Regsvr32.exe loads the CPU, what to do?

Microsoft Register Server

One of the unfortunate situations that can meet the user systems Windows 10, 8 and Windows 7 Microsoft Register Server (regsvr32.exe) that loads the processor that is visible in Task Manager.

While not always easy to discover what actually creates this load.

In this article I’ll tell you in detail about what to do if the regsvr32 process creates a large load in the OS (operating system) and how to detect what is the root cause of this and consider options for problem resolution.

Why do we need a Microsoft Register Server.

Microsoft Register Server

By itself the Register Server regsvr32.exe is system program Windows which registers some DLL libraries (system program modules) in the system and monitoring their removal.

This common system process may be included not only their own operating system (for example when installing updates) but also unauthorized applications and their modules for which you want to install your libraries in order to make it work.

In general as Windows itself and third party programs may be cause of startup Microsoft Register Server (regsvr32.exe).

Just remove the module regsvr32.exe from the system is impossible (as it is a required element of Windows) but you can easily find out what caused the problem and try to eliminate it.

How to reduce the load on the CPU caused by the process regsvr32.exe. Note: previously than be taken to the below steps try just restarting your computer or your laptop.

In addition to Windows 10 and Windows 8 take into account that you need to use restart and not shutdown and enable (as in this case the system will start not as after a reboot).

Likely this will be enough to correct the problem.

If the cause is not eliminated and in task Manager you see that regsvr32.exe CPU is still almost always the reason for that is some kind of program or component of Windows.

That included the Microsoft Register Server to perform actions with some DLL but the job hangs for some obscure reason.

The user always has the option to find which program caused the login server which the library freezes and fix the problem with their hands.

So here we go: First download Process Explorer (for Windows 7, 8 and Windows 10 (32 and 64 bit) ) only from the Microsoft website at the following address — https://technet.microsoft.com/ru EN us/sysinternals/processexplorer.aspx and install this software.

In the list of running processes in Process Explorer identify the process that creates the load on the CPU and open it — inside you’ll likely find the “begotten” process regsvr32.exe.

In this way we found out which program (the one inside which the process runs regsvr32.exe) resulted in a Register Server.

the process regsvr32.exe

If you zoom in and hold the mouse pointer over the process regsvr32.exe you will find the line “Command line” and the command that was given to this process (I haven’t the picture of this team but you perhaps it will be shown as regsvr32.exe with the team and the name of the DLL) which will be shown and a library that puts a lot of load on the processor.

Possessing this information you will easily be able to eliminate CPU load for yourself.

Another way.

If you are aware of the program that started the server registration you can make an attempt to complete this process (shooting process) and restart it again.

Can also help simple reinstallation of this application.

If it’s some non original (counterfeit) program — antivirus may block it so the antivirus can be temporarily disabled (it can block the check of the modified DLL in the system).

If the problem arose subsequently upgraded to Windows 10 and the program creates the process regsvr32.exe is some security software (antivirus scanner firewall) try to remove it restart the computer and start again.

If you do not understand what is this program try using the search on the Internet for the name of a DLL library which runs the script and find out what is this library and where it belongs.

For example if it is some driver try to manually uninstall and install this driver.

In some cases help can boot Windows in safe mode if the Register Server interfere with other programs.

In consequence of this boot into safe mode see what a large load on the CPU and do not reboot boot in normal mode.

Please note that regsvr32.exe in task Manager is usually a systemic process but in practice it can occur that the same name is running some sort of Trojan or virus.

If you have such concerns (for example the location of the file has a difference from the standard location C:\Windows\System32\ you can easily check the CrowdInspect program to scan running processes for the presence of Trojans and malware.

All good!
