In today's article, we will discuss the safety of disabling Windows Security. This program provides a wide range of security features, including real-time protection, cloud file scanning, communication protection, and much more. Disabling this program means losing these features and exposing your computer to risks.

However, there may be exceptional cases that require temporarily disabling the program, such as downloading a file from the internet mistakenly classified as harmful.

When considering permanently deactivating Windows Security, it requires careful consideration. If you install a protection program compatible with the Windows operating system and works without issues, Windows Security will automatically disable itself. However, if the protection program is incompatible, you will need to manually disable Windows Security permanently. Be aware that using more than one protection program at the same time can impose a significant burden on computer resources and performance.
