SignUp Now!Confirm that this is a correct argument.To capture a trace of system behavior during a crash, you would typically use the Windows Performance Recorder (WPR.exe). However, because WPR.exe requires user interaction which might not be possible during or immediately after a crash, in this circumstance it would be better to start a trace automatically at system startup, or utilize a different tool designed for analyzing crashes, like LiveKD which takes a snapshot of live system memory, or a memory dump file.
To capture a trace using WPR.exe on startup:
First, create a startup entries.
1. Open Task Scheduler. Run `taskschd.msc` in the Run box (Win + R).
2. On the right-hand side, click "Create Basic Task".
3. Fill in a name and description for your task and click "Next".
4. Change the trigger to “When the computer starts" and click "Next".
5. Change the action to “Start a program” and click "Next".
6. Browse to the location of WPR.exe (usually `C:\Windows\System32\`), and then in “Add arguments” enter `-start GeneralProfile -filemode && timeout -1 && wpr -stop Desktop\trace.etl`.
After the system restarts the next time, it will begin an automatic trace when it boots up that will only stop and save when user manually presses any key, ideally after a crash has occurred. If system becomes too unresponsive after a crash, hard restart the system and the trace will be saved in `C:\Desktop` by the name `trace.etl`.
Remember that, larger the trace file, more detailed analysis we can get. However, a large file takes longer to analyze.
In any case, please take all necessary precautions before trying these technical fixes, and keep back ups of your important files. As always, apply these fixes at your own risk.
It's quite possible that you won't see `wpr.exe` running in Task Manager after a reboot. `wpr.exe` is designed to be a fairly lightweight tool and is primarily an on-demand service for problem diagnosis. It doesn't run persistently in the background under normal circumstances.Confirm that this is a correct argument.

It doesn't run persistently in the background under normal circumstances.
Your command `-start GeneralProfile -filemode && timeout -1 && wpr -stop Desktop\trace.etl` is generally correct. It tells WPR to start a general trace recording to a file until timeout is terminated by pressing any key or a system crash, and then stop the recording and save to `Desktop\trace.etl`.
However, this statement has some timing issues in the Task Scheduler context. The Role of `&& timeout -1` is to pause the command execution until you hit the key following the `-start` command. However, if the system crashes before you manually stop it, wpr wouldn't be able to execute `-stop` argument to save the results.
So, considering the scenario you're dealing with (a crash), what you need is to start recording with WPR at system boot and stop the recording at the next boot. For this purpose, creating two separate tasks seems more practical.
Create a new task as follows using the Task Scheduler:
1. For the "Start up" task
- Arguments: `-start GeneralProfile -filemode`
- Trigger: At startup.
2. For the "Shut down" task
- Arguments: ` -stop Desktop\trace.etl`
- Trigger: At an event (Log=System, Source=Kernel-Power, Event ID=109, which corresponds to a system shutdown).
Again, please ensure to backup important files and be aware that Microsoft encourages the use of these tools for advanced users or professionals because incorrect use can cause serious problems.

Thank you for providing detailed information about WPR command-line options. Based on this input, you can start and stop trace sessions depending on your needs:try again.
make one for the initial request while using this informationThank you for providing detailed information about WPR command-line options. Based on this input, you can start and stop trace sessions depending on your needs:
To start a trace session, you will use the start command.
Here's an example:
```
wpr -start GeneralProfile -filemode -recordtempto C:\Temp\
```
This command starts a trace with the GeneralProfile and records in file mode to a temporary directory C:\Temp.
If you want to use more than one profile, you can add another `-start` option:
```
wpr -start GeneralProfile -start CPU -filemode -recordtempto C:\Temp\
```
This command starts a trace using both the GeneralProfile and CPU profile.
To stop the trace session and save the trace file, you can use the stop command.
Here's an example:
```
wpr -stop C:\TraceResults\MyTrace.etl
```
This command stops the currently running trace and saves the recorded data to the file MyTrace.etl.
I hope this helps you navigate using the WPR command-line tool to address your issues. As always, remember to use these commands with caution, as improper use could lead to unexpected system behavior.

To start WPR automatically on startup and stop while crashing in the context of a BSOD, you'll want to save output to a location that persists after a crash. Writing directly to an ETL file is recommended as it will survive a system crash.
To automatically start your trace when the system boots, you'll want to configure a task in the Task Scheduler.
1. Open Task Scheduler (taskschd.msc).
2. On the right-hand side, click "Create Basic Task".
3. Enter a name and a description for your task, then click "Next".
4. Choose "When the computer starts" as trigger, then click "Next".
5. Choose "Start a program" as action, then click "Next".
6. Enter `C:\Windows\System32\wpr.exe` in the "Program/script" box.
7. In the "Add arguments" box, put your desired WPR flags. For a general trace, relayed to a file, you would use: `-start GeneralProfile -filemode -recordtempto C:\Temp\`
8. Click "Next", then "Finish".
The `"-recordtempto C:\Temp\"` argument tells WPR to write the trace to the `C:\Temp\` directory. Please replace with your preferred directory.
On reboot, your machine will automatically start recording a trace. Beware that traces can be large depending on the system load and the duration of the trace.
Unfortunately, WPR cannot be pre-configured to stop on a system crash such as a BSOD, because by that point, a large portion of the system services WPR relies on will have been terminated. However, as you're recording using `-filemode`, the ETL file is being written in real time and not held in memory hence you should have all the trace data leading up to BSOD.
Please test everything out and let us know how it goes, or if you have any questions or run into issues. Be aware that tracing may affect system performance, and traces can take up significant disk space.

I apologize for the confusion. The error message is indicating that WPR is having trouble with the path you provided to store the trace file.
The option `-recordtempto` only accepts directories, not a specific filename. It seems you're trying to specify the file name (`test.edl`) along with the directory, which is why it's giving you an error.
Try the corrected command:
```
wpr.exe -start GeneralProfile -filemode -recordtempto C:\Users\sonojo\Desktop\
```
In this case, WPR will save the trace file to `C:\Users\sonojo\Desktop\` and will automatically generate an appropriate filename.
After you stops the capture, you can rename the generated .etl file to `test.etl`. Please note that the correct extension for WPR files is .etl,
Your command will initiate WPR to start recording and save the trace file to the specified directory. The `-filemode` option writes the trace directly to the disk, making it more likely to have some data saved in the case of a system crash. However, it's important to note that if your system crashes (suffers a BSOD), the recording might stop immediately without finalizing the trace file reports properly. You might risk having an incomplete trace file.Will this work to auto save when system crashes?
wpr.exe -start GeneralProfile -filemode -recordtempto C:\Users\sobonojo\Desktop

However, it's important to note that if your system crashes (suffers a BSOD), the recording might stop immediately without finalizing the trace file reports properly. You might risk having an incomplete trace file.
Here’s how WPR works:
1. When it starts, it begins recording events in a circular buffer in memory or directly to a file (with the `-filemode` option).
2. When you stop the trace, it finalizes the reports and generates a trace file, writing either the entire contents of the circular buffer (for memory mode) or the data kept since it started (for file mode).
In simplicity, unless you have periodic triggers to stop and start new sessions to generate sequences of completed trace files, there's a chance that a trace started at boot will not provide useful information from a system crash, because the system crashed before instructions to stop the trace and hence finalize the trace file could be executed.
I would still suggest performing this action as sometimes, valuable data can be retrieved up until the point of the crash.
Great to hear that you could successfully create the trace file!It worked. however. how i make sense of the information and how to trace gpu
