+## "scripts is disabled on this system" on Windows

+Based on [this issue](https://github.com/remy/nodemon/issues/1619), if you see the following on Windows:
+
+```
+PS> nodemon app.js
+nodemon : File C:\…\nodemon.ps1 cannot be loaded because running scripts is disabled on this system. For more

+FullyQualifiedErrorId : UnauthorizedAccess

+
+The solution is as follows by [Felipe Jacob](https://github.com/adelbs):
+
+It's a security restriction of the Windows PowerShell.
+
+1. Open up a powershell command window (open it as administrator)
+2. To check out current restrictions type "Get-ExecutionPolicy"
+3. Enable powershell by typing "Set-ExecutionPolicy remotesigned"
