Introduction:
In the world of IT administration, the ability to quickly identify a system’s critical details—from hostname and IP address to CPU load and storage capacity—is paramount. The classic Sysinternals tool, BGInfo, has long served this purpose, but it has limitations. Now, a new open-source alternative, PowerBGInfo, is changing the game. This PowerShell module (created by Przemyslaw Klys) doesn’t just place text on a wallpaper; it transforms your desktop background into a dynamic, scriptable, and visually powerful dashboard that can integrate with virtually any data source, from APIs to Active Directory and even your Remote Monitoring and Management (RMM) tools. With its ability to generate charts, topology diagrams, and highly customized layouts, PowerBGInfo elevates system information display from a simple aid to a core component of IT asset management and security monitoring.

You Should Know:
1. Installation and Your First System Dashboard
PowerBGInfo is designed for simplicity and is a complete rewrite that no longer depends on other modules, making it easier to maintain. It works with PowerShell 5.1 and PowerShell 7+ across the latest Windows versions, though Linux support is not currently a development focus, as confirmed by the author.
Step‑by‑step guide explaining what this does and how to use it.
The first step is to install the module directly from the PowerShell Gallery. This is a one-time setup on any machine where you wish to use PowerBGInfo.
Install the PowerBGInfo module (run as Administrator) Install-Module PowerBGInfo -Force -Verbose Once installed, you can update it to the latest version using the same command Install-Module PowerBGInfo -Force -Verbose
The `Install-Module` command downloads and installs the module from the official PowerShell repository. Once installed, you can create a basic wallpaper that displays your computer’s hostname and operating system. The following script generates a new background for the primary monitor (-MonitorIndex 0), applies it to your desktop, and saves its configuration.
Create a simple, functional BGInfo wallpaper
New-BGInfo -MonitorIndex 0 {
Add the computer's hostname in red, size 24
New-BGInfoValue -BuiltinValue HostName -Color Red -FontSize 24
Add the OS name
New-BGInfoValue -BuiltinValue OSName
Add the current username
New-BGInfoValue -BuiltinValue FullUserName
} -ConfigurationDirectory 'C:\ProgramData\PowerBGInfo' -WallpaperFit Fill
This command showcases the core of PowerBGInfo’s functionality. The script block `{ … }` defines what information appears, how it looks, and where it’s placed. By default, items are stacked vertically, but you can control placement with parameters like `-PositionX` and -PositionY. The `-ConfigurationDirectory` is where PowerBGInfo caches generated images and settings, which is crucial for multi-user environments.
2. Extracting and Visualizing Deep System Data
PowerBGInfo shines in its ability to pull in virtually any piece of system data you can imagine. You’re not limited to the built-in values. For system administrators, the ability to directly query Windows Management Instrumentation (WMI) and the Common Information Model (CIM) is a game-changer for creating detailed hardware and software inventory displays.
Step‑by‑step guide explaining what this does and how to use it.
This example demonstrates how to use custom PowerShell commands within PowerBGInfo to get precise disk information. The script fetches all physical drives and their associated volumes, then creates a value for each drive showing its free space. This provides an immediate, at-a-glance view of storage health.
New-BGInfo -MonitorIndex 0 {
Display basic system info
New-BGInfoValue -BuiltinValue HostName -Color Cyan -FontSize 18
New-BGInfoValue -BuiltinValue CpuName
New-BGInfoValue -BuiltinValue RAMSize
Add a section label for drives
New-BGInfoLabel -Name "Drive Health" -Color Yellow -FontSize 16
Fetch and display detailed disk information
foreach ($Disk in (Get-Disk)) {
$Volumes = $Disk | Get-Partition | Get-Volume
foreach ($V in $Volumes) {
if ($V.DriveLetter) {
$freeSpaceGB = [bash]::Round($V.SizeRemaining / 1GB, 2)
New-BGInfoValue -Name "Drive $($V.DriveLetter):" -Value "$freeSpaceGB GB Free"
}
}
}
} -ConfigurationDirectory 'C:\ProgramData\PowerBGInfo'
This script highlights a critical security and operational advantage: immediate visibility into potential issues. An administrator can instantly see if a drive is critically low on space, a common precursor to system instability or application failure. To get a raw list of all available WMI or CIM classes for querying, you can use these PowerShell commands, which are also useful for auditing:
Get a list of all WMI classes (for older systems) Get-WmiObject -List Get a list of all CIM classes (modern PowerShell) Get-CimClass -List A quick example: Get detailed BIOS information Get-CimInstance -ClassName Win32_BIOS
3. Security Implications: Auditing and Hardening
While PowerBGInfo is a powerful administrative tool, it’s important to consider the security implications of displaying system information on a desktop. The same visibility that helps administrators can also aid a malicious actor with physical or remote access. However, this risk can be mitigated by using the tool as part of a broader security and compliance strategy.
Step‑by‑step guide explaining what this does and how to use it.
A security-conscious approach is to display “posture” information—indicators of a system’s security health—rather than solely static identifiers. This transforms a passive informational tool into an active security control. The following script demonstrates how to create a security dashboard that shows critical configuration statuses.
New-BGInfo -MonitorIndex 0 {
New-BGInfoValue -BuiltinValue HostName -Color LimeGreen
New-BGInfoLabel -Name "Security Posture" -Color Red -FontSize 18
New-BGInfoValue -Name "Real-time Protection" -Value $(Get-MpPreference).DisableRealtimeMonitoring -Color Red
New-BGInfoValue -Name "Firewall Status" -Value $(Get-NetFirewallProfile -Name Public).Enabled
New-BGInfoValue -Name "Last Windows Update" -Value $(Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn
} -ConfigurationDirectory 'C:\ProgramData\PowerBGInfo'
This wallpaper can immediately alert a user or administrator if a critical security feature, like Microsoft Defender’s real-time protection, is turned off. For organizations with strict compliance mandates (like ISO 27001 or NIST), this provides an auditable and highly visible method of endpoint verification. Furthermore, you can use PowerShell’s security auditing capabilities to detect vulnerabilities on the system itself, such as the infamous “Leaked Wallpaper” vulnerability (CVE-2024-38100) which could allow privilege escalation via theme files. A proactive script could check for related patch levels and display a prominent warning if the system is vulnerable, turning your wallpaper into a dynamic security indicator.
4. Automation and Deployment at Scale
The true power of PowerBGInfo is realized when you automate its deployment. For system administrators managing hundreds or thousands of desktops, manually configuring wallpapers is impossible. Group Policy, login scripts, or configuration management tools like Microsoft Endpoint Configuration Manager can be used to run PowerBGInfo scripts automatically, ensuring every endpoint has a consistent, up-to-date information display.
Step‑by‑step guide explaining what this does and how to use it.
A common deployment strategy is to use a Windows domain’s Group Policy to run a PowerShell script at user login. This script applies the PowerBGInfo wallpaper for both the current desktop and the lock screen, ensuring consistency. To apply the wallpaper to the lock screen and for all users on the machine, you would use the `-Target Both` and `-AllUsers` switches.
A script designed to be run via Group Policy or a startup script
This applies the wallpaper to the desktop AND the Windows logon/lock screen for all users
New-BGInfo -MonitorIndex 0 -Target Both -AllUsers {
New-BGInfoValue -BuiltinValue HostName
New-BGInfoValue -BuiltinValue IPAddressv4
New-BGInfoValue -Name "Support" -Value "[email protected]"
} -ConfigurationDirectory 'C:\ProgramData\PowerBGInfo' -WallpaperFit Fill
For added security, you can run this setup in a highly restrictive environment like Windows PE (WinPE), though the author notes that compatibility depends on whether the environment supports standard wallpaper APIs. To automate the process without any visible pop-ups or user interaction, you can use the Task Scheduler to trigger the script on a schedule, such as every hour, to keep information refreshed on systems that remain on for long periods.

What Undercode Say:
- PowerBGInfo is a Strategic Asset: It transforms a visual static element (the desktop background) into a dynamic, scriptable dashboard, enhancing situational awareness for both users and IT teams.
- Security through Visibility: By cleverly integrating with PowerShell’s security cmdlets (like
Get-MpPreference), PowerBGInfo provides an immediate, visual indicator of a machine’s security posture, aiding in rapid detection of misconfigurations or compromised settings. - Future-Proof and Extensible: Its architecture, which is built to pull data from any source (WMI, APIs, etc.), means its relevance will only grow. As IT environments become more complex with hybrid cloud and zero-trust models, having a centralized, flexible tool to surface critical identity and security data directly on the endpoint is invaluable.
Prediction:
As PowerShell continues to be a cornerstone of Windows administration, tools like PowerBGInfo will evolve from nice-to-have utilities into essential security and management platforms. We will likely see community-driven modules that integrate directly with Security Information and Event Management (SIEM) systems, allowing a wallpaper to display real-time threat intelligence or live user behavior analytics. The concept of a “static” desktop wallpaper is dead; the future of the endpoint’s visual interface will be dynamic, data-driven, and security-focused, with PowerBGInfo leading the charge in the Microsoft ecosystem.
