Why Computer Updates Are Essential for Security and Performance

Introduction

How often have you clicked 'Remind me later' when your computer tells you an update is available? It might seem harmless, especially when you're busy, but repeatedly postponing updates can expose your business to security threats, performance problems and unnecessary disruption.



Keeping computers updated is one of the simplest ways to maintain their security and reliability. However, installing every update immediately isn't always the safest approach either.

At CED Technology, we believe updates should be managed properly, ensuring important security fixes are applied promptly while checking for known problems that could affect your computers.

Why Are Computer Updates Important?

Computer updates do much more than introduce new features. They help fix security vulnerabilities, correct software bugs, improve performance and maintain compatibility with other applications.

The UK's National Cyber Security Centre (NCSC) explains that software updates frequently contain security patches, bug fixes and performance improvements, all of which contribute to keeping devices secure and reliable.

Whether it's Windows, your web browser or everyday business applications, keeping software maintained helps prevent avoidable problems and reduces your exposure to cyber threats.

The Security Risks of Delaying Updates

Cyber criminals actively look for vulnerabilities in outdated software. Once a weakness becomes known, attackers may attempt to exploit computers that haven't received the necessary security patch.

This can potentially lead to:

• Ransomware attacks: Malicious software encrypting business files and demanding payment.
• Data breaches: Unauthorised access to confidential business or customer information.
• Malware infections: Harmful software exploiting known security weaknesses.
• Business disruption: Compromised computers or systems becoming unavailable.

The longer a critical security update is postponed, the longer a known vulnerability may remain available for attackers to exploit.

This is why the NCSC's vulnerability management guidance recommends having a clear update policy, prioritising security patches and reducing the time systems remain exposed to known vulnerabilities.

For businesses, a single compromised computer can potentially put shared files, customer information and other connected systems at risk.

How Updates Improve Computer Performance

Security isn't the only reason to keep computers updated.

Software updates can also resolve problems that affect everyday computer performance and reliability.

Common improvements include:



• Fixing bugs that cause programs to freeze or crash.
• Addressing known performance problems.
• Improving compatibility with other applications.
• Resolving issues affecting hardware or software stability.
• Introducing features and improvements that make applications more efficient.

Although updates won't necessarily make an ageing computer faster, they can help resolve software-related problems and maintain its reliability.

Keeping applications updated can also prevent compatibility problems as operating systems and other business software continue to develop.

Why Installing Updates Immediately Isn't Always Safe

While keeping software updated is essential, new updates can occasionally introduce unexpected problems.

Even major software developers such as Microsoft sometimes release updates that cause compatibility issues or affect certain devices.

These problems can include software crashes, hardware malfunctions, connectivity problems and, occasionally, computers failing to start correctly.

Microsoft even operates a system known as safeguard holds, which can temporarily prevent certain Windows feature updates from installing on devices where known compatibility problems have been identified.

The answer isn't to avoid updates, but to manage them carefully.

Checking for known issues, prioritising critical security fixes and controlling how updates are deployed can help reduce unnecessary disruption.

Importantly, delaying an update for compatibility reasons should not become an excuse for leaving critical security vulnerabilities unpatched indefinitely.

What Is Managed Patch Management?

Patch management is the process of identifying, assessing, installing and monitoring software updates across computers and other devices.

Rather than leaving individual employees responsible for updating their own computers, a managed approach allows businesses to maintain greater control over the process.

Effective patch management typically involves:

• Monitoring devices for missing updates.
• Checking updates for known issues or compatibility concerns.
• Prioritising important security patches.
• Deploying approved updates remotely.
• Scheduling installations to minimise disruption.
• Checking whether updates have installed successfully.

This approach is particularly beneficial for businesses with multiple computers, remote workers or employees who don't have the time or technical knowledge to manage updates themselves.

It also helps identify devices that may have missed an important update because they were switched off, disconnected or experienced an installation error.

The Benefits of Including Update Management in Cyber Security

Computer updates should not be treated as an occasional maintenance task. They are an important part of a business's wider cyber security strategy.

Managing updates alongside other security measures offers several benefits.

Reduced security exposure: Important vulnerabilities can be addressed promptly instead of remaining unpatched for weeks or months.

Fewer unexpected disruptions: Checking for known problems and managing deployment schedules helps reduce the risk of problematic updates affecting multiple computers simultaneously.



Greater visibility: Monitoring helps identify computers that have missed updates or experienced installation failures.

Less responsibility for employees: Staff can concentrate on their work rather than deciding which updates are necessary or whether they have installed correctly.

More consistent protection: A managed process helps ensure computers receive appropriate attention, rather than relying on individual users to remember to install updates.

By making patch management part of a wider cyber security service, businesses can take a more consistent and proactive approach to protecting their computers.

How CED Technology Manages Your Computer Updates

At CED Technology, remote monitoring and update management form part of our Cyber Security services.

Using our remote monitoring and management platform, we help keep your Windows computers updated without requiring someone to visit your premises.

Our managed approach includes:

• Remote monitoring: Identifying missing Windows and supported software updates.
• Update assessment: Reviewing available information about known problems before approving updates for deployment.
• Security prioritisation: Ensuring important security updates receive appropriate attention.
• Remote installation: Deploying approved updates without needing physical access to your computers.
• Scheduled updates: Managing installation times to reduce interruptions where possible.
• Update monitoring: Checking deployment status and identifying updates that fail to install.

Although no update can be guaranteed completely problem-free, managing the process helps reduce the risks associated with installing updates indiscriminately or ignoring them altogether.

We take responsibility for managing the update process, so you can concentrate on running your business.

Keep Your Business Protected With CED Technology

Ignoring computer updates can leave your business exposed to unnecessary security risks, while installing updates without checking for known problems can sometimes cause disruption.

The best approach is to keep computers updated through a properly managed process that balances security, performance and reliability.

At CED Technology, we include remote monitoring and update management as part of our Cyber Security services, helping businesses across Cheshire and throughout the UK maintain secure and reliable computers.
