If you need to increase the scratch space, the max in 64 bit is 1024 (undocumented by MS).

1 Mount the image

2 Load the winpe system hive - name it SYS and add this:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYS\ControlSet001\services\FBWF]
"WinPECacheThreshold"=dword:00000400

3 Unload SYS hive

4 Commit and unmount the image.

In the unlikely event you need more space, you can use imdisk to create a ramdrive. Imdisk is already included in my boot media
