Thanks again for all the information, it looks that they both have strongpoints and flaws. Iāv installed ewf, maybe I will try FBWF some other time. I really learnd a lot from it. 
All Comodo has to do is code a warning message when trying to enable this feature. Users who know they still want it can opt. in. Users who are not sure would follow the warning that their system does not have enough RAM to support this or they are into gaming and should not enable this feature.
