To allow CCleaner to properly clean Edge without an error dialog displayed by CCleaner these keys must be present in the registry to prevent Edge from pre-loading, the keys do not exist by default and have to be created.

1. Copy the information in the code below, and paste it into an empty Notepad window.
2. Save the file in your documents folder using the following file name including the quotes:
"Microsoft Edge Browser - Disable Pre-Loading.reg"
3. Double-click the .REG file, allow the UAC prompt, and then it will be imported. You "may or may not have to restart your computer" for the change to apply.

Windows Registry Editor Version 5.00

; Microsoft Edge browser disable pre-loading after Windows 10 (October 2018 Update).
; This allows CCleaner to properly clean Microsoft Edge after Windows 10 (October 2018 Update).

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge]

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main]
"AllowPrelaunch"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\TabPreloader]
"AllowTabPreloading"=dword:00000000

 

This did not work for me, even after creating the keys. Copying the info above into a reg file gave me an error. See image
