Direct answer
Review scheduled tasks against their business purpose, execution identity, trigger and executable path. Investigate unknown or overprivileged tasks with the owner before disabling or changing them.
Collect the task inventory
On an authorized machine, record task name, path, owner, state, triggers, actions and principal using the supported Task Scheduler interface or PowerShell tools. Note collection time and permissions. A task that has not run recently can still be needed for monthly processing or recovery.

Understand the action and identity
For an unfamiliar task that launches a script, identify the script's owner, expected location and business workflow. Check which account runs it and whether its permissions match that job's needs. Protect scripts and executable paths from unauthorized modification, and never record service-account passwords.
Investigate context
Compare the task with the device's software inventory, deployment records and vendor documentation. A task name alone is not proof of malware. Review trigger frequency, failure history and expected output with the application owner; preserve evidence if compromise is suspected and follow incident procedures.
Change and verify
Before disabling or changing a task, establish dependencies, a maintenance window and rollback. Test the approved job using safe inputs, verify the expected output and review subsequent scheduled runs. Record exceptions and their review dates rather than silently ignoring an unknown owner.
Assessment limits
A point-in-time task inventory cannot establish that all actions are safe or identify every persistence mechanism. Visibility depends on permissions and tasks can change after collection.
Frequently asked questions
Is an unknown scheduled task automatically malicious?
No. Determine its action, owner, identity and deployment source before classifying it.
Can I disable all tasks that have not run recently?
No. Some tasks run infrequently or support recovery; check dependencies and owners first.
Does a task's name establish what it executes?
No. Inspect the configured action and executable or script path in context.
