    Hi,

    For most of the products, Microsoft publishes checksums for their ISO files and downloads on the VLSC (Volume Licensing Service Centre). For the file,

    SHA-1: 718fcfe62bcae8cd2ee824a010d3edd38067419a

    I hope this information helps. If you have any more questions, don't hesitate to reach out.

    Otherwise, please take a moment to rate the answer. Wishing you good luck!

    For Windows and other Microsoft media, checksum hashes (such as SHA1/SHA256) are published only for specific downloads where Microsoft explicitly provides them, typically on the same page as the download.

    In the provided material, an example is the Safe OS Dynamic Update package for Windows 10, version 2004 and 20H2, where Microsoft lists SHA1 and SHA256 hashes for each .msu file directly in the bulletin:

    File name SHA1 hash SHA256 hash
    Windows10.0-KB4586858-x86.msu EEF391495ABE6DD1B9B9288EE6A19FB8DEEBAF73 648C5E2E6A72996418B150E42B7283C9C76265EFC209CBE83483E552A42E55F7
    Windows10.0-KB4586858-x64.msu 8713EE767680867DDCADA8C85165C06A07DA4D68 EC37BF1CD31573276E26B1552B63D146FB9C60BBB59028E624E28BF0F19D40F0
    Windows10.0-KB4586858-arm64.msu 5C94BADAC0D9929794DB1185A826F05495623729 93DD13B908EC4023C30485DC0A803A5681D08669F3EDD88F7309F831A58E5B0B

    Similarly, for monthly security release ISO images, Microsoft publishes the ISO download links on a dedicated support article, but that article does not include checksum values; it only provides the ISO URLs for each month and year.

    For ISO files such as SW_DVD9_NTRL_Win_10_2004_64Bit_MultiLang_FOD_1_X22-21311.ISO and SW_DVD9_NTRL_Win_10_2004_64Bit_MultiLang_FOD_1_X22-21313.ISO, no checksum information is provided in the supplied material. When Microsoft does publish hashes for such media, they appear on the specific download or support page for that file, in the same way as shown for the Safe OS Dynamic Update packages.
