How to Checksum Files in Windows 10. There are a few ways to CheckSum files in Windows 10 listed in the great wide open of the internet.
They are as follows:
fciv (outdated from 2004)
fciv -md5 d:\programs\setup.execertutil (built into Windows)
CertUtil -hashfile C:\TEMP\MyDataFile.img MD5
get-filehash (built into PowerShell v4 and higher)
get-filehash -algorithm md5
other tools
There are other tools out there but I prefer to stick with what's built into the OS and released/blessed from the OS author.
