Microsoft's monthly security update, known as Patch Tuesday, lands this week and will bring a large batch of security fixes to Windows and other Microsoft products.

• What it is: Microsoft's scheduled monthly release of security patches, expected around 11-13 August 2026 depending on your time zone.
• Who is affected: Any business running Windows 10, Windows 11, or Windows Server. 2026 has consistently seen 100-200+ vulnerabilities patched per month, so this release is likely to be substantial.
• What the risk is: Delaying these updates leaves known, published vulnerabilities open on your systems, an easy target once the details become public.
• What action is needed: Make sure automatic updates are enabled and devices are allowed to restart to complete installation. If your business manages updates centrally, schedule this month's rollout promptly rather than deferring it.

We recommend treating this month's update as a priority rather than deferring it, given the volume of fixes expected.
