No more optimizers and registry cleaners: As of March 1, 2018, Windows Defender and more products της Microsoft θα ξεκινήσουν να καταργούν προγράμματα που πιέσουν τον χρήστη να αγοράσει λογισμικό. Σε αυτά συμπεριλαμβάνονται προγράμματα καθαρισμού μητρώου και βελτιστοποιητές συστήματος (registry cleaners και optimizers) που προσφέρουν δωρεάν σαρώσεις, ανιχνεύουν προβλήματα και προβάλλουν ανησυχητικά messages, asking the user to buy some product that can fix everything (everything).
In order to prepare developers for this change, Microsoft updated the evaluation criteria of behaviors that will no longer be acceptable.
Programs should not display alarms or messages that force the user with deceptive content to pay for additional services or to gain access to unnecessary features.
Software that forces users may display the following features, including:
Report errors about the user's system in an excessive or alarming manner, and require payment to resolve errors or to perform other actions, such as conducting research, downloading a file, subscribing to a newsletter, etc.
Indicate that no other action can correct the reported bugs or issues
Require the user to act within a limited period of time to resolve an alleged issue
This particular move is a very important step, as these types of products have been around for a long time problem, especially for users who have no experience with computers.
Worrying messages that indicate threats and errors, cause fear in users and often force them to buy products that they immediately realize do not solve the problems. 
Often, suppliers of system optimizers and registry cleaners release the same application under many different names. This allows them to keep pushing for the same product when end users find that the previous one did not work as expected.
With the release of these new criteria, companies will have to comply otherwise their software will be removed from Windows. Developers who develop these types of programs can submit their software to Microsoft for validation using Windows Defender Security Intelligence company portal.
Microsoft will evaluate the program and determine if the program will continue to run on Windows or will be removed on March 1.
