It is rare that an update for Windows does not mess up something or the other and the latest Windows 10 update is no different. This time the problem is pretty annoying and has given quite a scare to many users.
This is how it unfolds. The Windows update KB3201845 update is installed and almost right away, Task Manager shows that you are using 90 or 100 percent of your disk space. Instantly makes you wonder what the heck is going on. Where did all of that free disk space go?
Blame the WPR
This error is caused by the Windows Performance Recorder, which is a program designed by Microsoft that records the performance of your system. Every time you boot up your PC, it starts recording activity and stores it on your disk drive in case you want to review this data and figure out the root cause, in case something goes wrong.
Unless you are a troubleshooting expert, it is unlikely that you will ever go through all this information, besides if you want to get rid of this 100% usage error, you have to go ahead and disable this tool.
Disabling the WPR
Once you disable the Windows Performance Recorder, it will stop recording and as a result, the disk usage of your PC will go back to normal.
The process of doing this is super easy and to begin with, we will open the command prompt with admin rights. you can do it in two ways:-
- Right click on the start button and select the option that says, Command Prompt (admin) from the menu.
- Click the start button and in the search panel on the right side, type in command prompt. Right click on the first result, which should say command prompt and select Run as administrator.
In case a User Account Control dialog box pops up then just click confirm.
Once the window is open, you simply need to input a single command- “WPR –cancel” (without the quotes). Right away your disk usage % should go down drastically and plenty of free disk space should be available.
The WPR starts up every time you start your computer and as a result, you will need to run this command every time you reboot. A bit of a pain but so far, Microsoft have not released any other fix for this.
If you get an error that says ‘There are no trace profiles running’ then it means that the WPR is not running and the disk usage problems are caused by something else.
