I am having a problem with Explorer replacement. In Preferences 'Replace Explorer for all folders' is selected. I am using financial software called YNAB4 version 4.3.857. This has a facility to export an account in .qif format to my Dropbox account. At the end of the export process there is an option to open the output folder (i.e. Dropbox). Until yesterday whenever I selected this option it would open in Dopus. Now it will only open in Windows Explorer. If I open Dropbox from the start menu it opens in Dopus.
There is one change I have made to my laptop which might have caused this. I was having a problem with being unable to browse for a picture for my lock screen. After trying many solutions suggested online I eventually found one that worked here:
tenforums.com/windows-update ... tings.html
which involved deleting registry keys:
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKCU\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKCU\Software\Policies" /f
reg delete "HKLM\Software\Microsoft\Policies" /f
reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsStore\WindowsUpdate" /f
reg delete "HKLM\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKLM\Software\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\WindowsStore\WindowsUpdate" /f
Could this be the cause of the problem?
