On my Win7 pro machine, I find two copies of the program. WmiPrvSE.exe from c:/Windows/System32/wbem WmiPrvSE.exe *32 from c:/Windows/SysWOW64/wbem I had to hard kill the computer with the power button as it would not completely close down the normal way. Since I have restarted the machine, it seems to be running normally with these processes without hogging the machine. When it was running badly, it had all 8 threads ties up and my memory usage was almost 8Gbytes. Now my memory usage is only 2.5Gbytes.

Best practices for resolving WmiPrvSE issues

A clean and tidy computer is the key requirement for avoiding problems with WmiPrvSE. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the WmiPrvSE.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
