During the 2026 back-to-school period, consumers can take advantage of discounted Microsoft software and operating systems through Keysfan, an online reseller based in Hong Kong. The company offers a range of Microsoft products at significantly reduced prices, making them more accessible for students and budget-conscious buyers. Windows 11 operating system keys are available for less than 15 euros, with specific versions priced at 13.15 € for Windows 11 Home, 13.25 € for Windows 11 Pro, and 12.80 € for Windows 11 Enterprise LTSC 2024. Microsoft Office 2024 Professional keys start at 19.99 €, while older versions like Office 2019 Professional Plus and Office 2021 Professional Plus are available for 24.95 € and 28.48 €, respectively. Keysfan also offers bundled deals that include both a Microsoft Office suite and a Windows operating system, starting at 32.25 €. The CLUB62 promo code provides a 62% discount on these bundles, further reducing the cost for buyers. However, users are advised to check their device compatibility before purchasing, as not all licenses may work with every system. Keysfan delivers product keys via email and provides 24/7 customer support, which is highlighted in its 4.8/5 rating on Trustpilot. Despite its popularity on consumer review sites and forums, Keysfan has raised some concerns about transparency. The company does not disclose the origin of the product keys it sells, and most of its licenses are OEM (Original Equipment Manufacturer) versions, which are typically intended for pre-installed software on new computers. Additionally, VAT (Value Added Tax) does not apply to orders placed within Europe, which can make the prices even more attractive for European buyers. The company is favored for its competitive pricing, with discounts on the latest Office software reaching up to 90% off retail prices. However, the lack of clarity about the source of the keys and the nature of OEM licenses may be a concern for some users. As with any software purchase, buyers should ensure that the licenses they receive are compatible with their devices and meet their specific needs.
