Windows 10: How do I Check the option "Unknown Sources" in my Windows PC Setting to enable downloading...

Hi,

How do I check the option "Unknown Source" in my Windows PC Setting to enable downloading of Google Play App alongwith APK?? I don't see this option anywhere in Setting.

:)

 

HyperSLI (Enabling SLI on non-sli motherboards)

To turn off windows updates in windows 7 follow these steps:

Click the start button, in the search box type in 'windows updates', click on 'windows update'
in the search results list, in the left side of the windows update window click 'change settings'
then in the option bar select 'Never check for updates'.

 

'unknown Sources'?

I have purchased the Nokia Lumia and want to download the Paddy Power app but it says that first I must turn on the unknown sources in the security settings? From what I can see there is no security settings on this phone? I have checked the settings and
found nothing? Is there anyone who knows how to fix this please?

thanks in advance
