Final answer:
The users did not reboot the computer after the patches were deployed.
Step-by-step explanation:
The MOST likely scenario in this situation is that the users did not reboot the computer after the patches were deployed. When patches are installed on a Windows-based machine, a reboot is often required for them to take effect. If the users did not reboot their computers after the patches were deployed, the vulnerabilities that the patches were meant to address may still exist, leaving the machines susceptible to exploits from threat actors.
To ensure that the patches are properly applied, it is important for users to reboot their computers after the patches are deployed. This allows the operating system to load the updated files and configurations, effectively addressing the vulnerabilities.
If the users have rebooted their computers and the exploits are still occurring, it may indicate a deeper security issue such as malware infection or compromised credentials. In such cases, additional investigation and remediation steps would be necessary.
