How to disable pre-launching and pre-loading so CCleaner can fully clean Edge

Recommended Posts

When I tried to clean my PC and my laptop today.  I was alerted to the fact that CCleaner could not fully clean EDGE because of certain settings controlled by the registry and/or group policy.  I was linked to the following page https://www.ccleaner.com/docs/ccleaner/troubleshooting/how-to-disable-pre-launching-and-pre-loading-so-ccleaner-can-fully-clean-edge which gave instructions on how to change the registry to avoid this problem.  However, when I tried following the instructions for the registry changes on my laptop the registry key mentioned does not exist. Specifically the MicrosoftEdge key in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main is not present.  I had changed my settings on my Windows 10 Pro desktop by following the group policy instructions but the same key is not there on that machine either.  Both my laptop and desktop are Windows 10 1809.  Can anyone enlighten me on what to do since the instructions are in error?

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. Save the information in the code below as a .REG file, example:
Microsoft Edge Browser - Disable Pre-Loading.reg

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

 

Then  double-click the .REG file, allow the UAC prompt, and then it will be imported.

Then there's also this:
Internet Explorer and Edge will typically (at least in my case) have no issue being cleaned if you do the following:
1. Start Microsoft Edge.
2. Immediately close Microsoft Edge.
Side Note: Do not End Task Microsoft Edge from within Task Manager since doing that "may corrupt its databases."
3. Clean with CCleaner. It will spend a few seconds cleaning Internet Explorer however it should be able to successfully clean both it and Edge without any error text stating they're being skipped.
