Is there a built-in checksum utility on Windows 7?

"There is a built in utility, as specified in this other answer.

You may, however, wish to use this freeware app called HashTab that integrates neatly with Windows Explorer by registering a... well, a tab in the properties dialog of files. It's pretty sweet."

"I'm using HashCheck (latest version) which integrates itself as a property page for files and includes a context menu to compare against hash check files (SFV).

It is free, and the source is available."

"The new version of 7-Zip also gives you the option of checksums just by right clicking (this doesn't include MD5). It has SHA-1, SHA-256, CRC-32, CRC-64, etc.

.

For MD5 you can download HashTab and check by right clicking and then properties."

"Here's one I've used before that integrates nicely with Explorer's ""Properties"" dialog: Summer Properties. It's open source, and an x64 version is also available.

I also like Safer Networking's FileAlyzer, which provides additional features as well. But just for checksums, Summer Properties is lightweight and does the job."

"Nirsoft's HashMyFiles is small utility that allows you to calculate the MD5 and SHA1 hashes of one or more files in your system. You can easily copy the MD5/SHA1 hashes list into the clipboard, or save them into text/html/xml file.

HashMyFiles can also be launched from
the context menu of Windows Explorer,
and display the MD5/SHA1 hashes of the
selected file or folder.

HashMyFiles is freeware and portable."
