Thank you very much for your informative answer.
It's a bit humorous situation. Actually I'm well aware of almost all the above mentioned methods and programs. Thank you for link to registry tweak I didn't know about them. I even can add to your list some programs like VoodooShield or NVT ERP, RollBack Rx or ToolWiz Time Freeze, Paragon (or Macrium) etc.
The thing is that I want to create setup as minimalistic as it possible. Just having EIS properly tweaked.
And the developer pushes me back to using me EIS in combos progs again.
OK, no problem. Really thank you very much for your help.
I'm happy with what I have in EIS now. Though I'll be twice happier if that feature in BB and FW to prevent alerts and disallow everything not allowed by the user in EIS/EAM will appear.
