Which scripts? Malicious scripts...yeah. But you can stop using wscript,mshta,bat,etc... and only allow powershell signed scripts with JEA restriction.

indeed, but the point was this malicious scripts usually try to install programs, like droppers.

Running and installing are different things. A popular dropper I frequently run into for example never drops an executable to disk, it loads base64 from registry, decodes/decrypts it and reflectively executes the .NET assembly which in turn decodes and executes shell code from registry.
