So I received an error message for a bunch of the re-register commands…

The module “browseui.dll” was loaded but the entry-point DSllRegisterServer was not found….

The ones below are the ones that received this error and of course I have no idea what it means

msxml.dll
mshtml.dll
shdocvw.dll
broweui.dll
gpkcsp.dll
sccbase.dll
slbcsp.dll
initpki.dll
wuaueng.dll
wuaueng1.dll
wucltui.dll
wuweb.dll
qmgr.dll
gmgrprxy.dll
wucltux.dll
muweb.dll
wuwebv.dll
Fortunately my laptop booted without issues but I still can’t install KB5007186 although all other updates seem to work okay.
