How long to get rid of smartscreen warning after signing code?

I forgot about this question but got resolved since then.

It took a couple of days, and couple of downloads, but it have gone away.

Since then we moved to EV cert for a different reason, but standard ones are still fine.

It's difficult to give accurate numbers here, since there is a whole bunch of information that SmartScreen might use to decide upon trustworthiness. So, keep in mind that your mileage may vary greatly.

Nevertheless, I'll try to summarize some inofficial numbers given by various people here:

• 42 days and about 1.400 app installs. Source: my own certificate (Feb 2021)
• 16 days and about 2.000 app installs. Source: my own certificate (May 2020)
• One month and more than 10.000 downloads. Source: here (Jan 2020)
• Between a few weeks and a month. Source: here (Dec 2019)
• About 2-3 weeks. Source: here (Dec 2019)
• About 3.000 downloads. Source: here (Dec 2013)
