PC Patching Knowledge base

What does “patching” mean for my computer?

It means installing updates that fix problems or improve security.

Why do I need to patch my computer?

To keep it safe from hackers and running smoothly.

How often should I patch my computer?

Usually once a month, or whenever important updates are released.

What happens if I don’t install patches?

Your computer could be at risk of viruses, slowdowns, or even data loss.

Do patches only fix security issues?

No—they can also fix bugs and improve how your computer works.

Will patching slow down my computer?
Patching may slow down your computer temporarily during installation, but this helps your performance in the long run.
Do I need to restart my computer after patching?

Often, yes. Restarting helps the updates take effect properly.

Can I keep working while patches are installing?

Sometimes, but it’s best to save your work and let the update finish.

Can patches break my computer?

It’s rare, but possible. That’s why backups and testing are important.

What’s the difference between a patch and an update?

A patch fixes specific issues; an update might include new features too.

Do I need internet to install patches?

Yes, because your computer needs to download the latest files.

Can I schedule patches for after hours?

Yes—many systems let you choose when to install updates.

What if I miss a patch?

You can usually install it later, but it’s best not to wait too long.

Do all computers need the same patches?

Not always—it depends on the operating system and what software is installed.

Is patching different for Macs and PCs?

The process is similar, but the updates come from different sources (Apple vs. Microsoft).

What if I’m using an old version of Windows or macOS?

Older systems may not get patches anymore, which can be risky.

Can patches help prevent ransomware?

Yes—many ransomware attacks exploit unpatched systems.

Is patching just for computers?

No—phones, tablets, and even printers and routers need updates too.

Why does the patching window start at 5 pm?
This is to maximise the time that PCs are available as users often forget the patching window and the PCs are unavailable.
What happens if I close the lid on my laptop and leave?
The PC will go into sleep mode. When it is on and connected to the internet, patches will download, and you will need to restart (or defer restart) the PC.
What happens if I fully shut down (turn power off) the PC?
The patches cannot be downloaded. Chill IT has a standard patching window of 2 days per week. Patches will be pushed in the next patching window in the current week or the following week.
What happens if I don’t have access to the internet?
The patches cannot be downloaded. Vulnerabilities will not be patched during that period.
What happens if I miss my patching time?
Patches will be pushed during the next available patching window.
What happens if I defer my restart?
The restart will be delayed to the agreed time, after which the system will seek to restart automatically.
What happens if I hit snooze?
This will snooze the process 3 times before the PC updates.
Benefits of Weekly Restarts
Why is a weekly restart of my PC important?
Most security patches and updates require a system restart to take effect.

Compliance and Reporting:
Internal compliance reports flag devices that haven’t been restarted as non-compliant, which can affect your organisation’s exposure score and cyber insurance eligibility.

Risk Mitigation:
Weekly restarts help resolve security risks by ensuring patches are applied.

Operational Efficiency:
Restarting clears memory, resets system processes, and ensures smoother performance.
