MSCORSVW.EXE Hogging CPU resources? By Pete F Morgan

Your computer may suddenly start running slowly without you doing anything in particular. You would then try to check in your Task Manager and you'd find out that one file, mscorsvw.exe, is using up too much CPU resources. Now before you do anything with this file, its use must be known first. This is an executable file that optimizes your PC to make programs launch faster. This is most commonly seen when a program that you use will be using the ".NET" Framework in order for its program to start. It is a component of Windows and must not be removed from it.

In order for you to observe how this file is running, you can try to open the computer's Task Manager and then go to the Processes tab. It will be labelled as a ".NET Runtime Optimization Service." It can also be seen more than once inside the Task Manager but it will be part of its normal working process.

It usually runs when the PC gets any Windows Updates. Often times, Windows Updates will only get downloaded and will run during the day. During this time, it would start running as well and it may cause the computer to slow down.

"Mscorsvw.exe's" CPU usage can sometimes be high, but this can be normal especially during moments when the PC is doing an update. High CPU resource usage may also be caused by the.NET Framework trying to access the Internet all the time. Its Internet access is necessary because it will try to check for any certificate that may be needed to keep the programs and applications running properly inside the computer. Turning them off can be possible but it may also pose a high risk to your PC.

With cases where it may slow down the computer, getting a free PC optimizer can be helpful in maintaining your PC's overall performance and straighten out the "mscorsvw.exe" high memory usage. Running an optimizer can then help in making sure that any program that needs this file can be run properly to quickly end the service and stop it from consuming more CPU usage.

There are a few things that you may get to see when you encounter an error that goes like:

*file* is missing
*file* was not found
The blue screen of death
An error in Windows Startup and registry
Two or more found in Task Manager and high CP usage

Since it uses the Internet, mscorsvw.exe network access will be involved. A virus can also possibly attack and affect your PC's performance. The file cannot be recommended to be stopped or removed since letting it run will be needed to keep a PC's security running. Letting it run will keep the digital signatures running for the programs that are installed in a PC.

Regularly checking the performance of this executable file is not necessary. It will run automatically and when it has finished its task it will turn off on its own. There are some scripts that can be run inside a computer to be able to get most of the programs run faster and get it to end faster as well. These scripts work by letting the command run through the computer's other CPU cores. The normal case for it to run is to use only one CPU core of a computer.

In case that installing and adding the file is manually is needed, there are a few steps that can be done to have this corrected:

Use either your system setup CD, or use another PC that is running the same setup as yours to copy it from.
Look for the folder "C:WindowsSystem32Microsoft.NETFrameworkv2.0.50727" and save the copy there.
Open your PC's command prompt and type in "regsvr 32 *filename*" and then press Enter.

Malware and viruses can affect the performance of the.NET Framework altogether. To prevent an error from happening, you can:

Keep your.NET Runtime Optimization Service up-to-date.
Try to check for any invalid registry keys.
Try to regularly run an anti-malware scan in your computer.

Being able to download a helpful tool can help in immediately fixing this issue. This may also help when a computer encounters that dreaded BSOD. Windows XP in particular may get an issue most often since most of the programs that runs in this operating system version will require a.NET Framework before it can run properly, but Windows 7 may not encounter this very often.
