[REQ]-Script to change some Excel's registry entries

I need a change script to change some registry entries for M$ Excel program (solely 2010, 2013 and 2016), to make it work along with Sandboxie.
I can't do a fixed reg file since it has some variables that changes and become unique on every installation on every different scenario.


Requirements:
1. The script needs to make a backup (reg file) of the following entries as a first function (here don't matter Office version or achitecture):
HKEY_CLASSES_ROOT\Excel.Sheet.12\shell\Open
HKEY_CLASSES_ROOT\Excel.Sheet.8\shell\Open
HKEY_CLASSES_ROOT\Excel.SheetMacroEnabled.12\shell\Open


2. Then, the script must be able to make the following changes depicted in the image:

​

The image shows only Excel.Sheet.8 entry yet the script must consider Excel.Sheet.12 and Excel.SheetMacroEnabled.12 as well.




To all the scriptmasters in here, thanks in advance for you help

 

It's interesting how this entry looks in a reg file:

Original
[HKEY_CLASSES_ROOT\Excel.Sheet.8\shell\Open\command]
@=""C:\\Program Files (x86)\\Microsoft Office\\Office16\\EXCEL.EXE" /dde"
"command"=hex(7):7a,00,6e,00,3d,00,42,00,56,00,35,00,21,00,21,00,21,00,21,00,\
21,00,21,00,21,00,21,00,21,00,4d,00,4b,00,4b,00,53,00,6b,00,45,00,58,00,43,\
00,45,00,4c,00,46,00,69,00,6c,00,65,00,73,00,3e,00,3f,00,25,00,38,00,47,00,\
69,00,63,00,4b,00,63,00,76,00,39,00,6f,00,49,00,60,00,6b,00,77,00,24,00,3d,\
00,5b,00,55,00,5b,00,20,00,2f,00,64,00,64,00,65,00,00,00,00,00


Changed
[HKEY_CLASSES_ROOT\Excel.Sheet.8\shell\Open\command]
@=""C:\\Program Files (x86)\\Microsoft Office\\Office16\\EXCEL.EXE" \"%1""
"command"=hex(7):7a,00,6e,00,3d,00,42,00,56,00,35,00,21,00,21,00,21,00,21,00,\
21,00,21,00,21,00,21,00,21,00,4d,00,4b,00,4b,00,53,00,6b,00,45,00,58,00,43,\
00,45,00,4c,00,46,00,69,00,6c,00,65,00,73,00,3e,00,3f,00,25,00,38,00,47,00,\
69,00,63,00,4b,00,63,00,76,00,39,00,6f,00,49,00,60,00,6b,00,77,00,24,00,3d,\
00,5b,00,55,00,5b,00,20,00,22,00,25,00,31,00,22,00,00,00,00,00

However, on VMs I watch those hex numbers in blue to vary from installation to installation.
