Earlier this month, Microsoft’s Family Safety feature, primarily used by parents and schools as a set of parental controls and filters, started randomly blocking Google’s Chrome browser from opening on Windows. The first reports surfaced on June 3rd, with some Chrome users noticing the browser kept closing or wouldn’t open.

Microsoft has introduced a bug into Family Safety that specifically targets the Chrome browser and prevents it from functioning on Windows. “Our team has investigated these reports and determined the cause of this behavior,” says Chrome support manager Ellen T. “For some users, Chrome is unable to run when Microsoft Family Safety is enabled.”

Other browsers like Firefox or Opera appear to be unaffected, and some users have even found that renaming Chrome.exe to Chrome1.exe works around this issue. Schools or parents who have enabled Family Safety as part of a Microsoft 365 subscription can also disable the “filter inappropriate websites” setting in Family Safety to get Chrome up and running again, but this does leave children able to access any website.

It’s unclear when Microsoft will fix the issue, which has been ongoing for more than two weeks. We reached out to Microsoft to comment on this problem earlier this week, but at the time of publication, the company hasn’t responded.

“We’ve not heard anything from Microsoft about a fix being rolled out,” wrote a Chromium engineer in a bug tracking thread on June 10th. “They have provided guidance to users who contact them about how to get Chrome working again, but I wouldn’t think that would have a large effect.”
