Allow me to throw the first guess here.  It's probably the device extension for Realtek Audio driver 6.0.9481.1, A51
Machine is a Dell 8950 desktop running Windows 11 Home, 22H2. I went to shut done the pc, and there was a message that there was an update waiting to be installed. Without looking to see what the update was, I said update and restart. My mistake. I looked at the update history, and the only entry today was under drivers. All the entry said was, "Dell - Extension - 1.7.2.563". I couldn't find anything about this driver. Anyone know? Machine is running fine.
XPS 8950, what is Dell Extension 1.7.2.563?
