Wireless Support WinRE 10 – Part Two

In my blog “Wireless Support WinRE 10 – Part One”, I explored an idea of using Windows 10 WinRE.wim image and an optional component (Feature Pack) called WinPE-WiFi-Package to provide support for adding wireless drivers to WinRE. My understanding is that WinRE.wim is just a modified version of a WinPE image, so I can use all the tolls and scripts available for customization of WinPE images.
Here, I will use PowerShell script to automate process of creating WinRE with wireless support.

How this script – Create-BootableWinReUSBDrive.ps1 automate process
1. You need to have Windows Assessment and Deployment Kit (Windows ADK) installed
2. Download package from the download section, under Application folder. After you download the file, please do the following:
3. Unzip the file (in my example C:\ WinRE-Wireless).
4. Connect your external USB Drive to your computer.
5. Find the PowerShell script named: Create-BootableWinReUSBDrive.ps1 (Important: there are two files: Create-BootableWinReUSBDrive.ps1 and WinRE-Build.ps1).
6. Ran as administrator the script named Create-BootableWinReUSBDrive.ps1, which opens a form as an interface to collect all necessary info for the second script named WinRE-Build.ps1 and create Media files that are necessary to make the external USB drive bootable.

Again, this is a two steps process, as described in my previous blogs and shown in the picture below:

Picture 01: in the first step you make your selections and start creating Bootable Media files.
During the first step, please make your selection: select the 32 or 64 Bit Architecture, custom (HTA or PowerShell) tool for WinRE boot option menus, the WinRE.wim file source folder, and the source folder named WinRE-Wireless by clicking ‘Browse Source’ button; once this folder is selected, please click ‘Start’ button to start creation of the Media files (i.e. the files and applications essential for booting USB drive). Important: do not close PowerShell Command line windows as shown below.

Once all Media files are created, please proceed to the second step in order to make External USB Drive bootable. First click on ‘View Drive(s)’ button to display all available drives. Click the radio button to select the file system (FAT 32 or NTFS) to be used to format external USB drive(s). Finally, click ‘Run’ button to format selected USB drive(s) and copy all Media files.
Important: The column named ‘Partition Type’ with its green / red background color will help you distinguished the USB drive that reports itself as Fixed/Removable. The Removable USB drive should not be used with FAT32 option which creates two partitions.

Picture 03: Select a drive, click a radio button and finally click the ‘Run’ button to format the selected drive and copy Media files to the selected USB drive.

Finally, at the end of the second step, you will have a bootable USB drive with WinRE image, wireless support and custom menu option created. If you boot your computer using this USB drive you will see the menu option for Custom Tool (in my example HTA tool) and WinRE detecting Wi-Fi networks.

To download the WinRE-Wireless application, please go to the site’s download section, and expand the Application folder. In the compressed download file I’ve included a script to export WLAN profile(s).


Wireless Support WinRE 10 – Part One

It seems that many people need to be able to connect to a wireless network via WinPE. In addition, a large percentage of windows systems nowadays don’t have Ethernet port and many businesses are going “wireless only”. If you browse the Internet, you will find several guides/hacks successfully used to build a WinPE with wireless support. In this blog which has two parts, I will describe the way you can use the Windows 10 WinRE.wim image and an optional component (Feature Pack) called WinPE-WiFi-Package to provide support for adding wireless drivers to WinRE, and the ability to create/deploy images over wireless network connections. In the second part I will provide PowerShell script to automate process of creating WinRE with wireless support.

Windows RE (Recovery Environment) and Optional Components

This page provides the Optional Components Reference:–optional-components-reference

The default Windows RE image contains the following built-in optional components:

•WinPE-StorageWMI-Package (added to the base image in Windows 8.1 and Windows Server 2012 R2)
•WinPE-HTA (added to the base image in Windows 10)

In addition to the list of default ones, here is our hero – WinPE-WiFi-Package

Network/WinPE-WiFi-Package is used by Windows Recovery Environment (Windows RE). This package is included in the base winre.wim file. Note that this package is used by Windows RE only, and you won’t find it in Boot.wim or ADK WinPE.wim, or as an ADK Optional Component.

Windows RE location and Extraction

Windows RE is stored as WinRE.wim file on a device hard drive or SSD in Windows 7, 8/8.1 and 10.  Windows 7 normally saves it on the same partition/volume with Windows, while Windows 8 and 10 usually keep it on the hidden System Reserved partition that also contains boot files and Boot Configuration Data (BCD).

Therefore, the OS Windows 8, Windows 8.1, and Windows 10 will place WinRE.wim in the following locations:
• Single Partition Deployments – WinRE.wim placed on C: drive (Partition 1).
• BIOS with System Partition – WinRE.wim placed on the System Partition (Partition 1).
• UEFI with Recovery Partition – WinRE.wim will be placed on the Recovery Partition (4).
Note that a UEFI system will have an EFI System Partition (1), an MST Partition (2), Windows Partition (3), and Recovery Partition (4).

To get WinRE.wim from a computer installed with Windows OS, look into Windows\System32\Recovery folder, and if you do not see it there (make sure you are viewing Hidden, System OS files) please do the following:
– run command reagentc /info to find out if it is installed and where (and if existent/installed on OS)
– run reagentc /disable to put WinRE.wim back in Windows\System32\Recovery folder so you can copy it, and then run reagentc /enable to put it back.

Picture 01: WinRE.wim file location

To get WinRE.wim from a Microsoft download file, you need to convert an ESD file (the install.esd file is a Windows Electronic Software Download file located in Sources folder) into Install.wim file. The best way to extract WinRE.wim is to create a folder on your C: drive (example C:\ESD) and copy install.esd into this folder. Open Command Prompt as Administrator, get into C:\ESD folder and run the following commands:
– dism /Get-WimInfo /WimFile:install.esd (to get information on the ESD file and find index number that you need; in my example I choose Index 1 because it is a PRO version).









Picture 02: Using DISM to get info about Install.esd

– dism /export-image /SourceImageFile:install.esd /SourceIndex:1 /DestinationImageFile:install.wim /Compress:max /CheckIntegrity

Picture 03: export/convert ESD file into WIM file

Depending on your computer, the command takes from 10-20 minutes to finish. Mount the Install.wim file and copy WinRE.wim from the Windows\System32\Recovery folder. Regardless of the method used to find Winre.wim, please always make sure to use a version of the file compatible with the version and architecture of Windows for which WinRE is being repaired. For example, if you are repairing WinRE on a Windows 8 64-bit system you should use the Windows 8 64-bit Winre.wim file.

Customizing WinRE and Boot Options Menu

You can customize WinRE.wim by adding packages, languages, drivers, and custom diagnostic or troubleshooting tools. Note that the number of packages, languages, and drivers is limited by the amount of memory available on the PC, and Microsoft, for performance reasons, recommends that you minimize the number of languages, drivers, and tools that you add to the WinRE.wim image.

The customizations steps are as follows:

1. Use DISM to mount WinRE.wim (for example C:\mount).
2. Create the \Sources\Recovery\Tools folder in the WinRE mount folder.
3. Create an .xml file called WinREConfig.xml that describes the custom tool in the boot options menu.
4. Launch Notepad.exe and type the following:

For HTA Custom Tool WinREConfig.xml

For PowerShell Custom Tool WinREConfig.xml

Note the access level as Yes/No value. It specifies whether the imaging tool should be restricted to users with administrative privileges only from the Windows RE tools menu. This setting does not affect the Recovery control panel, which always requires administrative privilege.

5. Save the file using UTF-8 coding. Do not use ANSI. Save this file in \Sources\Recovery\Tools folder.
6. Copy the custom tool in the \Sources\Recovery\Tools folder of the mounted Windows RE image.
You can only add one custom tool to the WinRE boot options menus. This tool must have .EXE extension.

HTA Custom Tool

• mshta.exe
• ACBWinPEx64.hta

Powershell Custom Tool

• powershell.exe
• ACB-WinPEx64.ps1

Picture 04: Custom tool and apps in the Sources\Recovery\Tools folder; note that I’ve used ACBWinPEx64.hta and ACB-WinPEx64.ps1 from my blog WinPE 5.0 GUI (

If you choose to have PowerShell Tool you need to add WinPE-PowerShell Optional Component.

7. Use DISM to add drivers (wireless drivers and other needed drivers)
8. Use DISM to add apps that you will use in your Recovery Environment
9. Create/export wireless profile to be used in your Recovery Environment

netsh wlan export profile name=”WiFi_SID_Name” folder=D:\ key=clear
(This would result in exporting/creating profile saved in file D:\Wi-Fi-Name.xml where D: is the USB drive)

You could use a PowerShell script instead:

function Export-WlanProfile($ProfileFolder){ 
Exports WLAN profiles 
Export-WlanProfile -ProfileFolder C:\WinRE-Wireless\WLAN-Profiles 

 If((Test-Path $ProfileFolder -PathType Container)){
 try {
 $wlanProfileCollection = (netsh wlan show profiles) | 
 Select-String -Pattern "All User Profile" | 
 Foreach-Object {$_.ToString()} 
 $wlanProfileCollection | 
 Foreach-Object {$_.Replace(" All User Profile : ",$null)} 
 $wlanProfileCollection | 
 ForEach-Object {netsh wlan export profile $_ $XmlDirectory key=clear} 
 Write-Warning "Error exporting WLAN profile(s)!"
 Write-Warning "Error: $($_.Exception.Message)"
 [System.Windows.Forms.MessageBox]::Show("Folder does not exist!")
Export-WlanProfile -ProfileFolder C:\WinRE-Wireless\WLAN-Profiles

10. Use DISM to commit your customizations steps and unmount the WinRE image
11. Format you USB drive, make it bootable and add customized WinRE image
12. Once you boot your system into WinRE with wireless support you could use PE Network Manager – to import profile for wireless network or you could type the following command:

net start wlansvc
netsh wlan add profile filename=D:\Wi-Fi-Name.xml

Microsoft, due to security considerations, recommends that that you disable networking when you don’t need connectivity. By default, networking is disabled in WinRE. You can turn on networking when you need it.
