We have a work computer with activated Windows 11 Home. We need Windows 11 PRO to connect it to the company domain. There are many tips online on how to do this; I'm referring to the official source: https://support.microsoft.com/pl-PL/Windows/Deployment/Install-Upgrade/upgrade-windows-home-to-windows-pro Need detailed purchase instructions for installing Windows 11 Pro upgrade for a business company;

Need detailed purchase instructions for installing Windows 11 Pro upgrade for a business company; 6 questions concern the practical implementation of the above procedure:

"When Windows is updated through the Microsoft Store, it detects whether the current Windows 11 Home Edition installation has been activated and follows the appropriate instructions."

  1. Will I be asked to pay online for the upgrade?
  2. Do I need a company credit card to make the purchase?
  3. Will I receive a VAT invoice, and if so, what form will it take for accounting purposes? My company requires a document in the appropriate format, including: have a European Tax Identification Number (NIP) for VAT deduction,
  4. If point 3 is OK, how will the VAT invoice be delivered to me?
  5. If the purchase process is successful, will the license type be silently changed in the system - automatically, or are any manual actions required? Or receive  individual activation product Key ?
  6. If I successfully pay for the OS upgrade to PRO, will the update process be repeated for any reason?

    Hello Tadeusz,

    Thank you for posting question on Microsoft Windows Forum!

    Well! The following are the plausible explanations to your queries about installing Windows 11 Pro upgrade from Win11 Home version for a business company.

    Regarding the online payment for the upgrade. Once you navigate to Settings > System > Activation and click Go to the Store (or Open Store), the Microsoft Store app will open to the Windows 11 Pro upgrade page. To initiate the upgrade, you will be required to complete an immediate online checkout process for the upgrade fee (typically around $99 USD depending on your region).

    Microsoft Store accepts standard payment methods including credit/debit cards. You can use a personal card and submit the expense for reimbursement, but using a company card simplifies the process. Please note: Before clicking "Buy," ensure the Microsoft Account signed into that PC's Microsoft Store app is the one you intend to use for the business. If you use a personal Microsoft account, the license will tie to that individual's digital profile.

    For receiving a VAT invoice with my European Tax ID (NIP). If you are logged into the PC with a personal Microsoft Account, the Microsoft Store acts as a B2C (Business-to-Consumer) store. It generates a standard consumer receipt. To get a proper B2B VAT invoice with your European Tax ID (NIP), it is advisable to update your Microsoft Account Billing Profile with your company's full legal name, address, and NIP before making the purchase.

    For the VAT invoice. It is not sent automatically via email. After the purchase is processed (which can take anywhere from 48 hours up to 5 days before being available). You can find it by going to Microsoft Account Order History. Log in with the exact account used for the purchase. Locate the Windows 11 Pro Upgrade order and click Order details. Click Tax Invoice to download the official PDF for your accounting department. https://support.microsoft.com/en-us/accounts-billing/tax-invoices-breakdowns-and-registration-numbers-for-microsoft-store

    Once the Pro upgrade is installed and activated, it stays that way permanently on that device. You will not be asked to pay again or re-run the upgrade unless you wipe the PC. The digital license is bound to the hardware (and your Microsoft account).

    Hope the above information is helpful!
