How can attackers clear file execution records from the Windows registry without leaving traces?

To clear ShimCache records, an attacker can export the registry key before a system reboot and reimport it afterward, as ShimCache only updates on reboot. Alternatively, an abnormal shutdown can skip the registry write operation. For UserAssist, MUICache, RunMRU, and AppCompatFlags, attackers can simply delete the corresponding registry key values. However, these operations may themselves be logged. For stealthier approaches, consider techniques described in Penetration Techniques - Stealth Execution of Windows Remote Assistance or Penetration Techniques - Deletion and Bypass of Windows Logs.
