XPS 8900, BIOS Update 2.8.0 => Version 2.9.1 released February 3 2021
Has anyone installed the XPS 8900 BIOS Update, version 2.9.1 released 03 Feb 2021? It is an Optional update. "This update addresses the Intel Technical Advisory INTEL-TA-00391 and Intel Security Advisories INTEL-SA-00358, INTEL-SA-00381, INTEL-SA-00389."
Any problems or glitches during/after update? I searched the Community but didn't find any discussion for this particular BIOS update. Thanks!
Dell XPS 8900 System BIOS Version 2.9.1

Yes, Windows will update the BIOS unless you disable that in the BIOS settings. I believe it's labeled UEFI Capsule Updates (or similar). I also disable MS updating drivers in gpedit.

UPDATE: I discovered that BIOS 2.9.1 has already been installed on my PC. (I wonder if it happened during a Windows Update?)

Thanks for the reply. That's a good thought but I don't have Dell SupportAssist allowed to have free rein (I don't think).

@mangorunner - It also might have been installed by Dell's SupportAssist, if you have that running in the background.

Thanks for all the good information and excellent points.
I reviewed all of my Update history and I do not see the BIOS update listed. Perhaps I did install it myself and forgot.

@mangorunner - You're welcome.
It's really easy just to click and let an update get installed without even thinking about it. Been there, done that too!

@mangorunner Double-check SupportAssist and Dell Update settings.
If Windows Update installed it, I'd expect that BIOS update to be listed on the Windows Update "view update history" page and/or in the Windows Reliability Monitor on the date it was installed.
At least on my XPS 8930, Windows Update has only ever offered BIOS updates as "optional updates" and I have to click "View all optional updates" on the main Windows Update screen to see and select it. WU has never forced a BIOS update on my PC without warning and/or without permission. YRMV!
WU has offered them to me even though the same BIOS version was already installed, but WU thinks it's a different version because Microsoft typically puts extra 0's in file name which Dell's file doesn't have, eg WU offered BIOS 001.1.16 while it's listed as 1.1.16 on the XPS 8930 support page.
