Does ReactOS have the same security problems as Microsoft(R) Windows(R)?
Microsoft(R) Windows(R) NT and successors aren’t really inherently insecure systems. We believe that Microsoft made a secure system insecure as a result of some poor decisions. For example, Windows XP gives every user Administrator rights by default. Some services are poorly implemented and ease of use often takes priority over security. We can, however, rearrange these priorities in ReactOS. What will be problematic is that Microsoft hasn’t pressured software creators to let their products run with normal user rights.
