RGUber

This purpose of this VBScript is to process and organize data in RGU/REG files to remove duplicates, identify faulty entries, and move entries to ascending alphabetical order (the same way it is displayed in a registry editor).

Requirements:
Windows Scripting Host (included in most versions of windows)

rgucomp.exe and cereg400.dll located somewhere in your path (same folder as the script probably won't work if the script is run from another folder)

.reg and .rgu files are expected to be UTF-16LE with BOM

Usage:
Drag a .rgu, .reg, or .hv onto RGUber.vbs OR run "wscript.exe RGUber.vbs example.rgu"

Details:
When an rgu|reg file is specified, RGUber will:
1) create backup of input file
2) rename input file to boot.rgu
3) use rgucomp to convert it to *.hv
4) use rgucomp to convert new .hv to original rgu path\name
5) Reorder all keys in ascending alphabetical order and all values for each key in ascending alphabetical order with default value first

When an hv file is specified, RGUber will:
1) use rgucomp to convert it to *.rgu
2) Reorder all keys in ascending alphabetical order and all values for each key in ascending alphabetical order with default value first

Options
Open RGUber.vbs in your favorite text editor. All options are set at the beginning with (hopefully) meaningful descriptions.

Code:
'//Path to rgucomp (leave this as default if rgucomp.exe is located in your system path)
Const RGUCOMP = "rgucomp.exe"

'//Path to notepad, only needed if %OPENAFTER% is true
Const NOTEPAD = "notepad.exe"

'//The following options can be set to True/False or 0/1

'//Organize registry entries in ascending alphabetical order
Const REORDER = True

'//Open in %NOTEPAD% after conversion is done
Const OPENAFTER = False

'//Save any errors from rgu -> hv conversion
Const LOGERRORS = True

'//Save a backup copy of %INPUTRGU% as "%INPUTRGU%_Backup.rgu"
Const BACKUPRGU = True

Other info
If target file already exists, RGUber will ask if you want to overwrite.
Text files (the MS way) typically contain CRLF for next line. Output from rgucomp.exe contains many CRCRLF. RGUber removes the extra CR.
I have very few comments in the code. If requested, I will upload another copy with as many detailed comments as I can manage.
I tried to code this as efficiently as VBScript can possibly be. I kept getting errors when trying to run 'rgucomp.exe -b -nologo' so instead of running it directly, RGUber creates a bat file, executes it, then deletes it.
On my AMD Phenom 9600 with Vista64 and 3 SATA in Raid5, RGUber completes rgu->hv->rgu of 2084 lines in <3s
RGUber always saves output from rgu->hv conversion but deletes the file if there were no errors.
rgucomp.exe adds [HKEY_LOCAL_MACHINE\System\ObjectStore\RegistryUpda te] when it compiles an hv so this key gets added to the output of every conversion. I find it annoying so the next version of RGUber will probably remove it.
