The genuine wermgr.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation. "WerMgr.exe" should reside in "C:\Windows\System32". It is the Queue Management component of Windows Error Reporting (WER). "Wermgr.exe" alerts the user to error reports put in the reporting queue system as ".cab" files by "WerFault.exe", (or "WerFaultSecure.exe" if problems arose in a secure application), and asks the user for permission to send them to Microsoft's Watson backend servers. It also receives Microsoft responses with answers to earlier WER submissions. Settings exist to allow automatic submission of basic information about errors, although permission is still asked to send more detailed data. If conditions do not allow sending reports immediately, (e.g., no network connection), "WerMgr.exe" can set "triggers" for itself to restart later, (e.g., when network connection occurs). Enterprise administrators can set group policy to adjust WER behavior.
WERMgr stands for Windows Error Reporting Queue Manager
The .exe extension on a filename indicates an executable file. Executable files may, in some cases, harm your computer. Therefore, please read below to decide for yourself whether the wermgr.exe on your computer is a Trojan that you should remove, or whether it is a file belonging to the Windows operating system or to a trusted application.

Known file sizes on Windows 10/11/7 are 53,760 bytes (38% of all occurrences), 54,272 bytes and 37 more variants.
Wermgr.exe is a Windows core system file. The wermgr.exe file is a Microsoft signed file. The program is not visible.
Wermgr.exe is able to monitor applications.
Therefore the technical security rating is 2% dangerous, but you should also take into account the user reviews.
Uninstalling this variant:
The developer Microsoft provides a support site for assistance, and an uninstaller (Control Panel ⇒ Uninstall a Program ⇒ Microsoft Windows).
Is wermgr.exe a virus? No, it is not. The true wermgr.exe file is a safe Microsoft Windows system process, called "Windows Problem Reporting".
However, writers of malware programs, such as viruses, worms, and Trojans deliberately give their processes the same file name to escape detection. Viruses with the same file name are for example HEUR:Trojan-PSW.MSIL.Agent.gen (detected by Kaspersky), and ML.Attribute.HighConfidence (detected by Symantec).

windows error reprting manager. nothing harmful
When Microsoft really asses up its OSes, they have to write Error Managers to handle the multitude of constant errors produced by their OS. This is that process. Fortunately, like most of Microsofts applications, this one is totally unnecssary. Feel free to turn it off, it will stop trying to find out why your programs have crashed and will stop sending Microsoft bug reports. James
wermgr.exe causing 100% CPU on Vista. I've just disabled it in Administrative Tools- Services- Windows Error Reporting Service Ken
keeps coming up on my pc and I cant open any programes cant get rid of it pete
It is NOT digitally signed Shaggy
i have the same problem didn't solve it yet. jurrian lamm
I stopped the service and changed it to manual, then removed the error reporting task, but the Wermgr.exe kept running in Vista and using up to 50% of my CPU. I couldn't dlete it from the System32 folder. I rebooted to the Windows repair module and deleted the file. That solved the issue.
It is common system file in Windows 7 but I cannot find if in my Windows XP computer. Randy Bell
Virus scanner said it wanted to adaped some system settings Bram (further information)
I had multiple security services running making this problem. i deleted 2 of em and the problem went away
It is common system file in Windows 7 but not needed, as soon as I stopped it and quarantined it my laptop work fine, I had nothing but problems and errors before removing the offending file. Shazza
uses over 50% cpu on vista, stop services : windows error reporting, update and windows module installer
This process was 'terminated by Rkill or while it was running'. pochp
comes up with a message, click ok , goes away Muthu Pillay
had same problem - it started using ~50% of my processor load. After little research with ProcessExplorer, i found out that it is crashing because of Philips MediaServer that I installed few days ago. Uninstalling MediaServer fixed the problem. It had problems with MediaServer Crash reporting... but since it is a important part of windows then everyone should first try to figure out why it is acting like that, in most cases some other new application is casing problems because it has been build in wrong way :) Ergo
How to stop wermgr.exe file. Shailendra
Scanner designed to search and identify unidentified malware. Stephen Cohn
I have about 18 wermgr.exe apps running simultaneously, and as I try to end the processes they pop up again. My computer has ground to a halt. Turning the app off in Admin tools generates an error message, and tells me to contact my system administrator. I thought I WAS the system administrator. Bottom line, I cant turn it off.... GW
wermgr.exe causes trustedinstaller.exe to use all ofthe available memory causing the computer to blue screen and restart Bert van Raalte
Pointless and interfering process, which starts and restarts constantly when it decides it is going to flare up. Only changeable via Administrative Tools, worthwhile stopping it altogether as does nothing. Matt
Wermgr installed, or gained a lot more authority, with "update" KB3080149. Uninstall this update and all the excessive wermgr activity will stop. You will then have to hide the update so it wont install again. michael wolk
It's annoying, it keeps running in the background then the window I'm working in loses focus for a few seconds. Theo
It's eating Gigabytes of Bandwidth. It closes when there's no internet connection and relaunches when I'm busy looking else where. Naton
Uploading data, using all of my bandwidth. William East
it will try to collect the errors from "Windows Error Reporting" to be later send to the Microsoft teams by uploading the errors (not your personal files). They will then use the error listings from that upload to try to fix the cause (Hopefully). F.Andrew (further information)
Win 7 Pro - multiple wermgr.exe processes running in task manager. Takes up 30% of 16 GRAM, and 65% CPU on ASUS i7 3300. Robert.
When all net guard settings are switched on this program is the first in line to request internet access. Since I blocked it's access the problem I experienced has been greatly reduced. It seems to be responsible for downloading massive amounts of data to my computer for no apparent reason. It may be the same program responsible for mysteriously causing the take up of disc space on the hard drive. This slowly increases with time & even after all cleaning & maintenance tasks have been done the space taken up has mysteriously increased. I often have to reset to factory defaults to clear this used space, but the program is still there. After reboot it's often necessary to open a new account & delete the old one to get rid of further problems. The program however is still there & still continues to try & run. Mark Dyson
Windows 10 has reinstalled itself for the third time (in 8 months). Each time massive problems, the latest being wermgr.exe. We fixed the problem by installing Ubuntu. We have switched completely over & are now moving our customers over as well. James
Causes 100% disk use whenever it runs. Can run 10-20 minutes at a time making the computer mostly unusable. It didn't even run when a program crashed, it just runs upon waking from sleep mode on HP Envy 700-074 with Windows 8 64-bit. Chuck R.
This might be the popup that lets you close the app or wait for it to stop freezing when an app crashes/freezes
This software try to access internet without explanation what data from my PC they will grab. I blocked it using my firewall. Roger
I have it in 2 locations: C:\Windows\SysWOW64\wermgr.exe C:\Windows\System32\wermgr.exe Mary Thomas

Best practices for resolving wermgr issues
A clean and tidy computer is the key requirement for avoiding problems with wermgr. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the wermgr.exe process on your computer, the following programs have proven to be helpful: ASecurity 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. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
