I have created over 100 users using the wrong regional settings, therefore wrong date format. I wish to correct this without logging in as every user and going through the necessary steps.
I am looking for a way to do this in one go either via UI or via Powershell script.
Ideally I want a script that will ForEach the local users and run a command to change their language/regional settings.
NOTE: I am not using Active Directory therefore cannot use group policies.
Set your desired settings in one of the users, then Get those settings from
"HKEY_CURRENT_USER\Control Panel\International"
find the SID of each user then
Apply it to each user on:
"HKEY_USERS\[UserSID]\Control Panel\International"
To get The SID of the user you can use this Function:
Function GetSIDfromSAM()
{
Param(
[Parameter(mandatory=$true)]$userName
)
$myacct = Get-WmiObject Win32_UserAccount -filter "Name='$userName'"
return $myacct.sid
}
GetSIDfromSAM localuser
S-1-5-21-1837353773-20556466214-3321741005-1005
Then use the Foreach section (just for example)
New-PSDrive HKU Registry HKEY_USERS
Foreach ($SID in $SIDs)
{
Set-ItemProperty -Path "HKU:\$SID\Control Panel\International" -Name "LocaleName" -Value "en-us"
}
Of course you should update all the properties, you can use a switch section with all properties and values, or other methods, let me know if you need more help on this

I know how to set group policy to add a logon script to every user using GUI but I wanted to know how can this be done using Powershell commands(or maybe with python).
Currently, the only real way to set a GPO setting via powershell requires that you know the registry key you're changing (all GPO settings resolve to registry entries), but be aware that settings done like this won't show up with the nice descriptions in the group policy gui tools:
Get-GPO -Name 'Logon Scripts' | Set-GPRegistryValue -Context User -Key 'HKEY_CURRENT_USER\path\to\key' -Value 'Foo.bat'
Generally, the better way to do what you want is to set the AD User's ScriptPath property instead:
Get-ADUser $user | Set-ADUser -ScriptPath 'Foo.bat'
I am currently building a Hyper-V lab consisting of a DC and multiple networked VMs, using Windows Server 2016. I'd like to completely disable the windows firewall for all existing and newly created VMs.
The best way that I've found to do this so far is via Group Policy for the Domain Profile. Then set Windows Firewall: Protect all network connections to disabled. What I would like to do is to have a way of scripting this out (using Powershell if possible).
I've found that by performing the above steps in the GUI, it creates a few entries in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsFirewall\DomainProfile
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Microsoft\WindowsFirewall\DomainProfile
In each of those entries, there is a property called EnableFirewall which is set to 0. So I tried creating all of this using Powershell like this:
New-Item -path "HKLM:\SOFTWARE\Policies\Microsoft" -name WindowsFirewall
New-Item -path "HKLM:\SOFTWARE\Policies\Microsoft\WindowsFirewall" -name DomainProfile
New-ItemProperty -path "HKLM:\SOFTWARE\Policies\Microsoft\WindowsFirewall\DomainProfile" -name EnableFirewall -value 0 -PropertyType DWord -Force
Unfortunately it doesn't seem to be working, so there must be something else that I'm missing.
Does anybody know how to completely disable the windows firewall for all networked machines using the command line in Windows Server 2016?
Setting up the Windows-Firewall for your domain-computers through computer-startup-script is not a great solution in my opinion.
You should definetly use Group Policy for this task.
GP does exactly what I want, I would just like a way of modifying GP using Powershell. I'm building a lab from scratch, and I'm looking to script as much of it as possible rather than using the gui.
I am not completely sure, what you are trying to achive.
You have created a lab now and I think you are trying to script a complete automatic built-up for future use. Is this correct?
If yes, then my solution is maybe what you are looking for:
Create a new GPO in your lab named "Firewall-Settings" for example.
Make all of your needed FireWall-Settings to the new GPO.
In Group Policy Editor open the main-node named „Group Policy Objects“. (important) Find the newly created GPO, right-click it and select "Backup":
Save the GPO-backup to a folder. (folder must exist)
The GPO is beeing saved and named like on the screenshot below (GUID):
That's it for the preparation. Now you maybe want to script the creation of the GPO with Powershell for future use and import the backup to obtain it's settings in a new environment:
New-GPO -Name "FireWall-Settings" | New-GPLink -Target "DC=mydomain,DC=local" # distinguishedName of Target-OU
Import-GPO -Path $PathtoGPOBackup -TargetName "FireWall-Settings" -BackupGpoName "FireWall-Settings"
The Script creates a GPO in the new environment with the name "FireWall-Settings" and links it to the target-OU.
After that you import the settings of the backup-GPO. All the domain-members in scope of the GPO will get the Windows-Firewall configured automatically.
Now the process is documented and fully automatic, if this is, what you are looking for.
Kind regards
open cmd prompt with elevated mode and run this:
netsh -r ComputerName -u Username -p Password -c advfirewall set allprofiles state off
If you want to do it for all the machines. Get all the ad computers using get-adcomputer. Run a foreach loop and put the variable istead of computername.
If you have the domain admin creds, then you are good to go with this.
Hope it helps.
Depending on the profile you want to disable, specify profiles (public, domain, private) using the -Name parameter. To disable all profiles for a networked machine, where $computerName array is the hostname of your DC, PC etc:
$computerName = 'DC1, PC1, MS1'
Invoke-Command -Computername $computerName -ScriptBlock {
Set-NetFirewallProfile -Name Domain, Public, Private -Enabled False
}
Is there a way to create group of users with group policy apllied to them via Powershell/CMD?
My machine is not joined to a domain.
I want to prepare a script which I will use multiple times on other local computers/ machines to recreate group policy.
I want e.g restrict user access to Control Panel, Internet Access and stuff like that.
Thanks from advance for answers
For computers not joined to the domain, you can't use Group Policy. You will need to use Local Policy. Many of the items that you are looking for will simply be registry value that you can easily set with a PowerShell script. For example the policy for Hiding Fast User Switching toggles can be toggled like this:
Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" -Name HideFastUserSwitching -Value 0
You can look up where the values are by reading the .admx templates
Alternatively you could use David Wyatt's PowerShell module to read and modify policy files.
Finally the last option would be create the policy on one computer and then overwrite the .pol files on all the computers and then gpupdate /force. This of course could be scripted with PowerShell.
Copy-Item \\ExampleComputer1\C$\Windows\System32\GroupPolicy\Machine\Registry.pol \\ExampleComputer2\C$\Windows\System32\GroupPolicy\Machine\Registry.pol -Force
Copy-Item \\ExampleComputer1\C$\Windows\System32\GroupPolicy\User\Registry.pol \\ExampleComputer2\C$\Windows\System32\GroupPolicy\User\Registry.pol -Force
Security Templates would have to be exported from the Security Templates mmc snapin and then imported on the other computers with secedit
secedit /configure /db %temp%\temp.sdb /cfg yourcreated.inf
Using that solution --> Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" -Name HideFastUserSwitching -Value 0
Doesn't work.
I mean e.g:
Set-ItemProperty -Path "HKLM:Software\Microsoft\Windows\CurrentVersion\Policies\NonEnum" -Name NoRecycleBinIcon -Value 1
.admx template.
It should make my desktop recyclebin gone. This is just an example other settings also stays unchanged.
I want to access this path Computer Configuration\Policies\Windows Settings\Security Settings\Account Policies\Password Policy\Maximum password age in local group policy editor and modify its value through powershell script. I have tried to import module group (Get-Command -Module group*) but no methods/module is found.I have tried the following way in powershell and it didn't work.
Set-ItemProperty -Path \Computer Configuration\Windows Settings\Security Settings\Account Policies\Password Policy -Name Maximum password age -Value 20
Can someone help me in modifying the value through powershell scripting.
I am new to powershell scripting,so please ignore if any wrong info is
provided.
You can find it in windows registry, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters
MaximumPasswordAge REG_DWORD
You can get/set Registry values, somewhat counter-intuitively with the [get/set]-itemproperty commands.
Example:
Get-ItemProperty HKLM:\SOFTWARE\Policies\Microsoft\Windows\WinRM\Service\ -Name AllowCredSSP
However, this likely won't reflect in the Local Group Policy Editor interface.
Look up LGPO.exe, documentation is scarce, but it seems to work:
https://blogs.technet.microsoft.com/secguide/2016/01/21/lgpo-exe-local-group-policy-object-utility-v1-0/
(Current download is in the "Security Compliance Toolkit")
https://www.microsoft.com/en-us/download/details.aspx?id=55319
For parameters like max password age, I think best way is to use net.exe commant. Try to execute
net.exe accounts /?
For more complicated group policies in computer without domain, you can prepare policies in one computer, export it to file, and inport in other computers, by using secedit.exe
Try to google secedit /export, secedit /import usage
You can call secedit from powershell without any problems
I know that I can set a runonce key in the Win7 registry globally, which will be executed no matter which user logs on the next time, using this registry key:
HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
I need to do an initialization only for a specific user, so I wonder if there is a way to programatically (using Powershell) set a runonce-entry that is only executed if one specific user logs on, also if this user is not an Administrator.
Do you know of a way to do this? Thanks.
I think this question and the other (http://stackoverflow.com/questions/10908727/how-can-i-programatically-find-a-users-hkey-users-registry-key-using-powershell) are related:
Anyways, here is how you do it:
$User = New-Object System.Security.Principal.NTAccount($env:UserName)
$sid = $User.Translate([System.Security.Principal.SecurityIdentifier]).value
New-PSDrive HKU Registry HKEY_USERS
Get-Item "HKU:\${sid}"
Set-ItemProperty -Path "HKU:\${sid}\Software\Microsoft\Windows\CurrentVersion\RunOnce" -Name Command -Value "notepad.exe"
