Network Loading Slow on Boot

The last 2 days Ive noticed the network icon in the tray is slow to load. Ive also noticed that there is some type of cmd prompt or window that runs at boot, but it opens and closes so fast I cant tell what it is. Ive tried reinstalling all drivers to no avail. I have cleaned out MSConfig of junk that doesnt need to start.

I do have a SSD as my main drive and it still takes about 30-60 seconds to load.

Any idea how I can track down what services may be holding things up?

 

Win 7 x64 Pro

Doesnt appear to happen in safe mode.

 

So far I have disabled everything except essentials and it still happens. I have removed the GPU drivers for the GTX770 and it appears to be much faster. Im wondering if NVIDIA released a bad update.

 

I went through event logs and found a few interesting things and in order of occurrence:

DCOM got error "1084" attempting to start the service ShellHWDetection with arguments "" in order to run the server:
{DD522ACC-F821-461A-A407-50B198B896DC}

DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server:

DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server:

WLAN Extensibility Module has failed to start.
Module Path: C:\Windows\System32\IWMSSvc.dll
Error Code: 21

The Computer Browser service depends on the Server service which failed to start because of the following error:
The dependency service or group failed to start.

 

I found that the WLAN Module was caused by the Intel Pro wireless software. I removed that and only installed the driver which removed the WLAN Module failed to start error.

I also found that the Windows Driver Foundation service was set to manual and never started. After setting that to automatic everything appears to be functioning better.

I also did uninstall recent Windows updates from 4/9/14 to rule those out.

 

It seems to be a real crap shoot. Sometimes it reboots fine. Other times it reboots and gives the welcome screen and then a black screen for about 10-15 seconds and then loads the user profile.

Im still getting the The driver \Driver\WUDFRd failed to load for the device USB\VID_147E&PID_1002\6&5c5d692&0&3. error. The only USB device I have is for a mouse.

 

I have narrowed down the issue:

In my logs I have The driver \Driver\WUDFRd failed to load for the device USB\VID_147E&PID_1002\6&5c5d692&0&3. and it appears to happen after installed Intel HD4600 GPU drivers.

That error is directly related to this in the logs: Custom dynamic link libraries are being loaded for every application. The system administrator should review the list of libraries to ensure they are related to trusted applications.

There is a registry key that is calling a specific NVIDIA .DLL that is causing this error.
