USB Driver change by Windows 7 SP1 Update

[itatang]

I prepare the Windows 7 on USB drive and it work perfectly until I have update the OS from Windows Update to SP1.

I try to bypass the SP1 update by installing Windows 7 to a internal drive and update it to SP1. Afterwards, I create a WIM image for the internal drive. Using the WIM file, I create a USB drive again with WinToUSB and it works again.

I think that the driver for usb boot may be corrupted by the SP1.

Can we update the registry or repair the WinToUSB driver whenever the USB drive is destroyed by the update in the further avoiding to start the process of create USB drive from the starting again.
