The CertUtil is a pre-installed Windows utility, that can be used to generate hash checksums:

CertUtil -hashfile pathToFileToCheck [HashAlgorithm]

HashAlgorithm choices: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512

So for example, the following generates an MD5 checksum for the file C:\TEMP\MyDataFile.img:

CertUtil -hashfile C:\TEMP\MyDataFile.img MD5

To get output similar to *Nix systems you can add some PS magic:

$(CertUtil -hashfile C:\TEMP\MyDataFile.img MD5)[1] -replace " ",""
