Block Windows 10 – Zip file


Windows 10 trying to force upgrade. System and software may not be compatible with Windows 10.


Windows 10 logo appears in bottom right corner of the screen. Messages now state that machine is on a countdown to automatically update.


Download the attached zip file, and unzip batch file to your desktop. Right click file and select ‘Run as Administrator’, the machine will now restart  This will remove the notification and block the associated windows update.

NB: If the upgrade has already started then this solution may fail. If the upgrade fails then it should revert back. If the upgrade goes through then you will need to revert system back.

A kernal extension corruption


To do the following you’ll have to connect to your WiFi network….

Hold the ‘Option’ (Left Alt) key down and then click on the Apple logo in the top left of your screen.

Click on System Information, and in the left hand navigation window scroll down to Software (click on the triangle to expand it, it you have to), and then click on Installations.

It should be in alphabetical order, but if not then click on the Software Name in the right hand window. Scroll down till you find ‘Incompatible Kernal Extension Configuration Data’. There will probably be three listings from different dates. The last one should be version 3.28.2 and have a date from the 28th February onwards. If you have version 3.28.1 then you will need to update to the latest 3.28.2

Open Terminal (which is in Applications > Utilities)

Then type in the following command below exactly as you see it, followed by your admin password. You won’t see your password as it is permanently hidden, so don’t worry.

sudo softwareupdate –background

Quit Terminal and restart your computer.


Another way is to boot to Recovery Console, by holding Cmd R when booting the computer and then reinstalling your OS. The Terminal route is quicker and assumes you have access to a WiFi network to get your Ethernet working again.

Restart the machine and then Safari.


On an iOS device…..

Go into Settings > Safari > and turn off the toggle for ‘Safari Suggestions’, then restart the device.

[Leave a comment]

Plantronics MX22Problem

Either the caller or listener can hear an echo when a call is in progress.


This can be caused due to an incorrect setting on the Plantronics MX22 amplifier.


If you hear an echo please try the following solutions:

  1. If your phone’s volume is currently set to a higher setting than medium try lowering it to medium.
  2. If the listening volume is currently too low try increasing the volume on the amplifier. 
  3. If the listening volume is still too low try increasing the volume on the headset.
  4. If the echo persists try lowering the speaking volume on the amplifier via the side dial.
  5. If your speaking volume is too low for your listener to hear in this position, adjust the position of the headset to ensure the microphone is two finger’s width from the corner of your mouth.

If your callers can hear an echo please try the following solution:

Try adjusting the configuration switch between each setting, The most commonly used position we find is setting 5.
