This adapter is considered legacy (launch 2008), so it is supported only by built-in drivers in Windows 8.1 upwards.
I bought this card as I was having troubles with my on-board LAN. Thinking Intel was the best way to go, only to discover afterwards that Intel doesn't support the card anymore and I'll have to stick with the default Windows 10 drivers...
Really a shame, it's about the most popular LAN card on the market...
Guess I'll have to look for an alternative. Does Intel have an alternative PCI-Express gigabit desktop adapter available which IS supported by Intel in Windows 10?
