Having a Active desktop recovery popup suddenly is very annoying, in particular it forces your desktop background turn completely white that hurt my eyes. Different fixes were found but only the following worked for me(as System Admin. disable me from disable the active desktop)
Update the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Desktop\SafeMode\Components
Change the value of DeskHtmlVersion to zero instead of decimal 272.
Than logoff and login again
