I am trying to run a cmd file that calls a PowerShell script from cmd.exe, but I am getting this error:
Management_Install.ps1 cannot be loaded because the execution of scripts is disabled on this system.
I ran this command:
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
When I run Get-ExecutionPolicy from PowerShell, it returns Unrestricted.
Get-ExecutionPolicy
Output:

The system is Windows Server 2008 R2.
What am I doing wrong?
If you're using Windows Server 2008 R2 then there is an x64 and x86 version of PowerShell both of which have to have their execution policies set. Did you set the execution policy on both hosts?
As an Administrator, you can set the execution policy by typing this into your PowerShell window:
Set-ExecutionPolicy RemoteSigned
For more information, see Using the Set-ExecutionPolicy Cmdlet.
When you are done, you can set the policy back to its default value with:
Set-ExecutionPolicy Restricted
You may see an error:
Access to the registry key
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied.
To change the execution policy for the default (LocalMachine) scope,
start Windows PowerShell with the "Run as administrator" option.
To change the execution policy for the current user,
run "Set-ExecutionPolicy -Scope CurrentUser".
So you may need to run the command like this (as seen in comments):
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
You can bypass this policy for a single file by adding -ExecutionPolicy Bypass when running PowerShell
powershell -ExecutionPolicy Bypass -File script.ps1
I had a similar issue and noted that the default cmd on Windows Server 2012, was running the x64 one.
For Windows 11, Windows 10, 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

MSDN - Windows PowerShell execution policies
Windows - 32bit vs 64bit directory explanation
Most of the existing answers explain the How, but very few explain the Why. And before you go around executing code from strangers on the Internet, especially code that disables security measures, you should understand exactly what you're doing. So here's a little more detail on this problem.
From the TechNet About Execution Policies Page:
Windows PowerShell execution policies let you determine the conditions under which Windows PowerShell loads configuration files and runs scripts.
The benefits of which, as enumerated by PowerShell Basics - Execution Policy and Code Signing, are:
Control of Execution - Control the level of trust for executing scripts.
Command Highjack - Prevent injection of commands in my path.
Identity - Is the script created and signed by a developer I trust and/or a signed with a certificate from a Certificate Authority I trust.
Integrity - Scripts cannot be modified by malware or malicious user.
To check your current execution policy, you can run Get-ExecutionPolicy. But you're probably here because you want to change it.
To do so you'll run the Set-ExecutionPolicy cmdlet.
You'll have two major decisions to make when updating the execution policy.
Execution Policy Type:
Restricted† - No Script either local, remote or downloaded can be executed on the system.
AllSigned - All script that are ran require to be digitally signed.
RemoteSigned - All remote scripts (UNC) or downloaded need to be signed.
Unrestricted - No signature for any type of script is required.
Scope of new Change
LocalMachine† - The execution policy affects all users of the computer.
CurrentUser - The execution policy affects only the current user.
Process - The execution policy affects only the current Windows PowerShell process.
† = Default
For example: if you wanted to change the policy to RemoteSigned for just the CurrentUser, you'd run the following command:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Note: In order to change the Execution policy, you must be running PowerShell As Administrator.
If you are in regular mode and try to change the execution policy, you'll get the following error:
Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To change the execution policy for the default (LocalMachine) scope, start Windows PowerShell with the "Run as administrator" option.
If you want to tighten up the internal restrictions on your own scripts that have not been downloaded from the Internet (or at least don't contain the UNC metadata), you can force the policy to only run signed scripts. To sign your own scripts, you can follow the instructions on Scott Hanselman's article on Signing PowerShell Scripts.
Note: Most people are likely to get this error whenever they open PowerShell because the first thing PowerShell tries to do when it launches is execute your user profile script that sets up your environment however you like it.
The file is typically located in:
%UserProfile%\My Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1
You can find the exact location by running the PowerShell variable
$profile
If there's nothing that you care about in the profile, and don't want to fuss with your security settings, you can just delete it and PowerShell won't find anything that it cannot execute.
We can get the status of current ExecutionPolicy by the command below:
Get-ExecutionPolicy
By default it is Restricted. To allow the execution of PowerShell scripts we need to set this ExecutionPolicy either as Unrestricted or Bypass.
We can set the policy for Current User as Bypass by using any of the below PowerShell commands:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted -Force
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass -Force
Unrestricted policy loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the Internet, you are prompted for permission before it runs.
Whereas in Bypass policy, nothing is blocked and there are no warnings or prompts during script execution. Bypass ExecutionPolicy is more relaxed than Unrestricted.
Also running this command before the script also solves the issue:
Set-ExecutionPolicy Unrestricted
If you are in an environment where you are not an administrator, you can set the Execution Policy just for you (CurrentUser), and it will not require administrator.
You can set it to RemoteSigned:
Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "RemoteSigned"
or Unrestricted:
Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "Unrestricted"
You can read all about Getting and Setting Execution policy in the help entries:
Help Get-ExecutionPolicy -Full
Help Set-ExecutionPolicy -Full
In Windows 7:
Go to Start Menu and search for "Windows PowerShell ISE".
Right click the x86 version and choose "Run as administrator".
In the top part, paste Set-ExecutionPolicy RemoteSigned; run the script. Choose "Yes".
Repeat these steps for the 64-bit version of Powershell ISE too (the non x86 version).
I'm just clarifying the steps that #Chad Miller hinted at. Thanks Chad!
RemoteSigned: all scripts you created yourself will be run, and all scripts downloaded from the Internet will need to be signed by a trusted publisher.
OK, change the policy by simply typing:
Set-ExecutionPolicy RemoteSigned
I'm using Windows 10 and was unable to run any command. The only command that gave me some clues was this:
[x64]
Open C:\Windows\SysWOW64\cmd.exe [as administrator]
Run the command> powershell Set-ExecutionPolicy Unrestricted
But this didn't work. It was limited. Probably new security policies for Windows10. I had this error:
Set-ExecutionPolicy: Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of...
So I found another way (solution):
Open Run Command/Console (Win + R)
Type: gpedit.msc (Group Policy Editor)
Browse to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Powershell.
Enable "Turn on Script Execution"
Set the policy as needed. I set mine to "Allow all scripts".
Now open PowerShell and enjoy ;)
First, you need to open the PowerShell window and run this command.
set-ExecutionPolicy RemoteSigned -Scope CurrentUser
Then it will ask you to confirm. Type Y and press Enter.
When you run this command, you can see that your system has set all policies for the current user as remotely. It will take a few seconds to complete this process.
The image will be shown like below:
To check if the execution policy has set. Type:
Get-ExecutionPolicy
If it was set, the output would be like this:
Open a Windows PowerShell command window and run the below query to change ExecutionPolicy:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
If it asks for confirming changes, press Y and hit Enter.
You should run this command:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
Win + R and type copy paste command and press OK:
powershell Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "RemoteSigned"
And execute your script.
Then revert changes like:
powershell Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "AllSigned"
Open the command prompt in Windows.
If the problem is only with PowerShell, use the following command:
powershell Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "RemoteSigned"
Setting the execution policy is environment-specific. If you are trying to execute a script from the running x86 ISE you have to use the x86 PowerShell to set the execution policy. Likewise, if you are running the 64-bit ISE you have to set the policy with the 64-bit PowerShell.
you may try this and select "All" Option
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
Open Run Command/Console ( Win + R )
Type: gpedit. msc (Group Policy Editor)
Browse to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Powershell.
Enable "Turn on Script Execution"
Set the policy as needed. I set mine to "Allow all scripts".
Now run the run command what ever you are using.. Trust this the app will runs.. Enjoy :)
You can also bypass this by using the following command:
powershell Get-Content .\test.ps1 | Invoke-Expression
You can also read this article by Scott Sutherland that explains 15 different ways to bypass the PowerShell Set-ExecutionPolicy if you don't have administrator privileges:
15 Ways to Bypass the PowerShell Execution Policy
I have also faced a similar issue. Try this.
As I'm using Windows, I followed the steps as given below.
Open a command prompt as an administrator and then go to this path:
C:\Users\%username%\AppData\Roaming\npm\
Look for the file ng.ps1 in this folder (directory)
and then delete it (del ng.ps1).
You can also clear npm cache after this though it should work without this step as well.
If you have Git installed, just use Git Bash.
Set-ExecutionPolicy RemoteSigned
Executing this command in administrator mode in PowerShell will solve the problem.
In Window 10:
If you are not administrator, you can use this:
powershell Set-ExecutionPolicy -Scope CurrentUser
cmdlet Set-ExecutionPolicy at command pipeline position 1
Supply values for the following parameters:
ExecutionPolicy: `RemoteSigned`
It solved my problem like a charm!
In the PowerShell ISE editor I found running the following line first allowed scripts.
Set-ExecutionPolicy RemoteSigned -Scope Process
For Windows 11...
It is indeed very easy. Just open the settings application.
Navigate to Privacy and Security:
Click on For Developers and scroll to the bottom and find the PowerShell option under which check the checkbox stating "Change the execution policy ... remote scripts".
Open PowerShell as Administrator and run Set-ExecutionPolicy -Scope CurrentUser
Provide RemoteSigned and press Enter
Run Set-ExecutionPolicy -Scope CurrentUser
Provide Unrestricted and press Enter
Open PowerShell as a administrator. Run the following command
Set-ExecutionPolicy RemoteSigned
Type Y when asked!
In Windows 10, enable the option under the name: 'Install apps from any source, including loose files.'
It fixed the issue for me.
To fix this issue, we have to set the execution policy, so that the PowerShell script runs on the particular machine. Here is how:
Open PowerShell Console by selecting “Run as Administrator” and set the execution Policy with the command: Set-ExecutionPolicy RemoteSigned
Type “Y” when prompted to proceed

In PowerShell 2.0, the execution policy was set to disabled by default.
From then on, the PowerShell team has made a lot of improvements, and they are confident that users will not break things much while running scripts. So from PowerShell 4.0 onward, it is enabled by default.
In your case, type Set-ExecutionPolicy RemoteSigned from the PowerShell console and say yes.
When I run any script from a .ps1 file on my server I receive an error about the Set-ExcutionPolicy being successful but being overridden by a higher scope.
However none of the code I am running has anything to do with execution policies or changing them. Any Idea why I'm getting this error?
This is on a Windows 2012 R2 server where execution policy for all levels is set to remote signed. I'm running on PowerShell V4.0
If I open PowerShell or the ISE and type in the command it completes without showing the error it only occurs when I try and run a script from a .ps1 file.
This is the error:
Set-ExecutionPolicy : Windows PowerShell updated your execution policy
successfully, but the setting is overridden by a policy defined at a more
specific scope. Due to the override, your shell will retain its current
effective execution policy of RemoteSigned. Type "Get-ExecutionPolicy -List"
to view your execution policy settings. For more information please see
"Get-Help Set-ExecutionPolicy".

The "Run with PowerShell" context menu entry for .ps1 files invokes the following commandline:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & '%1'"
It's stored in the registry key HKCU\Microsoft.PowerShellScript.1\Shell\0\Command. Since you have the execution policy defined via Group Policy, setting a conflicting execution policy in the Process scope whenever you're running a PowerShell script via its context menu causes the error you observed.
Change the commandline in the registry to something like this:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -File "%L"
and the error will disappear.

I get above error in package manager console. I found some solution, but I cant fix it. I tried followings
PowerShell says "execution of scripts is disabled on this system."

I changed execution policy,
But I allways get the same error.
It's possible that you changed the execution policy for 64-bit powershell and the package manager is running 32-bit (or vice versa).
I'd try opening 32-bit console (PowerShell (x86)) and setting the execution policy there, as the error is definitely pointing to that kind of resolution.
Make sure you restart visual studio after changing execution policy so that changes can take effect. Also make sure you changed execution policy globally with administrator username and password.
We have been facing the same issue today with Visual Studio 2017 and Entity Framework 6, and none of the solutions proposed here has worked. As a workaround, this is the temporary solution we found to be able to use Entity Framework commands in the Package Manager Console:
Execute the following commands in the Package Manager Console
Set-ExecutionPolicy -Scope Process Bypass
Import-Module "your-solution-directory/packages/EntityFramework<your EF version>/EntityFramework.psd1"
Actually, the Import-Module command is what the init1.ps1 script does.
