Latest Powershell is 5.1 According to this site adsecurity.o rg/?p=2277 adsecurity. org/?p=2604 Powershell included with OS is of course 8-years old, outdated Do you guys recommending updating Powershell for better and maximum security, other than that I'm not a programmer/ developer or a powershell geek by the way. Also would it enable those security features by default or do I have to manually do it myself? I'm not familiar with Powershell except the fact that I know it can be excecuted in background silently, run commands. Also do I have to only download latest setup Is it cumulative .like .net Framework? or I'd have to download al (4.0, 5.0, 5.2l, then install one by one?
