Download Windows Installation Media Safely from Microsoft

Download Windows installation media from Microsoft or an authorized organization portal�not an ISO mirror, file-sharing site, or modified �lite� build. An untrusted image can contain malware before antivirus software is installed, and the risk is especially high for unsupported Windows versions.

Support and download status

Version	Current guidance
Windows 11	Use the current supported release from Microsoft's official download page when the PC meets its requirements.
Windows 10	Version 22H2 reached end of free support on October 14, 2025. Official reinstallation media remains available; eligible devices can use the temporary ESU program while moving to a supported system.
Windows 8.1	Support ended January 10, 2023. Do not install it for ordinary internet-connected use.
Windows 7	Support ended January 14, 2020, and the general ESU period has ended.
Windows XP	Support ended April 8, 2014. Keep it offline and isolated if legacy hardware or software requires it.

Windows 11: preferred for compatible PCs

Use the official Windows 11 download page for the Installation Assistant, Media Creation Tool, or ISO options that Microsoft currently provides. Check CPU, TPM 2.0, Secure Boot, memory, storage, graphics, and firmware compatibility before erasing an existing installation.

Windows 10: official media for reinstalling or transition use

Microsoft's Windows 10 download page provides the Media Creation Tool and ISO guidance for Home and Pro. Enterprise media is obtained through the appropriate organization portal. Match the edition, language, and 32-bit or 64-bit architecture to the license and hardware.

Windows 10 installation media

Windows 10 Home and Pro reached end of support on October 14, 2025, according to the Microsoft lifecycle page. The Windows 10 ESU program is a temporary security bridge, not a new feature release or long-term replacement.

Windows 8.1: unsupported

Windows 8.1 improved several parts of Windows 8, but the official lifecycle confirms that support ended in January 2023.

Windows 8.1 desktop and Start interface

If a licensed legacy system must be restored, use original recovery media, the computer manufacturer's recovery service, or an authorized business licensing portal. Keep the machine isolated and plan migration; a downloadable ISO does not restore security support.

Windows 7: unsupported

The familiar desktop does not offset the absence of current security and browser support. The Windows 7 lifecycle page records the end of extended support in January 2020.

Windows 7 desktop

Use an authorized organization archive, original licensed media, or vendor recovery image only for a documented legacy requirement. Do not publish or rely on unofficial Home, Professional, or Ultimate download links.

Windows XP: use only for isolated legacy needs

Windows XP is unsuitable for normal internet-connected computing. Microsoft's Windows XP lifecycle page records the end of support in April 2014.

Windows XP desktop

If an old instrument or application requires XP, isolate it from the internet and untrusted networks, restrict removable media, preserve a known-good disk image, and migrate the workload when possible. A virtual machine may help contain a legacy application, but it does not make an unsupported guest operating system secure.

Prepare before creating installation media

Back up documents, browser data, application settings, license information, and the BitLocker recovery key.
Confirm the installed edition under Settings > System > About and the activation state under Update & Security > Activation.
Download storage, network, and chipset drivers from the PC manufacturer when the machine may not have network access after installation.
Use a blank USB drive; media-creation tools erase the selected drive. Disconnect other removable drives to reduce the chance of selecting the wrong one.
Keep the PC on reliable power during creation and installation.

The Windows 10 bootable-USB guide explains UEFI/GPT and legacy BIOS/MBR choices. For installation, reset, and recovery workflows, use TipsMake's Windows installation and recovery collection.

Verify the download

Use the official URL and compare the filename, edition, language, architecture, and release with Microsoft's page. If Microsoft or an authorized administrator provides a SHA-256 checksum, calculate the local hash in PowerShell:

Get-FileHash "C:\path\Windows.iso" -Algorithm SHA256

The values must match exactly. A checksum proves that the file matches the referenced image; it is useful only when the expected checksum itself comes from a trusted source.

Activation and clean-install cautions

Installation media is not a license. Reinstall the edition previously activated on that device or provide a valid license. A clean installation can delete applications, settings, recovery partitions, and personal files. Read every partition screen carefully and stop if you cannot identify the correct target. On an organization-managed PC, obtain the image, drivers, encryption instructions, and approval from its administrator.
