Hey everyone it has been a while!

Windows deprecated support for SHA-1 and will exclusively use SHA-2 after July 2019. If you’re on Windows 7, you have to install KB4490628 and KB4474419 for it to support SHA-2. Do note you must have Service Pack 1 for Windows 7 installed to install KB4490628 and it is recommended to install KB4490628 first then reboot before installing KB4474419.

You can read about the switch to SHA-2 here

Q: What if I don’t install the said updates for SHA-2 support in Windows 7?

A: Windows 7 wont be able to install Microsoft/Windows updates from August 2019. Your system will be vulnerable to exploits and hackers. Emsisoft Antimalware may also not work correctly and/or stop updating.

Q: I’m on Windows 10, do I need to install those updates too?

A: No. The updates for SHA-2 support are only relevant to legacy OS Windows 7 SP1, Windows Server 2008 R2 SP1 and Windows Server 2008 SP2.
