Bad Windows Update

Today I downloaded 10 important updates, and when I restarted the machine became extremely slow. why is this happening?

 

It happens sometimes. I have even seen updates for updates in the past. That being said I haven't had any slowdown with the latest updates. So far so good on my end.

 

It could be due to .NET getting updated. Usually after the update assemblies need to be recompiled.

 

Yes I am highly suspicious of .Net update I have seen.

 

If you open task manager and see a process with the name mscorsvw.exe that is probably the issue.

You have two options:

1. Let the computer stay idle for around 15-40 min depending on your machine specs. (Higher will be faster)

2. You can force the JIT compile process with the following command by opening a elevated command prompt and add the following:

.NET version 4

Code:

c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\ngen.exe executequeueditems

for .NET versions 2.0 to 3.5

Code:

c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ngen.exe executequeueditems

HTH

 

Yes, I always have this after .net updates, mscorsvw.exe takes 100% of 1 CPU for quite a while.
