[NAME]  Lots of other threads about major problems with the XPS 8930 BIOS 1.1.27 update so read some of them. And be thankful it didn't install on your PC. Immediately go into BIOS setup (F2 at boot) and disable UEFI Capsule Updates which should prevent Windows Update from installing this update without warning or permission. You didn't mention what BIOS version you have now, but if it's recent (eg, 1.1.26) stay there. Do not let 1.1.27 get installed. Dell has been informed about the problem, so hopefully they'll release a new update without the problem.
I went to Dell.com to download the 1.1.27 BIOS update for my XPS 8930 running Windows 11. I double-click the XPS8930_1.1.27.exe file, and it comes up with an error. "Error: Driver Version Fail!" I click okay and then it exits. [IMAGE]
