Download & verify ISO ​

You need a Windows ISO before you can create a bootable USB or reinstall from within Windows. Download an official image and verify it is intact before continuing.

Before downloading, confirm your PC can run Windows 11.

Installing Windows 10?

Windows 10 has no TPM or Secure Boot requirement. You can skip this table and proceed to download.

2. Download the ISO ​

These buttons request the latest Windows 10 or Windows 11 ISO from Microsoft servers through the MSDL API. JavaScript must be enabled.

Downloader logic adapted from Microsoft Software Download Listing (AGPL-3.0-or-later).

The downloader above fetches the latest ISO directly from Microsoft's servers. JavaScript must be enabled.

Manual download ​

Use the options below if the downloader does not appear, a request fails, or you prefer Microsoft's own pages.

  1. Open the Windows 11 download page.
  2. Under Download Windows 11 Disk Image (ISO) for x64 devices, select Windows 11 (multi-edition ISO) and click Download.
  3. Select your language and click Confirm.
  4. Click 64-bit Download.

3. Verify the ISO ​

A damaged or altered ISO causes setup failures, blue screens, or instability after install. Verify before writing to USB or mounting.

  1. Open Command Prompt or Terminal as administrator.

  2. Run, replacing <path_to_iso> with the actual path:

    cmd
    certutil -hashfile <path_to_iso> SHA256

  3. Compare the printed hash with a second independent download from the same source. If the values differ, delete the file and download again.

INFO

Microsoft publishes many edition and language variants, so this site does not list every official SHA-256. Comparing two independent downloads from the same source is a reliable consistency check. For more detail, see Verify Windows ISO integrity.
