Why an MSP manages this

Reading the list is the easy part

Nobody running a business reads all of them, and nobody should have to. The work is deciding which ones matter today, testing the fixes, getting them onto every PC and Mac without breaking the workday, and proving it was done.

  • 01

    Triage that starts with the exploited ones

    Most of these fixes can ride the normal monthly rollout. A handful need action the same day. Telling them apart, every month, on every machine, is the core of the work, and it is the part an office manager rarely has time for.

  • 02

    Testing before everyone gets it

    Updates go to a test ring and a pilot group first, so a broken accounting package or design tool shows up on two machines instead of forty, and the rollout pauses until it is sorted.

  • 03

    Restarts that don't wreck the workday

    Windows updates usually need a restart and macOS updates often do. Deadlines, maintenance windows and grace periods get the fix installed without forcing a reboot in the middle of a client call.

  • 04

    Macs managed as seriously as PCs

    Windows patching tools don't patch Macs. macOS updates need their own install-by deadlines through device management, and major upgrades need the same compatibility testing a Windows feature update gets.

  • 05

    A plan for machines that can't update

    Hardware that ages out and versions past end of support stop getting every fix. They need a decision, isolate, upgrade or replace, before they become the easiest way in.

  • 06

    Proof when someone asks

    Cyber insurance applications, customer security questionnaires and frameworks such as the FTC Safeguards Rule all ask how you keep systems patched. A managed service keeps the inventory and the reports that answer them.

The ins and outs

What keeping Windows and Mac patched actually involves

Windows

  • Patch Tuesday, and the exceptions

    Microsoft ships security updates on the second Tuesday of each month, and out of band when something can't wait. This log marks the out-of-band ones.

  • Cumulative updates

    Each month's Windows update carries the earlier months' fixes, so a PC that missed one catches up with the next, as long as it actually installs.

  • Fixed first, announced later

    Some fixes ship before the vulnerability is disclosed. This log flags them, because a PC that is already current is already covered.

  • Rings, deferrals and deadlines

    Windows Update for Business and Intune let you delay updates for a test group, set an install-by deadline and give a grace period before a forced restart.

  • Known Issue Rollback and safeguard holds

    Microsoft can quietly roll back a change that breaks something, and holds back feature updates from PCs it knows will have trouble. Both explain why two PCs on the same network can be on different builds.

  • Feature updates and end of support

    Each Windows version is serviced for a fixed period. Windows 10 PCs past end of support only get security fixes through the paid Extended Security Updates program.

Mac

  • No fixed release day

    Apple publishes security updates when they are ready, often several times a month around a major release, so Mac patching runs on alerts, not a calendar.

  • Updates versus upgrades

    A point update (26.7 to 26.7.1) fixes problems. A major upgrade (Tahoe to Golden Gate) changes the system and needs the same app testing as a Windows feature update.

  • Older versions get some fixes, not all

    Apple's deployment guide says not every security issue is fixed in previous major versions. Staying a version behind is a choice with a cost, not a safe default.

  • Install-by deadlines through device management

    Without enforcement, a macOS update prompt can be put off again and again. Device management can set a deadline so the update installs on schedule.

  • Macs that age out

    When a Mac can no longer run a current macOS version, it stops getting the full set of fixes. Inventory by model and macOS version shows which ones are next.

  • Apple Business for zero-touch setup

    New Macs enrolled through Apple Business arrive already managed, so update policy applies from the first login instead of after someone remembers to enroll them.

Both platforms

  • Third-party apps aren't on these lists

    Browsers, PDF readers, accounting software, VPN clients and plug-ins patch on their own schedules. A machine can be current on Windows or macOS and still exposed through an app.

  • Firmware and drivers

    BIOS and UEFI firmware, docks and network gear get security fixes too, and they rarely update themselves.

  • Recovery keys before big changes

    Before a feature update or a major macOS upgrade, confirm BitLocker and FileVault recovery keys are escrowed somewhere you can reach.

  • Laptops that are rarely in the office

    Remote and travelling staff need updates delivered over the internet with the same deadlines as office machines, or they drift months behind.

  • You can't patch what you can't see

    An up-to-date inventory of every PC and Mac, with its version and last update, is what turns a list like this one into a finished job.
