[WCP] CEF window does not show up when wcp is installed in Program Files

[speedbooster]

Problem

CEF UI does not show up when the wcp is installed in the Program Files folder.

Steps to reproduce

1. Install the package in Program Files (default path)
2. Lock the windows and try to use the authentik windows credential provider (click the Sign In button)

Expected behaviour

CEF window should launch upon clicking the Sign In button in wcp

Additional information

The log file indicates that the CefDeleteCookiesCallback prior to launching the CEF UI is not triggered.
The issue is likely due to the Program Files being a protected path even though the wcp has system access due to the windows logon process. Could it be that the cefexe CEF subprocess is not launched with the same privileges and so unable to overwrite the cookies file(s)?

From testing, cefexe runs as SYSTEM too, but we should avoid writing to that folder anyways

I can say it's still on going issue for this. No browser window is showing up after commit 5e1cb08.
