The June 2026 Secure Boot Certificate Expiry: What You Need to Know

on
If you dual-boot or run a Linux distribution with Secure Boot enabled, you may have heard about a major security deadline. The original Microsoft 2011 UEFI Third-Party Certificate Authority (CA) keys, which most Linux distributions rely on to sign their initial bootloaders (shim) on consumer PC hardware, expired at the end of June 2026 The expiration of a certificate doesn't invalidate already-installed, signed binaries on your system; firmware doesn't check expiration dates at boot time. However, moving forward, future Linux bootloader updates and security patches will be signed exclusively using the new Windows UEFI CA 2023 key . If your motherboard's firmware database isn't updated to trust this new 2023 key, your Linux system may eventually experience package management blocks or fail to apply critical bootloader updates. Before running updates, check if Secure Boot is active and see if your system already recognizes the 2023 certificate hierarchy. Open your termi...

Automating Your Windows Maintenance Tasks

on

Task Scheduler is a Windows utility that lets you automate tasks by creating "triggers" and "actions." Triggers define when a task should start, while actions specify what the task does. For example, you can set a task to run a system health check every Sunday at 8:00 AM or automatically back up files daily.


Automating tasks can:

  • Save time by reducing manual steps.
  • Improve system performance by ensuring regular maintenance.
  • Enhance productivity by launching applications or scripts when needed.

1. Open Task Scheduler

  • Press Win + S, type "Task Scheduler," and select the app.
2. Create a New Task
  • In Task Scheduler, click Action > Create Task.
  • Enter a descriptive name for your task (e.g., "Weekly Maintenance").
3. Set Triggers
  • Navigate to the Triggers tab and click New.
  • Choose when you want the task to start (e.g., daily, weekly, or at system startup).
  • Customize the timing and recurrence as needed.
4. Define the Action
  • Go to the Actions tab and click New.
  • Select Start a Program.
  • Enter the program or script you want to run. For example:
    • For system file checks, use: 
      cmd.exe
      In the Add arguments field, type: 
      /c sfc /scannow && dism /online /cleanup-image /restorehealth
    • To launch a specific app, browse to its executable file.
5. Add Conditions (Optional)
  • In the Conditions tab, you can refine when the task runs. For instance, set it to run only when the computer is idle or on AC power.
6. Save and Test
  • Click OK to save the task. Test it by selecting your task, right-clicking, and choosing Run.


Here are some practical uses for Task Scheduler:

  1. System Health Checks
    Automate scans with:

    sfc /scannow && dism /online /cleanup-image /restorehealth

  2. Daily Backups
    Use file copy commands or third-party backup tools to protect your data.

  3. App Launches
    Schedule your favorite productivity app to open at 9:00 AM on workdays.

  4. System Cleanup
    Run Disk Cleanup or temporary file removal scripts regularly.
