Key notes

  • Patch Tuesday comes once a month bringing security updates to all versions of Windows 10.
  • The April Patch Tuesday Updates mainly address the recent Exchange Server attacks.
  • Regardless of what Windows 10 version you are using, if you're using Exchange Server, it is advised that you apply the latest updates at once.
  • We will be looking over how this security update will affect your Windows 10 experience.

The April Patch Tuesday Updates are here, bringing security updates for everyone using the Windows OS.

These updates particularly target Windows 10 users, since the security updates vary based on which version of Windows 10 they are running at any given time.

However, some updates stand out compared to others, since certain builds receiving long-awaited fixes for critical issues, while other updates break certain versions of Windows entirely.

However, there comes a round of Patch Tuesday updates that seem to be solely focused on fixing a string of current issues, and that seems to be the case with the April updates.

Recent Exchange Server attacks prompted immediate action

According to a Microsoft Security Response Center post, this months security updates focus primarily on dealing with a series of recent attacks that have affected Exchange Servers everywhere:

This month’s release includes a number of critical vulnerabilities that we recommend you prioritize, including updates to protect against new vulnerabilities in on-premise Exchange Servers.

These new vulnerabilities were reported by a security partner through standard coordinated vulnerability disclosure and found internally by Microsoft.

Because of this threat, and the severity of the CVEs associated with it, Microsoft advises that, given recent adversary focus on Exchange, users install the updates as soon as possible to ensure they remain protected.

One thing they did mention though is that customers using Exchange Online are already protected and do not need to take any action, since the web app is always the latest version.

Further details were given in the Exchange Release blog, such as which versions of Exchange Server were affected, and how applying the latest updates will affect your security and functionality.


This concludes our overview of this month’s Patch Tuesday Updates, and we hope those of you that use Windows 10, as well as Exchange Server, will now have a better idea of whether to apply these updates or postpone them a little while longer.

However, keep in mind that in two weekes Microsoft will release a new set of update that will usually act more as patchfixes than actual updates, so any problems you might find may be fixed by then.

All in all, there are very few exceptions when Patch Tuesday updates should not be applied, so if you don’t have any good reasons not to, go ahead and download and install them.
