Windows is Microsoft’s operating system for personal and organizational computers. It provides the software environment that lets you run applications, manage files and hardware, sign in, and get work done. Windows 11 is the current Windows client version covered here; Windows 10 reached the end of general support on October 14, 2025.
What is Windows?
An operating system is the core software layer that connects a computer’s hardware with the applications and services people use. It manages tasks such as starting the computer, handling files, supporting devices, and providing a way to interact with programs. Windows is Microsoft’s operating system family for PCs. Microsoft describes Windows 11 as “a client operating system” and highlights productivity, app compatibility, security, and organizational deployment in its Windows 11 overview for administrators.
What is Windows used for?
People use Windows PCs to run desktop applications, manage documents and other files, connect hardware, and carry out personal, school, and work tasks. Organizations also use Windows for productivity, security, device management, and deployment. Microsoft says many applications and tools used with Windows 10 can also be used with Windows 11, though compatibility for a particular application or device should be checked with its maker.

Windows 11 versions and support
Windows 11 receives one feature update per year and monthly quality updates, according to Microsoft’s Windows lifecycle FAQ. Support duration depends on both the edition and the release: Home and Pro have a 24-month servicing timeline, while Enterprise and Education have a 36-month timeline. Home edition does not support deferring feature updates, so it typically moves to a newer version before the listed servicing end date. Check the exact edition and version rather than assuming that all Windows 11 PCs share one support deadline.

Windows editions
Windows 11 includes consumer and organizational editions. Home, Pro, Enterprise, and Education do not necessarily have identical features or servicing options. Before choosing a PC or edition, check whether it includes the Windows features your work requires and whether its update and support timeline fits how you plan to use it.

What is the difference between Windows 10 and Windows 11?
Windows 11 is the current client version in this guide; Windows 10’s final general-availability feature version was 22H2, and general support ended on October 14, 2025. A Windows 10 computer can still run after that date, but Microsoft no longer provides ordinary quality, feature, or security updates or technical support for it. Microsoft documents an Extended Security Updates program for some people who need to keep using Windows 10. Check Microsoft’s Windows end-of-support information to determine whether an option applies to you.

If you are still using it, check whether your PC can move to Windows 11 and whether its edition and release will meet your needs. If the device is ineligible, Microsoft’s guidance points users toward a Windows 11 PC.

Can your PC run Windows 11?
A standard Windows 11 installation requires a compatible 64-bit processor running at 1 GHz or faster with two or more cores, at least 4 GB of RAM, and at least 64 GB of storage. The PC also needs UEFI firmware capable of Secure Boot, TPM 2.0, graphics compatible with DirectX 12 or later with a WDDM 2.0 driver, and an HD display at least 9 inches diagonally. Windows 11 Home requires internet access and a Microsoft account to complete first-use setup. Some apps and features require more than these minimums; see Microsoft’s full Windows 11 requirements.
Use Microsoft’s PC Health Check app to assess a specific device rather than inferring eligibility from its age or processor brand. The app checks compatibility; it does not determine whether the PC’s performance will suit demanding applications or games. For those workloads, check the requirements of the programs you intend to use as well.

How should you compare Windows PCs or editions?
- Required features: Compare Home, Pro, or an organizational edition against the Windows features your work needs.
- Compatibility: Check the processor, memory, storage, firmware, TPM, graphics, and display requirements for the specific device.
- Support horizon: Confirm the installed Windows edition and release, its servicing end date, and its update cadence.
- Workload: Treat minimum requirements as an installation baseline, not a guarantee of good performance for demanding apps or games.
- Transition from Windows 10: Check Windows 11 eligibility and whether Microsoft’s Extended Security Updates program applies if you need to keep using Windows 10.
