Microsoft released its monthly security update today, fixing a large number of vulnerabilities across Windows, Office and related products.

• What it is: September's Patch Tuesday release, delivered on the second Tuesday of every month, addresses well over 150 security vulnerabilities across Windows, Office, Teams, Exchange Server and other Microsoft products.
• Who is affected: Any business running Windows desktops, Windows Server, or on-premises Exchange or Active Directory infrastructure.
• What the risk is: Unpatched systems remain exposed to known vulnerabilities that attackers routinely target once technical details become public.
• What action is needed: Ensure Windows Update is set to install automatically, or confirm with your IT provider that this month's updates have been deployed across your devices and servers.

We recommend confirming your systems have received this month's updates within the next few days.
