When you run a small business there are a lot of tasks that you need to keep on top of to ensure your business keeps running. Most businesses rely upon technology such as Windows and know that they release updates on a regular basis, some of which seem to cause us more issues than you get in return.
In this article we discuss why and how to check if Windows is up to date and some of the other systems that you should be updating as part of your IT security.
Why do we update Windows?
Microsoft Windows 10 was released in July 2015. When the operating software is released, it is not always possible to consider every possible usage or security vulnerability that is discovered, hence Microsoft provide software updates and fixes on a regular basis.
Hackers and malware take advantage of the security vulnerabilities so ensuring your devices are updated is a key part of your business’s security.
Did you know that some versions of Windows 10 are not supported by Microsoft?
Windows 10 follows Microsoft’s modern lifecycle policy so only the version 1909 or above is supported by Microsoft. This can mean that a feature pack has not been applied when it was available. The current feature version is 21H1. Each Feature pack is released approximately every 6 months. You can check the current version you are running by searching for About and then choose open
This will display your device specifications and the Windows specifications. Here you can see the feature version you are running.
If you are not running version 1909 or above then you should search for “check for updates.” This should show that a feature pack is available. Microsoft Windows 10 release information

What devices should you update?
Apart from ensuring your PCs and servers are kept updated, you should also update your network devices such as:
- Internet Router
- Network Switches
- Wireless Access point
- Network Attached Storage (NAS)
- Mobile phones
- CCTV cameras
- IOT devices (Amazon Alexa, Google hub)
Most of these devices will have their own software know as firmware that the manufacturer’s will provide updates for. The updates maybe automatic or require manual update. If the Internet router needs to be updated this will require a small amount of downtime; so it could be scheduled for out of hours.
Some devices such as CCTV cameras will provide the potential attacker a method of accessing your network as they will often require open ports on your network firewall. The devices should be checked to ensure only the required ports are enabled. Where possible additional network protection such as vlans configured to prevent access to other systems.
Do you change the devices default credentials?
Most devices come with a default set of login credentials from the manufacturer. These will often be listed in the devices documentation and will therefore be available to any potential attacker.
It is best practice to set up your own and enable 2factor authentication if the device supports it.
You should rename or disable the old admin account
Where possible, ensure a complex password is used – just make a note in case you need to access in the future.
