1. What HMP A does mean ? Is this an antivirus ? Try to add wfc.exe in the white list of it. 2. If you kill wfc.exe from Task Manager and launch it again, does it work ? 3. The WFC icon from the system tray area contains an exclamation mark or does it show the profile ? 4. What do you mean by "annoying delay in internet availability at start up but then I get that with Advanced Settings used in the naked WF at times as well". While you have WFC enabled your network initialization takes longer ? Even if you use Low Filtering profile ? 5. Was the operating system installed from scratch or was it updated from a previous version of Windows ?
