Have you tried rebooting your router and modem, if you have both? Are you using WiFi or Ethernet? There have been a couple of recent "Intel Corporation - Extension" updates (most recently - v3.1222.608.4, ‎on 8/‎26/‎2022 here) that were pushed by Windows Update (look in WU update history), that are actually updates for Killer Ethernet on the XPS 8930. (Intel bought Killer a while back.) This last update didn't actually update the Ethernet driver (v9.0.0.50), and supposedly only fixed a bug in the Killer Control Center app. I don't use KCC, so don't know if this latest update could be a problem. Also got "Intel Corporation - SoftwareComponent - 3.1222.608.4" update (8-31-22) which has the same number as the "Extension". No idea what this one is. I use Killer Ethernet without a router on my XPS 8930 with FiOS service, and haven't noticed any specific access delays. But, I did notice this last Extension re-enabled all the unnecessary Killer and xTend services listed in services.msc which I had previously disabled. So you may want to disable those, if they're enabled, and see if that helps.  I also disabled the Killer Intelligence Center app on the Startup tab in Task Manager, because I don't want/need that one either. So that's another thing to look at. Don't know if any recent Intel updates are for Killer WiFi because I have Qualcomm WiFi in my XPS 8930. So if you're using Killer WiFi, I can't help there...
Hi All, My XPS 8930 started to shut down very slowly (1.5 - 2.0 min) at the end of each day, about 5-10 days ago. (Fast boot up, about 21 seconds from the time the Dell logo shows.) I checked for updates and updated 3 "Urgent" updates, including Bios. But the problem persists. I have a pretty standard configuration: Win 10 Pro 21H2 (build 19044.1889), 32GB RAM, MS Office 2021 and other standard software, etc. Would greatly appreciate your advice. JF
XPS 8930, slow shut down
