Häufig gestellte Fragen

How do I activate my Windows 10 Professional key?

Activation is really simple:

  1. Open Windows Settings (Windows + I)
  2. Go to "Update & Security"
  3. Select "Activation"
  4. Click "Change product key"
  5. Enter your 25-character product key
  6. Follow the activation instructions

Activation happens automatically when you are connected to the internet.

Is the Windows 10 Professional key a perpetual licence?

Yes. The Windows 10 Professional key is intended for permanent use and incurs no monthly or annual subscription costs.

After successful activation you can use Windows 10 Professional permanently on the activated device. After major hardware changes, especially replacing the motherboard, re-activation may be required.

Can I install Windows 10 Professional on several PCs?

No, each Windows 10 Professional licence is intended for one PC. If you want to use Windows 10 Professional on several computers, you need a separate licence for each PC.

We offer suitable volume options for several devices. Volume discounts are available from just 3 licences.

Does Windows 10 Professional work on my old PC?

Windows 10 Professional runs without problems on many older PCs, especially if Windows 7, Windows 8 or Windows 8.1 is already installed and the device still works smoothly in everyday use.

For good performance we recommend at least:

  • Processor: 1 GHz or faster
  • Memory: at least 4 GB RAM recommended
  • Storage space: at least 32 GB free, preferably 50 GB or more
  • Graphics: DirectX 9 compatible graphics card
  • Display: at least 800 × 600 pixels

If your PC currently runs reliably with Windows 7 or Windows 8.1, there is a very good chance that Windows 10 Professional will work too.

On very old devices with little memory, a slow hard drive or less than 32 GB of free space, however, Windows 10 may run in a limited way or slowly. For better performance we recommend, where possible, an SSD and at least 4 GB RAM.

Tip: If you tell us your processor, RAM and free storage space, we can assess compatibility more precisely.

How long does delivery of my Windows 10 Professional key take?

With digital delivery you will receive your product key by email within 1-5 minutes of payment confirmation. With USB/DVD shipping, delivery takes 1-3 working days by post with a tracking number.

Can I reinstall Windows 10 Professional if I change my hardware?

Yes, your licence remains valid even if you change hardware. After major hardware changes you may need to re-activate by phone if Microsoft's activation system is triggered.

What is the difference between Windows 10 Home and Professional?

Windows 10 Professional includes advanced features that are not available in the Home edition:

  • BitLocker encryption for data protection
  • Remote Desktop hosting features
  • Hyper-V virtualisation technology
  • Group Policy management
  • Domain join functionality
  • Windows Update for Business controls

Is Windows 10 Professional safe for online banking and shopping?

Absolutely! Windows 10 Professional offers enterprise-level security for business and home users:

  • Windows Defender Antivirus with real-time protection
  • SmartScreen filter against phishing
  • Windows Firewall for network protection
  • Automatic security updates
  • Windows Hello for secure sign-in
  • BitLocker encryption for data protection

Microsoft invests over 1 billion dollars in the security of Windows 10 every year.

Which payment methods do you accept?

We offer you maximum flexibility when paying:

  • Credit card (Visa, MasterCard, American Express)
  • Bank transfer
  • Instant bank transfer/Klarna
  • Purchase on invoice (businesses only)

All payments are SSL-encrypted and secure.

Is there a money-back guarantee?

Yes. We want you to be happy with your purchase and to be able to use the software without any problems. If you have any difficulty activating or installing Windows 10 Professional, our customer service will support you quickly and with a focus on solutions.

Our aim is always to find a suitable solution so that you can use your software successfully. If this is not possible in an individual case, we will of course consider a refund under our guarantee terms.
