Allow Users on Domain to Control Power Settings

Wayne Zimmerman 2 Comments

In some domain environments you need to allow some control back to the users where they can manage it best. A perfect example of this is Power Settings, by default a normal domain user does not have the rights to control the power settings on the PC. This can lead to the computer turning off the monitor or going to standby at inopportune times. A way to solve this problem is by modifying the registry so any user authenticated / interactive user can modify these settings. To do this you need to use the regini.exe, it allows you to modify permissions in the registry from command line. Basically anything under registry key: (HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\) need to be given permissions to be modify by the user. Below I have included some code that needs to be placed in a text file for parameters to pass to regini.exe during workstation start up.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\GlobalPowerPolicy [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\0 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\1 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\2 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\3 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\4 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\PowerPolicies\5 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\ProcessorPolicies [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\ProcessorPolicies\0 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\ProcessorPolicies\1 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\ProcessorPolicies\2 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\ProcessorPolicies\3 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\ProcessorPolicies\4 [1 5 7 11 17 21]
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg\ProcessorPolicies\5 [1 5 7 11 17 21]

Once you have this file made save it Machine Startup Scripts directory for Group Policy. Then add the following entry to the Group Policy (shown below) and the users should now be able to modify their computers power settings.

List Local Accounts from Computers in Active Directory

Wayne Zimmerman Leave a comment

When you finally take the plunge and decided that the only way to take your business to the next level is to setup a true client/server environment, here is a script to help you clean up those old accounts. When you convert to an Active Directory structure, you need to remove all the old local user accounts. This will reduce the security risks by removing accounts that you can’t force to conform to the rules setup by Group Policy. Also, if you were running these users as Administrators or Power Users and now have limited them down to a Standard user, without removing their old local accounts they may have elevated rights that they don’t need. Using this script you can query every computer in you Active Directory and get a list in CSV that you can use to know where that accounts are that need to be removed. In this script you can modify the output file so you can save the file where you want. You will also need to modify the Active Directory information to match your Domain configuration.

Tip: You can remotely connect other computers on your domain using “compmgmt.msc /computer:[remote computer]” from there you can manage user accounts in Local Users and Groups.

Remove Old Windows Updates Automatically using Logoff Script

Wayne Zimmerman Leave a comment

This is a great script that helps you keep those patched boxes on your network running longer and faster. This script checks to see how old the Microsoft Windows Update Uninstall folders are and deletes them based on a parameter in the script. This reduces clutter on your PC and reduces one of the major disk hogs in a corporate environment. This script should be included in the Computers Group Policy so it has Administrative access to the PC so it can actually remove the files.

Set oShell = CreateObject("Wscript.Shell")
strWindows = oShell.ExpandEnvironmentStrings("%WINDIR%")

On Error Resume Next
Set fsoFolder = CreateObject("Scripting.FileSystemObject")

Set objFolder = fsoFolder.GetFolder(strWindows)
Set colSubfolders = objFolder.Subfolders

For Each objSubfolder in colSubfolders
	If (DateDiff("D", objSubfolder.DateCreated, Date()) > 90) AND ((Left(objSubfolder.Name,3)) = "$Nt") then
		fsoFolder.DeleteFolder strWindows & "\" & objSubfolder.Name, TRUE
	End If
Next
