Is there an official source for Windows ISO (XP+) checksums, online?
Wanting to download some older Windows versions, for support purposes, but they don't appear to be available on Microsoft's website, so I am having to find 3rd party copies.

An MSDN subscription is not needed to browse the contents on the Subscriber Downloads page.
Once there, you can browse to any product and click on the Details
link to see the SHA1 hash for the product
for ex.: Windows XP Service Pack 3 (x86) - CD (English)
Windows XP Service Pack 3 (x86) - CD (English)

Copied from another answer...
Service Pack 2 and Service Pack 3 are available from Microsoft here: http://catalog.update.microsoft.com/v7/
You must use Internet Explorer 6 or later.
Search for "XP Service Pack" (without quotes)

There is third-party service to acquire MS Windows ISO checksums:
