Android Google Play Services has a feature that allows you to opt-out of Ad personalisation. This will instruct apps not to use your advertising ID to build profiles or show you interest-based ads.

You have the option to opt out of receiving interest-based ads as well as reset your advertising ID. Please note, that you will still see ads, but they may not be based on your interests. Also, if you clear your device cache, you will lose your opt-out setting.

How to manage the Google Updater for MacOS


If you’ve download and installed Chrome (or any other Google apps) on your MacOS*, you might not be aware of the Google Updater. This calls home on a regular basis and is designed to download Google Chrome updates in the background, without notifying you. Every time software that is updated should always ask for user consent, but this Updater doesn’t do that. But it should and here is why.

The EU General Data Protection Regulation (GDPR) which comes into force in May 2018, will be the primary law regulating how companies protect EU citizens’ personal data. Under this law, users will generally have stronger rights when processing is based on consent i.e. the right to erase and the right to data portability. If consent isn’t applied, substantial fines are applicable under the GDPR. Google should take note.

How to identify your Windows 10 build and version


Windows 10 build numbers are now very important. Previously Microsoft has always used build numbers, as they represented significant updates to Windows. You may know Windows as Windows Vista, 7,8 etc which also included service packs i.e. Windows 7 Service Pack 1. With Windows 10, this has changed.

Microsoft claim there will be no more versions (and service packs) of Windows, so Windows 10 is what it will be known as for the foreseeable. They are now only releasing two major builds per year. So, how do you find out what build version of Windows 10 you have? This can be found in the Settings App with either of the following options:

  • Hit Windows+I to open Settings > then go to > System > About (scroll down). You will see the Edition, Version, OS Build and System Type.
  • You can also use the Winver Dialog tool – From Start, type “winver” press Enter into the Run dialog. Note: This version does not show whether you are using a 64-bit or 32-bit version of Windows 10. Personally, I prefer option 1.

Useful tip: The version number is in the form YYMM – so if your Windows 10 version number is 1607 this means the 7th month of 2016.
