Two instances of mscorsvw after fresh install windows 7

BryanS · Sep 11, 2010

Not sure why but it seems these two instances aren't doing what they are supposed to do considering it never ate my cpu up while compiling after installing all major updates. (fresh install) Both have been in the processes for hours now.

have a few failed updates too which might be related? Hope to get this sorted.

These are due to upgrades (or first initialization) of the .NET Framework. Upon the first reboot (or install), this optimization will run only once and should take about 5 or 10 minutes (assuming a relatively modern PC). They run as low priority processes so they should not tax your PC and once they're done that one time, they shouldn't show up again unless you upgrade the .NET Framework to a newer version.

If however these keep going and going and never disappear, let us know.

Okay well the two instances of it have been there for 3 hours now, both at 0% usage. I know why they deploy and what they do already seems maybe my .net framework might have been incorrectly installed or something along those lines. I will follow any steps to get this fixed. They aren't slowing me down or anything but they shouldn't be there.

letting my computer go idle and restarting did not make the processes go away either might i add.

I think this site explains it very well: What is mscorsvw.exe and why is it eating up my CPU? What is this new CLR Optimization Service? - David Notario's WebLog - Site Home - MSDN Blogs
Essentially, just run "ngen.exe executequeueditems" and it should get these two processes to do their work and go away as they should.

It's not eating up my cpu i already read that guide prior to posting here it did not help me.
Tried that ngen.exe executequeueditems did not do anything, says it's not recognized as an internal or external command operable program or batch file

I just found an extra part in another article: Native Image Generator (Ngen.exe)

Essentially, you have to bring up an elevated command prompt and first navigate to the path C:\Windows\Microsoft.NET\Framework\v2.0.50727 or whichever version you have installed. Other common versions are v3.0, v3.5, and v4.0.30319. You would replace the version with whichever version you most recently installed. Once you've navigated to the path, run the ngen.exe executequeueditems and see if it works or not.

If not, note the error you receive. Additionally, have you tried restarting your PC to see if it gets these processes going (sounds inane but Windows can be weird sometimes).

I tried restarting my pc once more and then i tried what you said i think..

here i have included folder of framework its contents and the cmd prompt failing haha hope it helps.

Darician · Sep 11, 2010

When in the command prompt, first you have to type the command (without quotes) "cd C:\Windows\Microsoft.NET\Framework\v4.0.30319". After that, type in the "ngen.exe executequeueditems" and let me know what happens.

EDIT: Additionally, by elevated command prompt, I mean you need to bring up command prompt as administrator (right-click on it and click on "Run as Administrator" from the Start Menu).

BryanS · Sep 11, 2010

None of those worked... :eek:

Darician · Sep 11, 2010

Really? What results did you get out of it? A screenshot of the command prompt would be useful in this case so I can see what happens when you attempt these commands. I tried them and they seem to work.

EDIT: If this is recent, you may want to attempt to a System Restore to a point in time before this occurred and then try the updates again to see if the problem relapses or not.

Such an annoyance! On my last windows 7 comp this stuff never happened, and when mscorsvw DID popup it compiled perfectly under 10 minutes. Anyways here. Not good at this computer stuff obviously.. also, this is a fresh install just installed today (all of windows 7 on this computer its brand new). I can't exactly do a restore all my updates are installed correctly now as far as i know.

Darician · Sep 11, 2010

You have to type "cd C:\Windows\Microsoft.NET\Framework\v4.0.30319". You forgot the "cd" which stands for Change Directory in this case.

BryanS · Sep 11, 2010

Got it i pressed enter it went down a line reading C:\Windows\Microsoft.NET\Framework\v4.0.30319>

Now what? Appreciate the patience

Darician · Sep 11, 2010

Not a problem. Now that you have that, type in "ngen.exe executequeueditems". Let me know what result you get out of that.

BryanS · Sep 11, 2010

It did a buncha stuff and stopped aha scares the living sh!t out of me :shock:

oh nvm its still going

Darician · Sep 11, 2010

Well, keep an eye on it and let's see what happens. I know it generally takes 5 to 10 minutes to fully execute and sometimes a bit longer than that depending on the speed of the machine.

BryanS · Sep 11, 2010

Okay well it went through and finished with the original line. Does that mean it's finished?

Darician · Sep 11, 2010

Most likely it does. If it's finished, it should be sitting at a line with a blinking cursor showing C:\Windows\Microsoft.NET\Framework\v4.0.30319>. If this is the case, see if the processes are still present or not.

BryanS · Sep 11, 2010

Processes are still there for some reason. While i was watching it go through i saw a bunch of 'could not find' and other error related things so that is probably why. Is there a way to remove and re-install this whole framework thing manually? It's 4:35 am and i need sleep. If anyone has any ideas please feel free to share them as i will appreciate it. Def appreciate the help so far darician

Checking back in the morning sleep for now. Everything on my pc works fine btw enjoying it so far other than those 2 dreaded processes that hate me right now. Tired rambling ~

Darician · Sep 11, 2010

You should be able to go to the Control Panel and then Programs and Features and it should be listed there. If not, click on "View Installed Updates" while in Programs and Features and it should be listed there. Probably .NET 4.0 installed in your case. Let us know in the morning what you find.
