Remediation Steps:
Isolate the endpoint from the network immediately. Run a Microsoft Defender Offline scan to remove the threat. Manually remove persistence by deleting the 'winupd' Run key from the registry (HKCU) and the 'winupd.vbs' file from the Startup folder. Due to RAT capabilities, change all user passwords and consider reimaging the device.
