[QUOTE="Andy Ful, post: 544366, member: 32260"] I updated my poor knowledge of vbs scripting. There's no need to use wrappers or launchers to elevate (but still this is the convenient way). I created an example of "Run As SmartScreen" solution using only vbs scripts (see below for attached files). I've also noticed recently that "Run As Admin" works well with default deny SRP when value of SRP DefaultLevel=0. If DefaultLevel=20000 then SRP cannot protect removed script extensions (see post #14 in [URL='https://malwaretips.com/threads/software-restriction-policies-to-windows-home.63530/']Secure Windows - Software restriction Policies to Windows Home[/URL] ) If the "Run As SmartScreen" setup was made for the inexperienced user, some system hardening is needed: 1. [URL='http://smallvoid.com/article/winnt-removable-storage.html'][COLOR=#0059b3]Restrict access to removable disks [/COLOR][/URL](default -> "Deny_Execute"=dword:00000000) [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\RemovableStorageDevices\{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}] "Deny_Execute"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Storage] "Deny_Execute"=dword:00000001 2. [COLOR=#0059b3]Hide "Run As Admin":[/COLOR] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer] "HideRunAsVerb"=dword:00000001 Removable disks may have non NTFS format, so files lose alternate data streams there and cannot be checked by the SmartScreen. The user may accidentally choose "Run As Admin" instead of "Run As SmartScreen". [/QUOTE]
