I`ve just found a way to stop logging "informational" "Failed to connect to the driver: -2147023658". But you will need to see my entire quest to get the big picture...
First, I'm a user of Windows Insider Enterprise, which already gave me others problems in the past (with another softwares, not DropBox until now)...
On Windows Insider build 16215, I was facing some issues with keyboard, when using portuguese letters with accents (é ã á ...)... even with correct keyboard layout configurations... definily that wasn't a simple keyboard configuration issue....things goes more interesting when finding that using gmail with Chromre, I couldn't to use accented letters, but using gmail Edge I was able to use...
On another PC at working, I could move foward to Windows Insider build 16226, and this keyboard issue was gone...
Trying to move foward to 16226 on home laptop, I droped on this issue with Dropbox... for some reason, this issue with dropbox (error connecting to driver) seems to be impacting update process of build 16226, holding me up with bogus build 16215. The dropbox service itself was working normally, without issues.
Checking event viewer, I've found more then 200.000 entries about this "informational" error connecting to driver from dbxsvc. So I've to check this error on dropbox community.
Reinstalled dropbox, restarting service, tried everything that you already tried on this thread.
Reading previous replies on this thread, I was able to understand about different versions of dbx.sys (the driver wich dbxsvc service cannot connect). Using Process Hacker, I changed the FS driver entry to the dbx-dev.sys.
Restarted FS Driver and dbxsvc and BANG... new true "informational" messages:

After that, Windows update goes foward to build 16226 without issues.
I cannot double check if this issue with windows update is really related with dropbox FS driver, but I've found interesting to share.
Cheers,
