Windows 10 asking to register for Dropbox

A client has a computer and has Windows 10 now installed. He keeps getting a pop up to register for Dropbox. He doesn't want Dropbox, how can we stop these messages?

I thought Dropbox client must be installed but when he went to uninstall programs in control panel there was no Dropbox app installed.

Remove Dropbox information from the Windows Registry (if there is any) , and retest.

You need administrator's permission to edit your registry.

1.Click the Start button. Type REGEDIT in the search box and press Enter.
2.In the Registry Editor, drill down until you find the ks key following this path: HKEY_CURRENT_USER\Software\Dropbox\ks
3.Right click ks and select delete.
Does your client have Dropbox on another machine?  If not, then I agree with the first post here that the request is probably malware.

Is the pop up a desktop window pop up (not likely Dropbox) or an Action Center pop up (which is where my own Dropbox shows up)?
If Dropbox not in Add/Remove use this script (save as .BAT file)

@echo off
setlocal EnableDelayedExpansion

if exist "%ProgramFiles(x86)%\Dropbox\Client\Dropbox.exe" (
echo Dropbox found. Uninstalling..
"%ProgramFiles(x86)%\Dropbox\Client\DropboxUninstaller.exe" /InstallType:MACHINE /S
)

if exist "%ProgramFiles%\Dropbox\Client\Dropbox.exe" (
echo Dropbox found. Uninstalling..
"%ProgramFiles%\Dropbox\Client\DropboxUninstaller.exe" /InstallType:MACHINE /S
)

if exist "%ProgramFiles%\Dropbox" (
echo Removing "%ProgramFiles%\Dropbox" directory..
rd "%ProgramFiles%\Dropbox" /Q /S
)

if exist "%ProgramFiles(x86)%\Dropbox" (
echo Removing "%ProgramFiles(x86)%\Dropbox" directory..
rd "%ProgramFiles(x86)%\Dropbox" /Q /S
)

set sw=HKLM\SOFTWARE
set u=Microsoft\Windows\CurrentVersion\Uninstall
set k=Dropbox
if not "%ProgramFiles(x86)%"=="" set x=Wow6432Node\
reg query "%sw%\%x%%u%\%k%" > nul 2>&1
if !errorlevel!==0 (
echo Deleting %k% registry key..
reg delete "%sw%\%x%%u%\%k%" /f
)

echo Detecting Dropbox updater
reg query "%sw%\%x%%u%\{099218A5-A723-43DC-8DB5-6173656A1E94}" > nul 2>&1
if !errorlevel!==0 (
echo Uninstalling Dropbox updater
%systemroot%\system32\msiexec.exe /X {099218A5-A723-43DC-8DB5-6173656A1E94} /qn
) else echo Dropbox updater not found!

endlocal

Check for sure that Dropbox is not installed. Attempt to remove causes issues if Dropbox is open or running at the time.
Script uses uninstaller that closes Dropbox first
if above suggestions didn't fix the problem then please post a screenshot of that message or let us know the exact message.
