Ever felt like your User Experience Virtualization (UE-V) settings are playing hide-and-seek? Files not replicating? Applications acting up? Don’t worry, we’ve all been there. The key to cracking these UE-V mysteries lies in debug logging. This guide walks you through turning on this powerful tool and deciphering its secrets.

What is UE-V Debug Logging and Why Should I Care?

UE-V debug logging is like putting a magnifying glass on your UE-V agent. It records everything the agent is doing, giving you a detailed history to troubleshoot when things go wrong. This is especially helpful when settings or files aren’t syncing correctly between machines.

Setting the Stage: Before You Begin

Before diving into the logging process, it’s crucial to identify what you’re trying to track. Are your applications misbehaving or are your desktop settings going haywire? These two scenarios require slightly different approaches. Also, keep in mind that traces collect data for all logged-in users. If you need to trace a non-admin account, you’ll either need to log in to a separate desktop session or launch a command prompt with elevated privileges.

Scenario 1: Unmasking Application Antics

Let’s say your favorite application isn’t behaving as expected. Here’s how to capture its activity with debug logging:

  1. Admin Power: Log in with an administrator account.
  2. Elevated Command Prompt: Right-click on the Command Prompt shortcut and select “Run as administrator”.
  3. Creating the Trace Definition: In the elevated command prompt, enter these two commands:
logman create trace UEV -P "Microsoft-User Experience Virtualization-App Agent" -ow  -o uevtrace.etl
logman update UEV -P "Microsoft-User Experience Virtualization-Agent Driver"
  1. Start the Trace: Type logman start UEV.
  2. Recreate the Issue: Close and relaunch the troublesome application. Do whatever you normally do that causes the issue to appear.
  3. Stop the Trace: After recreating the issue and closing the application, type logman stop UEV.
  4. Cleanup: Remove the trace definition with logman delete UEV.
  5. Decoding the Secrets: Convert the trace file into a readable format using this command: netsh trace convert uevtrace_000001.etl DUMP=TXT.

Scenario 2: Deciphering Desktop Setting Disasters

If your desktop settings are the culprit, follow these steps:

  1. Admin Privileges: Log in as an administrator.
  2. Elevated Command Prompt: Open an elevated command prompt (right-click Command Prompt and select “Run as administrator”).
  3. Trace Definition: Enter the same commands as in the application scenario:
logman create trace UEV -P "Microsoft-User Experience Virtualization-App Agent" -ow  -o uevtrace.etl
logman update UEV -P "Microsoft-User Experience Virtualization-Agent Driver"
  1. Start the Trace: Type logman start UEV.
  2. Trigger the Issue and Log Off: Perform the actions that cause the desktop settings problem, then log off.
  3. Log Back In: Log back into your account.
  4. Elevated Command Prompt (Again): Open another elevated command prompt.
  5. Stop the Trace: Type logman stop UEV.
  6. Cleanup: Delete the trace definition with logman delete UEV.
  7. Decode: Convert the trace file using: netsh trace convert uevtrace_000001.etl DUMP=TXT.

The Event Viewer Alternative: A Different Perspective

Prefer the familiar comfort of Event Viewer? You can use it for UE-V logging too! (Specific instructions for configuring Event Viewer logging for UE-V are not included in the provided source material, so consult official Microsoft documentation for detailed steps.)

Tips for Success: Making the Most of Your Logs

  • Be Specific: The more specific you are about recreating the issue, the easier it will be to identify the problem in the logs.
  • Two is Better Than One: When troubleshooting replication issues, run traces on at least two machines to compare and contrast the results. This can help pinpoint where the breakdown is occurring.
  • Don’t Be Afraid to Experiment: Experiment with different tracing scenarios and settings to get a better understanding of how UE-V behaves in your environment.

Conclusion: Unlocking the Power of UE-V

Debug logging is a powerful tool for troubleshooting UE-V issues. By understanding how to use it effectively, you can quickly pinpoint problems and restore harmony to your user experience. Don’t let those pesky setting gremlins get the better of you – take control with debug logging!
