    I have a few checksum values, i.e. MD5/SHA256/SHA384/etc, kept in some text files. Some of these are kept in simple cheksum file format like the one given belowXXXXYYYZZZZ..................... filename1XXX1YYY1ZZZZ1................... filename2X1X1Y1Y1Z1Z1Z1.................. filename3Some of the files that are stored in BSD Style checksums. like the one given belowSHA256 filename1 = XXXXYYYZZZZ.....................MD5 filename2 = X3X3Y3Y3Z3Z3.....................SHA1 filename3 = XX22YY22ZZ22..................I need a tool or utility that can validate these checksum values th

    efswrt.dll page hashes of an image file are not valid

    I started getting this message on Event Viewer 12/9/15 and get it every 2 to 5 days:

    Code Integrity determined that the page hashes of an image file are not valid. The file could be improperly signed without page hashes or corrupt due to unauthorized modification. The invalid hashes could indicate a potential disk device error.

    File Name: \Device\HarddiskVolume2\Windows\System32\efswrt.dll

    Event ID: 6281

    I ran DISM.exe /Online /Cleanup-image /Scanhealth and it said everything was OK.

    I saw a suggestion to run sfc /scannow, but I am concerned about doing that on my own.

    Do you have problems with hash checksum verification for Win11 ISO?

    I think it is not a matter of USB, first problem is the checksum which is not ok for every single ISO i download. Mentioned linux Mint ISO sitting on the same USB was downloaded also today and hash checksum is ok. I can use Rufus on other pc with windows but i do not have VALID ISO. I have tried to download it on two laptops and an IPad, every single one is corrupted.

    How to validate checksums/hash stored in a file against their targets

    What are the checksums/hashs for the Windows 10 2022 Version 22H2?

    That helps with downloading it but doesn't help with verifying the integrity of the ISO which is not on that page (direct link). Verifying the Hashes is most important part since this is what the Windows Media Creation Tool does. For users like myself that are downloading the ISO from a operating system that is not windows we need to do this step ourselfs (which people should do with all software downloads).

    Could you post what the SHA256 checksums are for this Windows 10 2022 Version 22H2 Release?
