The suggested HashTab tool is not useful on Windows. If you get it and check the properties tab, the sha256 sum is not there. Either additional instructions to enable it are required or a different tool should be suggested: (such as

Otherwise, reddit and/or forum could get inundated with posts from windows users who will report that their windows system got a compromised 13th version when they download it.
Thanks, I changed it to a built-in utility that SENPAI_NOTICES_YOU mentioned on Reddit.
Is Electrum still safe to use?
Probably this most recent thing doesn't change much. I consider Electrum to be reasonably safe, though not very private at all.
One way you can lose money is that the Electrum server can say that you received x BTC that you didn't really receive, and then you could irreversibly send out some product in response to this non-payment. (This might require some mining power to pull off, I'm not sure.) This is more of a threat for automated services, though.
