Recently I asked a question about whether it's safe for me to install an optional update (from a Windows Update notice), that was for "Realtek PCIe GBE Family Controller". (I have Windows 7, HP laptop, wired, ethernet cable with DSL.) I got 2 replies to my question: one said yes install it, the other said no don't do it, in fact turn off Windows updates. So now I'm wondering if there's a knowledgeable person who can break that tie.
Also, I saw a post in this Community from Aug. 2015 about a Windows 10 user experiencing VERY SLOW upload speed and he found it's related to Realtek PCIe GBE Family Controller. Saw another user (Windows 7) commenting about similar problems, but that post seemed to be 2012.
Is it SAFE for me to install it?
