwhile for larger company fleets. For private users and small businesses, a one-time purchase - ideally used - is the most economical solution.

Windows 10 is out of support – what now

As of October 14, 2025, Windows 10 will no longer receive regular security updates. Anyone still using it should plan their transition to Windows 11 now – or consider the ESU program as a temporary bridge.

Windows 11 System Requirements Explained Simply

TPM 2.0, UEFI Secure Boot, and a modern processor are mandatory. Microsoft's free PC Health Check app will tell you in seconds if your device is ready.

OEM, Retail, or Volume License?

OEM licenses are tied to specific devices, retail licenses are freely transferable, and volume licenses are intended for businesses with many devices. For most users, a retail full version is the most flexible choice.

Activate license key - here's how

Press Windows key + I, navigate to Activation, enter the 25-digit key - your license will be active in a few seconds.

Windows 7 in 2026 - Time to upgrade?

Since 2020, Windows 7 no longer receives security updates - a real risk when using the internet. An upgrade to Windows 11 is long overdue.

Windows Licenses for Students & Higher Education

First, it's worth checking your own university portal - many universities offer affordable licenses. For anything beyond that, a verified, pre-owned license is the most budget-friendly solution.

Kurz & knapp

Common questions about Windows licenses

Is Windows 11 free if I already have Windows 10?

The free upgrade offer was time-limited and has since expired. You currently need a valid Windows 11 license.

Can I transfer my Windows license to a new PC?

For retail full versions, yes; for OEM licenses, usually not – they are tied to the original device.

What happens if I don't activate Windows?

Windows will continue to run, but will display a watermark and restrict some personalization options.

Do I absolutely need a Microsoft account for Windows 11?

With Windows 11 Home, a Microsoft account is mandatory for the initial setup; with Pro, this can be bypassed.

How long does delivery take after purchase?

You will usually receive your license key by email within a few hours.

Is a used Windows license as secure as a new one?

Yes - it is the same full-featured software with all security updates.
