There are a lot of “Free” software solutions to solve your problems out there. Ranging from Anti-Virus to Uninstallers and even productivity tools like office suites. These can be very useful but sometimes come with a catch. They install additional software which you do not want or need. This is not uncommon for free stuff to have a gotcha in the form of advertising for other people. But it can be annoying and sometime even dangerous in the case of malware.
Microsoft has a solution that can help curb this practice and it is built into Windows 10. While not perfect, it will stop most third party junk-ware from installing.
You will need to manually activate it with Power Shell (built into Windows also). To do this you will need to open Power Shell as an administrator. Once it is open you will need to type in the following:
Set-MpPreference -PUAProtection 1
After that you can exit Power Shell and that’s it!
This is not a 100% solution so, as always, be careful when installing freeware or any software for that matter.
