Fix for Slow Boot up after installation of Dotnet Framework 4

Early this morning after I install dotNet Framework 4. My PC Start to boot very slow. So I search the internet for solution and luckily i found it.

Slowdown will happen if you have the following:

- Windows XP SP3
- installed .NET Framework 4

Here is what I found to fix the problem:

Solution A

1) Run cmd.exe from Start > Run
2) Type cd\
3) Type cd C:\Windows\Microsoft.NET\Framework\v4.0.30319\
4) Type NGEN executequeueditems and press Enter
5) It will take about 10minutes depending upon system speed. After the process is complete, the following prompt will appear in the command prompt C:\Windows\Microsoft.NET\Framework\v4.0.30319\
6) Type exit to close the command prompt.

After performing these steps, your computer will boot up at usual speed.
