WinPE is cool but takes forever to boot, even off of a USB Flash Drive. Any suggestions on how to speed up the process. Also, Since I'm running it off of a 256 usb flash drive space is at a premium. What can I remove? Thanks!

What you can remove depends on what you need to begin with.,

Microsoft is supplying a list of files that can be safely removed in the next release of PE. Here is the list and the accompanying text explaines it.

Reducing the Size of Windows PE

The non-customized size of Windows PE is about 160 megabytes (MB). By removing non-essential files, you can reduce the 32-bit version of Windows PE to an on-disk image size of 86 MB.

Important

Removing files from Windows PE may cause your custom applications to fail.

easy way is to just not load networking support unless you need it. edit your STARTNET.CMD or just use regedit to make PE not use it in the firstplace and then if you need it maunally start it by typing it in the cmd window
