Auto Close Idle Client 4.3

Auto Close Idle Client by Ultimate Net Tools is a lightweight utility that automatically detects and closes inactive client sessions and applications, helping organizations enforce idle-time policies, free up licenses, and reduce unnecessary resource usage. Designed for IT administrators managing shared systems, remote sessions, and license-limited software, it streamlines housekeeping tasks while improving security and compliance.

The tool monitors user and application activity, then applies customizable rules to close or disconnect idle clients after a defined threshold. You can tailor behavior by application or process, set different schedules for work hours versus after-hours, and create exceptions for critical tools that must remain running. To prevent accidental data loss, Auto Close Idle Client can warn users with a countdown and provide a grace period before closing, with the option to force-close only when necessary.

Detailed logging and clear activity reports support audits and help you fine-tune policies over time. With a small footprint and straightforward configuration, Auto Close Idle Client fits easily into existing environments, from shared workstations and computer labs to VDI and remote desktop hosts. The result is a cleaner, more secure, and more efficient environment—without constant manual intervention.
