Location is greyed out, i cannot remove internet explorer 11 addon after virus removal

There's at least a ghost of a chance the missing file we need - to restore Location functionality to you (& even Services functionality for Geolocation) - is named in CBS.log. I see you posted the top of that log, but this is what I need to see (as posted earlier).

Note: To copy the name(s) out, highlight the name - i.e., drag the pointer over it while pressing down on the left side of the touchpad. Then, R-Clk the highlighted name, & select "Copy".

Note: If it doesn't work using "Cannot repair member file", then try "missing".

          If you can find neither - geez, I guess I must ask that you run "SFC /Scannow" again.

          The output from the first run may have been wiped by the recent Windows Updates,

           which write to the same CBS.log file...

(a) Open Explorer to "C:\Windows\Logs\CBS"

     This is the folder that holds "CBS.log".

(b) R-Clk "CBS.log", & select "Open", (or D-Clk "CBS.log").

     It's large - may take several seconds to open.

(c) Click the "Edit" Menu, & select "Find".

     The find requestor appears.

(d) Type or paste "Cannot repair member file" into the find box, & hit ENTER.

     Should get you to something like this...

2007-01-12 12:10:42, Info                  CSI    00000008 [SR] Cannot

repair member file [l:34{17}]"Accessibility.dll" of Accessibility, Version =

6.0.6000.16386, pA = PROCESSOR_ARCHITECTURE_MSIL (8), Culture neutral,

VersionScope neutral, PublicKeyToken = {l:8 b:b03f5f7f11d50a3a}, Type

neutral, TypeName neutral, PublicKey neutral in the store, file is missing

(e) Copy the name, & post it. Then, Find Next (use the Edit menu or F3, maybe with FN), & post each one found.

Note: I've made the file name bold, & underlined the choice of find strings. Your name(s) will be in that same position - pretty close to the find string.

I'm going to study your DISM output. There's at least another ghost of a chance we can cure you by curing that DISM report!

This is what I have....

I understand. There have been threads about difficulties doing a reset, too. You could be braver with a system image on hand to recover what you've got should the reset go bad. I've got a Seagate Slim 2 TB external hard drive with several images on it, Win 8.1 & Win 10. Of course, there are threads about system images that won't restore, too. But that makes two things that need go wrong for total disaster. Three things, if you've taken the Win 10 ISO download which can do a fresh install...

Also, you might have a factory recovery image of Win 8 somewhere on your hard drive. Mine on partition 7 would get me back to Win 8.1...

...In fact, it already did it once. About a week after I bought this Dell Inspiron 3542, I locked myself out by inadvertently changing my password. It wasn't fun - because clicked icons & buttons often gave no feedback & took time to get to the next step - but the Dell procedure did work.

So, I clicked to turn location off in Action Center. Cortana changed its icon from...  to . It displayed a message that it would help to turn it back on, & it had diminished usefulness - but still worked. I could still get it to find an app by typing its name. I could still ask Cortana, even for the weather. It would BING for it. But I couldn't talk to it, & it wouldn't grab the weather & stuff & put it in its display, like...

(1) You don't see that stuff in Cortana, do you?

(2) So, what are the missing files in SFC.log?

(3) Did you run the DISM?
