I got offered that same BIOS update for my XPS 8930 by Windows Update a while back, even though I also already have v1.1.15 installed.  I suspect it's because somebody stuck 0. in front of the version number so WU thinks it's new/different than 1.1.15.

BTW: Dell just released v1.1.16 for XPS 8930 to fix another round of Intel security flaws. So sooner/later WU will probably be offering 0.1.1.16 to you, even if you already do this update yourself.

Don't know why System Restore gets turned off. Haven't seen that here. Major updates to Win 10, like going from 20H1 to 20H2 will delete all existing restore points because they won't work and could corrupt the system.

Did you click the Configure button on the Restore screen and make sure System Protection is enabled and set the disk space usage to something >0%?

You should already know that Microsoft doesn't care what people like or do because only they know what's "good" for us and we don't...

I just reinstalled Windows and I turned on System Restore after I installed 20H2. Yes  I used Dell Support Assist to reinstall and it installed 1903. So I upgraded to 20H2 no big deal for me some people do like clean installs I know.

But I just checked and System Restore is still on after running all the Windows Updates. I will keep an eye on it maybe the issue was addressed. It is set at 9% 19.4 GB is used. 

As for the BIOS I installed it because I figured it was going to keep bugging me. And Support Assist did find some Dell Updates I haven't looked yet to see which ones.  

I guess that is why Microsoft is providing BIOS updates because of the security thing. 

FWIW, I just installed the new BIOS v1.1.16. Did it using a (non-bootable) USB stick with the BIOS .exe file on it, via the Flash Update option on the F12 menu at boot.

Scared me half to death because I got a "disk error check" warning when PC started to reboot the final time. Turns out Windows decided there was some issue with that USB stick and fixed it. So why didn't it warn me when I copied the file onto the stick before I used it for the BIOS update...???

But the new version is installed and working okay...

There should be a BIOS option that controls whether BIOS updates are allowed from Windows-Update. IIRC, it's called "Capsule Updates".

Yeah, Legacy Control Panel and other things are being slowly depreciated and moved to Settings.

Still, try to keep going forward with Updates (not backwards).

@RoHe 

I think I will do the update later on. I just looked on the support site for my system. The new BIOS was listed yesterday. But when I ran Support Assist it was not showing as a option. I am going to eventually uninstall Support Assist. Because it is a useless tool that never works right.

@Tesla1856 

I will look but I don't think my BIOS has that option. Maybe the option is added in a BIOS update.

The XPS 8930 Service Manual lists UEFI Firmware Capsule Updates as a BIOS option. My XPS 8930 with i7 CPU has that option enabled (default).

When WU offered BIOS "0.1.1.15", I just told it to hide it and not offer it again. It hasn't...

@Tesla1856 

I have looked in the BIOS and do not see anything called Capsule Updates. 

@RoHe 

As of right now System Restore has not turned off. Must have been something in the last install turning it off.

@CTG_8273  Sure you looked in the right place in BIOS setup?

My XPS 8930 has i7-9700 CPU and BIOS v1.1.16 shows this on the Security tab:

@RoHe 

I just found it I didn't even see you posted an image. I rebooted to the bios and looked. And there was UEFI Firmware Capsule Updates.

If Windows Update used the same version numbers as Dell uses, I bet WU won't offer an update when you already have that version installed.

But as long as WU offers the option to ignore/hide the update, it -probably- can't hurt to leave the Capsule Update option enabled.
