PowerShell says “execution of scripts is disabled on this system.”

You can bypass this policy by adding -ExecutionPolicy ByPass when running PowerShell

powershell -ExecutionPolicy ByPass -File script.ps1

For Windows 7, Windows 8, Windows Server 2008 R2 or Windows Server 2012, run the following commands as Administrator:
x86 (32 bit)
Open C:\Windows\SysWOW64\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned
x64 (64 bit)
Open C:\Windows\system32\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned
You can check mode using

• In CMD: echo %PROCESSOR_ARCHITECTURE%
• In Powershell: [Environment]::Is64BitProcess
