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

Recent Microsoft updates have introduced pre-loading (v10.0.1802) and pre-launching (v10.0.1809) which means that
CCleaner is temporarily unable to clean all Edge files and folders.

For more information on pre-launching and pre-loading please see Microsoft's documentation.

We’re working on a fix right now but in the meantime, please follow these instructions to disable these features
and ensure that CCleaner can fully clean Microsoft Edge Forms, Saved Cards, Set Aside Tabs and Session data.

Pre-launching and Pre-loading can be disabled either via Group Policies or the Windows Registry.
Please see the instructions for either method below.


1.)  How to disable via Group Policies

  1. Click right the Start icon and in the 'Run', type ‘gpedit.msc’ and hit enter to open the Group Policy Editor
  2. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Microsoft Edge

  3. Find and double-click on the policy called ‘Allow Microsoft Edge to pre-launch at Windows startup, when the system is idle, and each time Microsoft Edge is closed’
  4. Set the policy to ‘Enabled’
  5. Under ‘Options’ you’ll see a ‘Configure pre-launch’ dropdown. Please select ‘Prevent pre-launching’

  6. Find and double-click on the policy called ‘Allow Microsoft Edge to start and load the Start and New Tab page at Windows startup and each time Microsoft Edge is closed’
  7. Set the policy to ‘Enabled’
  8. Under ‘Options’ you’ll see a ‘Configure pre-launch’ dropdown. Please select ‘Prevent pre-launching’

  9. Once complete, you will need to log out and back in again for the changes to take effect

NOTE:
If you are running Windows Home Edition you will not have access to Group Policies and therefore will only be able to disable via the registry (see below)

    3. Name it AllowPrelaunch
    4. Double-click on ‘AllowPrelaunch’ and ensure its value is set to 0
