Windows performance recorder

Technical Level : Intermediate

Windows performance recorder is a good tool to help us diagnose computer problems.  It is relatively easy to install and run and runs in win 7, 8, & 10


In order to diagnose your problem you will need to download and install the belowWe suggest you create a restore point before running the trace.  It is safe in the vast majority of situations but it cant hurt to have one.

To run WPR you need to:

Install the WPT (Windows Performance Toolkit) by downloading ADK from here

If you are running windows 10 you should use the newer version found here

There is no need to install anything but the windows performance toolkit.  That is  about 100Mb.  You do not need to install the entire ADK (or SDK)

1. Run ADKSetup.exe.
2. Click Install, specify the location where you want to install the Windows ADK features, and then click Next.
3. Select the Windows ADK features that you want to install (windows performance toolkit), and then click Install.

Help with installation (if needed) is here

When you have downloaded and installed it, open an elevated command prompt and type the following 

WPRUI.exe (which is the windows performance recorder) You should see this

Unless your problem involves sleep, shutdown, waking, or reboot check off the following boxes

There are various options.  Choose the one that applies to your situation

If you want to reduce the size of the file you can choose "Light" instead of verbose

Please run the trace when you are experiencing the problem

When you are ready or are experiencing the problem Click Start

Let it run for 30 secs  and save the file (it will show you where it is being saved and what the file is called)

It will generate a large file and the longer you run it the larger it will be ZIPPING the file reduce the size by a factor of 10 so a 10 Gig Etl=1 Gig zipped file  Please dont upload an ETL file that is larger that 4 Gb unzipped.  If your is bigger run a shorter trace

Zip the file and upload to us on Onedrive (or any file sharing service) and give us a link to it in your next post. It will be faster for you to upload and for us to download.  Be sure to upload the file that ends in "ETL" not the smaller folders that end in PDB!!!

If your problem involves sleep, hibernation, shutdown, or reboot you will need to configure WPR differently.  For example for a reboot issue configure it like this (this will reboot your computer as soon as you click start so close your work)

For shutdown issues configure it like this


There are some special situations where you need to configure WPR differently.  These are only necessary if they apply to you

To correctly capture event stacks on 64-bit systems that are running Windows® 7, disablepagingexecutive should be set to On, and the system must be rebooted before you start performance recording. For 32-bit systems that are running Windows 7 and for all systems that are running Windows 8, you can operate performance recording without setting disablepagingexecutive to On.  To do this type wpr -disablepagingexecutive <on/off> in an elevated command prompt

Sorry if I'm being dense here. But how long do I leave the trace running? What am I supposed to do with the trace once I have it? I see the instructions at the end, just don't understand them.


As it says in the wiki let it run for 30-60 seconds (it is a BIG file) and only needs to be run once.  Once you run the trace and save it you need to upload it to Onedrive (or any file sharing service) and put a link to it in your next post.

To ZigZag,

apologies for posting to the wiki, and I want to Create a Question like your email said...but where's my text?

Your email says:

Ask a question

Open the Ask a question page to start a thread in the Windows category. Your issue will appear in the Details field. Complete the remaining fields and click Submit.

But when I click on the link there is no text!  You mean I have to write the whole thing again?


And if you read your post back to Steve you say...put a link to it in your next post, which implies post back to this thread...

Apologies just one of those go do all the work to help MS solve a problem, they tell you we've put it somewhere else and loose it...




Do you mean this text?  All you need to do is to start a new thread and copy/paste this into it.  Feel free to put a link to the new thread so I can find it and help you there.

I like others am having issues with RunTime Broker and have completed 2 analyses as follows:

Small one (101 MB): Only CPU and Network I/O are measured

Bigger one (201 MB): as per second diagram above (but with Network I/O added), most options are measured.

My issues with RTB are:

  • 15% CPU constant
  • growing memory (RAM) to excess of 1GB
  • Network utilization of > 7.5Mbps Constant

I am on Win 10 (10240) MSDN ISO with all patches (to date) applied.

Note that I've zipped using 7z with ULTRA compression to reduce the size.

Hope you can sort this out as it really is a pain in the network.... :)

My dropbox link is as follows:

Thanks and best regards

Same here

Thank you for the article. After the Windows 10 Creators update our PC began taking over 6 minutes to boot or reboot. Here is a link to the WPR output file on One Drive:!All7UDwmxTD6babkjvefQNrLs7E

We've tried a lot of fixes, including the "turn hibernation off" command prompt suggested by another user. Nothing has helped yet.

Thank you for your help. Please let us know if you need any more information.
