I was excited about the Windows 8 developer preview that was released earlier tonight, so I fired up Virtual PC to start playing around with it. I ended up with an error when it was loading so I thought maybe I had a bad copy of the ISO so I thought "I know, I'll do a checksum test." Unfortunately, I don't have a tool to take a checksum on my current machine so naturally I wrote a simple function in PowerShell to do the checksum test for me.
It has only a few simple parameters that you can enter, file and algorithm. "File" is for the actual file you want to checksum. "Algorithm" is either "sha1" or "md5" and will let you get both an MD5 and a SHA1 checksum of the specified file.
Update: If you came here looking for the SHA1/MD5 hashes for the Windows 8 CTP iso’s, here you go.
