Windows 10 Smartscreen

What is SmartScreen?


With the release of version 2.12 the DAX Studio installer is now signed with an EV certificate kindly donated by SQLBI Corp so Windows Smart Screen should no longer falsely flag it as potentially harmful.

SmartScreen is a set of technologies from Microsoft that is designed to protect your pc from malicious software. Unfortunately for specialty products like DAX Studio, one of the criteria that Smart Screen uses to determine if a given download is safe:

  • is the download is digitally signed and
  • has been "frequently dowloaded".

The executables, Installer and Excel Add-in are all digitally signed. But apparently the level at which something is considered "frequently downloaded" is quite high. The digital certificate used for signing also expires every 12 months and when SmartScreen sees a new signature it can also take some time for it to build up trust in that new certificate.

Digital Signature

If you right click on the installer or DaxStudio.exe in Windows Explorer and view the properties you should see a Digital Signature signed by "Darren Gosbell" (the primary developer of DAX Studio)

Can I check DAX Studio for malicious software before downloading it?

Yes, you can right click on the download button and choose the option to "copy shortcut" (the exact wording of this my vary between the various browsers). Then go to and you can submit the URL there for scanning. Virus total will the scan using a large number of AV scanners and report any issues. Typically it should report being 100% clean, but from time to time you may see a false positives often these resolve themselves within a few days.
