This month's Microsoft Patch Tuesday looks like a record one, but let's look at it a bit closer to understand what is happening
The update patches a total of 243 vulnerabilities. However, 78 of them are Chromium issues affecting Microsoft Edge. Patches for Edge were released earlier. This leaves 165 vulnerabilities that are not Edge-related. Of these, 8 are rated critical, and 154 are important. One vulnerability has already been exploited, and another was made public before today but has not yet been seen in the wild.

[MEDIUM] Patch Tuesday - April 2026
Microsoft is publishing 167 vulnerabilities on April 2026 Patch Tuesday . Microsoft is aware of exploitation in the wild for one of today’s vulnerabilities, and public disclosure for one other. Microsoft evaluates 19 of the vulnerabilities published today as more likely to see future exploitation. So far this month, Microsoft has provided patches to address 80 browser vulnerabilities, which are not included in the Patch Tuesday count above.
## Increasing volumes of vulnerabilities
Regular Patch Tuesday watchers will know that these vulnerability totals are significantly higher than usual, especially the browser numbers. Late last week, Microsoft published patches to resolve more than 60 browser vulnerabilities in a single day, which is a new record in that very specific category.
