Windows is packed with capable software that most people either ignore or uninstall, even though these tools can make everyday work noticeably smoother. I want to focus on five specific free Windows apps you have probably never used, but should, drawing on recent reporting about underrated utilities, obscure alternatives and optimization choices. Each one is either built in or bundled at no extra cost, so the only investment is a few minutes to install, pin and actually try them.
1. Snipping Tool and Snip & Sketch (Screen capture done right)
Snipping Tool, together with the newer Snip & Sketch interface, is one of those free Windows apps you have probably never used properly, even though it ships with Windows and is highlighted among 5 powerful Windows tools that many people overlook. The core idea is simple: press Windows + Shift + S, drag a box and you instantly capture a region, window or full screen, then annotate it with a pen, highlighter or crop before saving or pasting. Instead of juggling third party screenshot utilities, you can capture a bug report for IT, mark up a design change for a colleague or grab a receipt from your browser without leaving the desktop. The tool supports delayed captures, so you can trigger a countdown to grab menus that disappear when you click, and it respects multiple monitors, which is crucial for remote workers who live in Teams or Zoom all day.
In practice, this built in app becomes a quiet productivity multiplier, because it replaces long written explanations with a single annotated image. For support teams, that means clearer tickets and fewer back and forth emails; for teachers or trainers, it turns any part of the Windows interface into a quick visual tutorial. The same reporting that calls out Snipping Tool as underused also lists other utilities like Reliability Monitor and Task Scheduler, which shows how often Windows hides serious capability behind bland names. I find that once users pin Snip & Sketch to the taskbar and learn the keyboard shortcut, they stop hunting for browser extensions or paid tools, and they start documenting problems, UI ideas and workflows in seconds instead of minutes, which directly improves how fast teams can diagnose issues or share knowledge.
2. Windows Sandbox (A disposable test PC inside your PC)
Windows Sandbox is another free Windows app you have probably never used, but should, because it effectively gives you a temporary, isolated Windows desktop that disappears when you close it. It appears alongside Snipping Tool in lists of free built in Windows apps that many daily users ignore, even though it can dramatically reduce the risk of running unknown software. When enabled on supported editions, Sandbox launches a clean environment that shares your system’s kernel but keeps files, registry changes and installed programs separate from your main installation. You can drag an untrusted installer into the Sandbox, run it, see what it does and then close the window, at which point every trace is wiped. For anyone who downloads utilities from forums, tests beta tools or opens suspicious attachments, this is a practical safety net that costs nothing and requires no extra virtual machine license.
The stakes are clear for IT departments and security conscious individuals, because malware and unwanted toolbars often arrive bundled with seemingly harmless utilities. By routing those first runs through Windows Sandbox, administrators can evaluate behavior before allowing software onto production machines, which aligns with the broader push toward zero trust practices. Power users can also use Sandbox to trial registry tweaks, scripts or configuration changes without risking their main profile, which is especially useful when experimenting with obscure Linux inspired workflows that are discussed in coverage of obscure Linux distros. I see Sandbox as a bridge between that experimental culture and everyday Windows safety, giving curious users room to explore while keeping core systems stable and reducing the support burden when something goes wrong.
3. Quick Assist (Remote help without extra software)
Quick Assist is a built in remote support app that many people do not realize is already installed, even though it sits alongside other handy built in Windows apps that quietly ship with the operating system. The app lets one person generate a security code and share it with a trusted helper, who can then view or control the desktop over the internet without either side installing third party tools. For families, this means you can fix a parent’s printer issue or browser problem from across town; for small businesses, it provides a no cost way for in house “power users” to support colleagues. The connection uses Microsoft’s own infrastructure, integrates with standard Windows security prompts and can be ended instantly by either party, which is important in environments where compliance and privacy rules are strict.
From a broader perspective, Quick Assist reduces friction around remote troubleshooting, which has become a central issue as hybrid work normalizes. Instead of walking non technical users through complex VPN setups or asking them to install unfamiliar remote desktop clients, support staff can rely on a tool that is already present and tied to the same update channel as the rest of Windows. That simplicity matters for organizations that want to keep their app footprint small, a goal echoed in coverage of Windows 11 apps to uninstall for a cleaner experience. I find that once teams adopt Quick Assist as the default first step for help requests, they shorten resolution times, cut down on travel for on site visits and give less technical staff a more reassuring, guided way to learn new workflows, all without paying for an extra remote support subscription.
4. Microsoft Lists (Structured tracking without spreadsheets)
Microsoft Lists is a free app for many Microsoft 365 users that behaves like a modern, shareable database, and it is frequently described as the most useful Microsoft 365 app people have never heard of. Reporting on this underrated Microsoft app highlights how Lists lets teams track issues, assets, content calendars or customer requests in a structured way, without falling back to overloaded spreadsheets or long email threads. You can start from templates for things like event itineraries or bug tracking, define columns with choice fields, dates and people, and then view the same data as a grid, calendar or gallery. Because it is part of the Microsoft 365 ecosystem, Lists integrates with Teams, so a channel can have a tab that shows a live list where everyone can add or update items in real time, with comments and alerts.
For Windows users who already have Microsoft 365 through work or school, this effectively becomes a free app that replaces a patchwork of personal task tools and ad hoc trackers. The stakes are significant for small teams that cannot justify separate project management subscriptions but still need accountability and visibility into work. By standardizing on Lists, they gain version history, permissions and automation hooks through Power Automate, which can trigger notifications or approvals when list items change. I see this as especially valuable for departments that currently manage work in shared Excel files on network drives, because moving to Lists reduces file locking conflicts and makes it easier to filter and slice information. In that sense, Microsoft Lists fits the theme of free Windows apps you have probably never used, but should, by turning an existing license into a more disciplined, collaborative workflow tool without extra cost.
5. Reliability Monitor (A timeline of your PC’s health)
Reliability Monitor is one of the most quietly powerful diagnostic tools in Windows, and it is singled out alongside Snipping Tool, Windows Sandbox, Quick Assist and Task Scheduler in coverage of Windows computer memory and hardware issues that users struggle to interpret. Accessible through the search box by typing “reliability,” it presents a day by day stability index from 1 to 10, with icons marking application crashes, driver failures, Windows updates and hardware errors. Clicking any entry reveals technical details and links to check for solutions, which turns a vague complaint like “my PC has been weird lately” into a concrete timeline of what changed and when. For example, if a system started freezing after a specific graphics driver update, Reliability Monitor will show that event on the same day as the first critical error, giving both home users and IT staff a clear starting point for rollback or further investigation. The implications for troubleshooting and long term maintenance are substantial, because this tool helps distinguish between software instability and deeper hardware problems such as failing memory or storage. When combined with advice on installing focused utilities instead of bloated suites, Reliability Monitor supports a more data driven approach to keeping Windows lean and responsive. I find that once users learn to consult it before reinstalling apps or resetting Windows, they can often pinpoint a single misbehaving program or driver and remove it, which aligns with guidance on uninstalling unnecessary Windows 11 apps for a smoother experience. For organizations managing fleets of PCs, training help desk staff to read Reliability Monitor reports can shorten diagnostic calls, reduce unnecessary hardware replacements and provide evidence when a particular third party application is consistently degrading system stability across multiple machines.
