The following table contains possible examples of cmd.exe being misused. Legal Copyright: Microsoft Corporation.Product Name: Microsoft Windows Operating System.For more information about running scripts and setting execution policy, see about_Execution_Policies at You cannot run this script on the current system. Status: The file C:\windows\SysWOW64\cmd.exe is not digitally signed.In theory, if you were running tons and tons of quick commands, like a script that runs thousands of little utilities that are relatively instant. The specific timings of a path search using %SystemRoot%, hardcoded, or both together.īut you're not going to be able to perceive it, either way. I'd definitely be interested in your findings if you tested this. Then fix the path so only one is in there - the OTHER one - and run that test again. Then fix the path so only one is in there, and run the test again. But in practice, we're talking millisecond.ĢB) You could perhaps run a timed check of a command that doesn't exist - mash your keyboard - and time how long it takes for the prompt to return. The performance gain should not be perceptible, but in theory, having it in there once will prevent it from searching the same folder twice for your executable.Though if Windows was 'smart', it probably decodes it only once and stores it in memory in its decoded format. Removing the %SystemRoot% one and leaving the hard-coded one in might be faster in that Windows is not having to decode the %SystemRoot% environment variable into its true value when you check your path. I don't know why someone would want to do that, but it's possible, and %SystemRoot% would always run in the right place. ![]()
