Difficulty: MediumTroubleshooting Windows Performance and Application Crashes

A user reports that a custom inventory management application freezes and stops responding whenever large database reports are executed. Place the troubleshooting steps in the correct order to identify and resolve the blocking process causing the application freeze.

  1. 1Open Task Manager using Ctrl + Shift + Esc to check overall CPU and memory metrics and locate the frozen application status.
  2. 2Launch Resource Monitor from the Performance tab to analyze detailed process threads and queue behaviors.
  3. 3Right-click the non-responsive application process on the CPU tab and select Analyze Wait Chain.
  4. 4Terminate the specific blocking process identified in the wait chain tree to resolve the application hang.

Answer

The correct troubleshooting sequence is: 1) Open Task Manager using Ctrl + Shift + Esc to view resource usage, 2) Launch Resource Monitor from the Performance tab, 3) Right-click the non-responsive process and select Analyze Wait Chain, and 4) Terminate the specific blocking process identified in the wait chain tree.
The proper administrative workflow begins with establishing basic process visibility in Task Manager, advancing to Resource Monitor for detailed thread inspection, executing Analyze Wait Chain to discover dependent deadlocks, and finally terminating the blocking process to restore application functionality.

Step-by-Step Solution

1
Press Ctrl + Shift + Esc to open Task Manager.
Task Manager opens, displaying basic system utilization metrics and identifying which processes are listed as 'Not Responding'.
Establishing initial diagnostic visibility allows the technician to confirm system state before performing deeper analysis.
2
Open Resource Monitor from the Performance tab.
Resource Monitor opens, granting access to process-level thread queues, disk activity, and wait chain analysis.
Task Manager shows summary data, but Resource Monitor provides the advanced thread analysis needed to diagnose process deadlocks.
3
Right-click the hanging process under the CPU tab and click Analyze Wait Chain.
A window opens displaying the process thread tree, highlighting any subordinate or sibling process holding locked resources.
Wait Chain Analysis pinpoints the precise secondary thread or process causing the primary application to freeze.
4
Select the blocking process PID shown in the wait tree and end the process.
The blocking thread releases locked handles, allowing the primary application to resume execution or close cleanly.
Targeting the specific blocking dependency resolves the deadlock without abruptly terminating un-saved application data unless necessary.
