Microsoft’s quiet deprecation of the long-relied-on WMIC command has finally caught up with Windows users who still reach for ancient terminal commands to check their PC specs. Combined with Windows 10’s end of support in October 2025, the landscape of system diagnostics in 2026 demands a fresh look at the tools built into Windows 11—and the few that still hold on in the aging OS.

The Deprecation You Missed

WMIC, the command-line interface to Windows Management Instrumentation, had been the go-to for quick, scriptable system inventories since the Windows XP era. Microsoft marked it as deprecated years ago, and in current Windows 11 builds it may be absent entirely. Yet plenty of online tutorials still push wmic commands as the first step to check hardware. That advice is now harmful, leaving users staring at a cryptic error or—worse—blindly trusting that old output.

The replacement is PowerShell’s Get-CimInstance, which talks to the same WMI repository but uses modern, actively supported cmdlets. For example, instead of wmic cpu get name, you now run Get-CimInstance -ClassName Win32_Processor | Select-Object Name. The result is identical, but the toolchain is not. If you’re copying commands from a five-year-old forum post, throw it out.

This shift matters because Windows 11 continues to tighten security and remove legacy components. The classic Control Panel path to system info was already hidden behind Settings in Windows 10, and Windows 11 pushes even more users toward the streamlined About page. If you’re clinging to old habits, you’re not just slower—you’re missing information that the newer tools surface more clearly.

The Modern Toolkit

Windows 11 still ships with a deep bench of diagnostic utilities. The trick is matching the tool to the urgency and depth of the question.

The 10-Second Summary

When a software installer or support agent asks for your processor, RAM, or Windows version, the fastest route is Settings > System > About. Right-click the Start button, select System, and scroll. You’ll see Device name, Processor, Installed RAM, System type (64-bit or 32-bit), and under Windows specifications, Edition, Version, and OS build. The keyboard shortcut Windows key + Pause lands you on the same page if your keyboard has a Pause key.

This is the “elevator pitch” of your PC. It’s not exhaustive—storage capacity and GPU details are elsewhere—but it covers the essentials for most quick compatibility checks.

The Support-Ready Inventory

For a thorough, exportable report, System Information (msinfo32) remains the gold standard. Press Windows key + R, type msinfo32, and hit Enter. The System Summary shows the manufacturer, model, BIOS version, Secure Boot state, installed physical memory, and a host of other details that a support technician might request. Running it as administrator (right-click in Start after searching for it) can reveal additional protected information about drivers and services.

System Information also lets you export reports: File > Save creates an .nfo file that can be reopened by the tool, while File > Export produces a plain-text inventory. As first reported by Technobezz, these reports can contain sensitive details like device names and network configuration, so review them before sharing publicly.

The Graphics and Gaming Deep-Dive

When a game refuses to launch or you’re checking VRAM against a minimum spec, DirectX Diagnostic Tool (dxdiag) is indispensable. Launch it by typing dxdiag into the Run dialog. The System tab confirms the DirectX version installed, while the Display tab(s) list the GPU name, manufacturer, driver version, and total display memory. For laptops with both integrated and discrete GPUs, you may see multiple Display tabs; make sure you’re reading the right one.

A common pitfall: the DirectX version on the System tab is not the same as the GPU’s supported feature levels. A GPU might support DirectX 12 Ultimate features while the baseline DirectX version listed is 12. Always cross-check the Feature Levels on the Display tab for true compatibility.

Real-Time Performance Monitoring

Task Manager has grown from a simple process killer into a capable hardware monitor. Press Ctrl + Shift + Esc and switch to the Performance tab. Each hardware category—CPU, Memory, Disk, GPU—shows both static specs and real-time utilization. Under CPU you’ll find base speed, cores, logical processors, and virtualization status. Memory reveals speed, form factor, and slots used. Disk identifies whether a drive is SSD or HDD on supported hardware. GPU lists dedicated and shared memory, driver version, and DirectX support.

This view is ideal when you suspect a component is bottlenecking your workflow. For instance, a CPU pegged at 100% while the GPU idles might indicate a gaming bottleneck you can solve by raising graphics settings.

Scriptable Inventories for IT Admins

PowerShell is the command-line habitat for 2026. The Get-ComputerInfo cmdlet returns a sweeping hardware and OS summary. For targeted queries, Get-CimInstance is the workhorse. To pull processor details:

Get-CimInstance -ClassName Win32_Processor |
    Select-Object Name, NumberOfCores, NumberOfLogicalProcessors, MaxClockSpeed

To list fixed drives with capacity in GB:

Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DriveType=3" |
    Select-Object DeviceID,
        @{Name="SizeGB";Expression={::Round($_.Size/1GB,2)}},
        @{Name="FreeGB";Expression={::Round($_.FreeSpace/1GB,2)}}

These commands can be dropped into scripts for fleet inventory, eliminating the need for third-party tools on managed devices.

Device Manager: The Surgical Scalpel

When you need to inspect a single component’s driver version or hardware ID, Device Manager is still the place. Right-click Start, open it, expand a category (say, Display adapters), right-click the device, and choose Properties. The General tab shows device status; Driver reveals the provider, date, and version; Details exposes hardware IDs for matching against driver databases.

A yellow warning icon signals a problem. Double-click the device to read the error code—it’s often the fastest clue when something has gone sideways.

For Home Users, Admins, and Developers

Home Users: Stick to the GUI

If you’re installing TurboTax or checking whether your machine can run a new game, the Settings About page and dxdiag’s Display tab will answer 90% of your questions. Don’t wade into PowerShell unless a trusted guide gives you a specific command to copy and paste. And never, ever share your Device ID or Product ID on a public forum; those identifiers can be used for support queries, but they’re also pieces of your system’s identity that belong in private channels only.

IT Admins: Script and Standardize

For a fleet of machines, leverage systeminfo in Command Prompt (still available, and quick) for a one-file summary, or use msinfo32 /report to generate text reports. For automated inventories, invest in PowerShell scripts that use Get-CimInstance and pipe results to CSV. Microsoft Intune admins can also view hardware inventory for enrolled devices in the admin center—a cloud-based alternative to on-premises inventory.

Developers: Know Your Toolchain

Whether you’re testing on real hardware or profiling an app, you need exact driver versions and feature levels. DxDiag’s display output is more detailed than Task Manager’s GPU tab; export it with “Save All Information” for a text file you can attach to a bug report. And when you need programmatic access, .NET developers can reach into WMI via System.Management, but for quick checks, the PowerShell cmdlets are the fastest path.

One Warning: Never Share These Identifiers

All the tools spill unique numbers that identify your installation. The Device ID and Product ID from Settings About, the serial number shown in System Information, and the hardware IDs in Device Manager are not for public eyes. Posting them in a screenshot can invite pranks at best and license misuse at worst. If a support channel asks for them, make sure it’s a trusted, private channel. When sharing a System Information report, consider exporting only the sections you need rather than the entire .nfo file.

The Windows 10 Factor

Windows 10 reached end of support on October 14, 2025. The tools described here still work on a patched Windows 10 machine, but that OS will no longer receive security updates. If you’re checking specs on a Windows 10 PC to decide whether it can upgrade to Windows 11, pay special attention to the processor, TPM version (checkable via tpm.msc), and Secure Boot state in System Information. Microsoft’s PC Health Check app is the simplest way to get a yes/no answer, but the manual checks remain reliable.

For those still on Windows 10, the Settings About page is slightly different—it may still link to the classic System Control Panel—but the core tools (msinfo32, dxdiag, Task Manager) are identical. Just remember that support has ended, and third-party driver updates will dry up over time.

What’s Next for Windows 11

Microsoft is slowly unifying hardware information into the Settings app. The Storage page already does a better job than File Explorer at showing capacity and partition layouts, and Disks & volumes can reveal unallocated space or recovery partitions that older tools miss. Expect future Windows 11 feature updates to fold more of Task Manager’s Performance tab data into Settings, perhaps under a dedicated “Hardware” section.

As AI-driven support becomes more common, having a quick, text-based inventory will grow even more important. PowerShell’s Get-ComputerInfo already provides a structured output that could be piped directly into a support chatbot. Learning to use it now will prepare you for the help workflows of tomorrow.

Checking your PC’s specifications in 2026 isn’t about memorizing command-line switches; it’s about knowing which tool to open when. With WMIC gone and Windows 10 fading, the built-in diagnostics are more capable than ever—once you leave the outdated tutorials behind.
