The primary driver is the licensing model. Word 2010 falls under the "perpetual license" category. You bought it, you owned it. In contrast, modern Microsoft Word requires a monthly or annual subscription. For users who only need basic word processing, the recurring cost of Microsoft 365 is unjustifiable.

To install the 64-bit version of Word 2010, you must explicitly select it from your installation media, as the 32-bit version is often the default.

But a pressing question echoes through forums and IT departments daily: Can you install and run Microsoft Word 2010 on a modern Windows 10 64-bit system?
