We do this because we only want to enable User Stack Tracing against just the WMI service and not every svchost process. Note: It is important that you go back and reverse what you did in step 7 and modify path back to original after you are no longer needing the service to be broken out and uniquely named as failure to do this can prevent future WMI hotfixes from being installed.
Restart wmi service with net stop winmgmt and net start winmgmt commands again. Verify you now see wmisvchost. For sake of brevity here, follow steps from Scenario 1a with the exception of typing in wmisvchost. Here we want to use procdump to dump the wmisvchost. Reference steps listed in Scenario 1a above. First command will dump wmisvchost. Once it has completed, and then run second command to dump out each instance of wmiprvse. Command for dumping wmisvchost. At this point you will now need to open a Support Incident Case with Microsoft to get the process dumps analyzed to determine cause of high memory usage.
Scenario 2a: High Memory Consumption by Wmiprvse. This scenario is a little bit different than being caused by Heap, as just dumps in of themselves normally do not tell the full story. In this type of case, we need to know what type of wmi activity is occurring and it becomes significantly harder and more involved to try and determine cause.
Alternatively you could run following wmic command from command prompt to get a list of loaded providers and their associated PID you could then match up to PID with instance of wmiprvse with high. When memory usage is high, use Procdump tool to dump out the wmiprvse. The above command will produce 3 dumps space out 5 minutes apart each in same directory you ran the procdump command from.
Collect a network trace for 2 minutes using Network Monitor. At this point you will now need to open a Support Incident Case with Microsoft for data analysis and most likely for more in depth troubleshooting and data collection methods.
NOTE : If you have already broken the WMI service out to run in its own general svchost process following directions at beginning of this article, then you can skip to step 5.
Here we want to use procdump to dump the svchost process housing the WMI Service along with every instance of wmiprvse. First command will dump svchost. You may have to restart the computer after you apply this hotfix. The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time DST bias.
Additionally, the dates and the times may change when you perform certain operations on the files. Important Windows 8 hotfixes and Windows Server hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
For example, software or commands could find information about the state of BitLocker drive encryption , view entries from the event log, or request data from installed applications that include a WMI provider. Microsoft has a list of included WMI providers on its website. This is a particularly useful feature for enterprises that centrally manage PCs, especially as information can be requested via scripts and shown in a standard way in administrative consoles.
However, even on a home PC, some software you have installed may request information about the system through the WMI interface. However, prolonged high CPU usage is a sign something is wrong. That other process is the problem. The errors may be caused by the same process ID number, or you may see multiple different process IDs causing errors. Click each error and see what the ClientProcessId is to find out.
You can now pin down a process that may be causing problems. Also, when a program closes and reopens, it will have a different process ID number. With this information in hand, you now know the process that may be causing problems.
However, this will break many different things on your PC. Use Google Fonts in Word. Use FaceTime on Android Signal vs. Customize the Taskbar in Windows What Is svchost. Best Smartwatches. Best Gaming Laptops. Best Smart Displays.
Best Home Security Systems. Best External Solid State Drives. Best Portable Chargers. Best Phone Chargers.
