Script - Unzip cab and zip files

By -
The Dell driver packs located on Dells community site have recently had problems being decompressed I would get errors that would stop the decompression process. I have found that PowerShell can decompress the files correctly. So I created a script to decompress cab and zip files that works very well when you are dealing with large files. Like most of my scripts you can run it right from a PowerShell window and use the File and DecompressTo parameters or you can run the script with out the parameters to display a GUI.




<#
.SYNOPSIS
This script is used to extract a cab or zip file 

.DESCRIPTION
The Script will launch a GUI that will allow you to choose browse for a zip or cab file. Then select a folder to extract to.
You can also lauch the script with out a GUI 

.PARAMETER File
Specifyies the zip or cab file

.PARAMETER DecompressTo
Specifyies the location where the zip or cab should be decompressed to, if you do not specify this paramiter C:\Extracted_Files 
will be used by default

.EXAMPLE
Extract.ps1 -File C:\Example.cab
This will extract the cab file to C:\Exreacted_files and will not show the GUI

.EXAMPLE
Extract.ps1 -File C:\Example.zip -DecompressTo C:\Example
Extracts the zip file to C:\Example and will not show the GUI

SCCM Applications vs. SCCM Packages: Understanding the Key Differences

By -
Microsoft System Center Configuration Manager (SCCM) is a versatile and powerful tool for managing devices, applications, and updates in an organization's IT environment. Among its many features, SCCM allows you to deploy software to your end-users in two primary ways: Applications and Packages. Although both methods have a similar goal, they have some key differences that IT administrators should understand when choosing the appropriate deployment method. In this blog post, we will explore these differences and help you decide which option is best for your organization. Definition and Deployment Scenarios SCCM Applications: An SCCM Application is a high-level, user-centric deployment method that focuses on providing the desired user experience. Applications are designed to be state-based, meaning they can detect if the application is already installed and only perform the necessary actions if the application is not present or if a newer version is available. Applications are suita...

Faster PXE boot times in SCCM 1606 and later

By -
Image
A new feature introduced with SCCM 1606 was being able to modify the boot times for PXE. This is done by modifying the TFTP block and window size of the boot image RamDisk. This was originally implemented to help a admin over come network requirement. This allows us to make the PXE boot times much faster for my self this meant taking a 10 minute boot time all the way down to 30 second boot time. In order to make this change you need to create 2 registry keys on your PXE enabled DP. Location : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\DP Name: RamDiskTFTPWindowSize Type : REG_DWORD Value : <customized window size> The default value is 1 (1 data block fills the window)  Location : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\DP Name: RamDiskTFTPBlockSize Type : REG_DWORD Value : <customized block size> The default value is 4096 (4k).  once you have added the registry keys you will need to restart  the Windows Deployment Service for the ch...
