Windows Defender Security Center for Windows 10 OS
Advantages
  • Windows Defender is baked into Windows 10 OS with Antivirus and Malware Protection. All users are protected out of the box.
    • Independent testing sites indicated WD has a very low FP rate
  • Controlled Folder Access to restrict applications from modifying (ie. creating, deleting, encrypting) the contents of your personal files.
    • By default, both public and private user folders (ie. Documents, Pictures, Videos, Music, Desktop and Favorites) are protected.
    • Additional folders can be protected.
    • Users can add exceptions to trust an application to access the restricted folders.
  • Microsoft Store, Edge browser and the Desktop environment are additionally protected by Smartscreen (Application Reputation)
    • An active Internet connection is required for ideal results.
  • Exploit protection now included which provides a configurable interface for Windows 10's finer security.
    • By default, it's configured for most people's need
    • Technical knowledge required to understand and configure
  • Windows automatically monitors Windows Updates, Storage, Drivers and Battery life for potential issues
  • Windows Firewall is compatible with third-party security and has been proven to be effective for most users.
    • Advanced settings available for user-defined rules.
  • Available Parental controls for Family accounts
Disadvantages
  • Latest features require latest OS stable builds
  • PUA/PUP detection not enabled by default or configurable from Interface
  • Older hardware may experience a negative performance impact by running Windows Defender (ie. slower removal of threats, installing updates, scanning times)
  • Device & Storage Encryption not a standard feature (ie. Windows 10 Home)
  • Lacking an improved File & System Backup system that's comparable with existing third-party solutions, and one that is independent of OneDrive.
  • Currently no Fluent-design UI (as of Sept. 2017) and some "features" misplaced under other places.

Recommendations for Windows 10 in 2018:
  • Primary disk should be a SSD
  • Core i5 or equivalent (any of most recent gens.)
  • At least 8GB DDR3/3L/4 of RAM
  • Unlimited bandwidth Internet connection
