I would highly recommend not using this one ^^, as the target will
change over time and can require specific user agent strings to work
if they decide to try to protect you from installing something that
won't work for your current OS. It is useful to keep this link as a
comment for when you want to update, but I would not recommend baking
it into a script.

This one will not change target over time ^^, though it can disappear*.

Microsoft has been using these "permanent" GUID links for years and
hasn't touched them, but the download ID links have a tendency to
change target after a while. For example, this page has ID-based
links for old versions of Silverlight:
But be warned that if you try to use them then it will _always_ give
you the most recent version (and you have to have EXACTLY the right
user agent string). So, if you provide an old Windows XP Firefox UA
string then you can get it to download Silverlight 5.1.30514.0:
However, if you kept the GUID link back when it was findable then that
will continue to work. For example, this is the (still working) link
that I have for Silverlight 1.0.30715.0 from 2008:
Which, as of this moment, is not indexed by Google. Though it will be
when this email shows up in our archive ;)
* This is _very_ rare, but it happens occasionally when security
vulnerabilities are issued.
