Detailed Review

O&O Software GmbH in Berlin has been making Windows system software since 1997. Two of its tools matter here. O&O ShutUp10++ is freeware that lays out Windows 10 and 11 telemetry and privacy settings as individual switches with a recommendation for each, and it is still maintained for current Windows 11 builds. O&O Defrag is a defragmentation and drive-optimization tool sold as a permanent licence.

Neither tries to be a one-click optimizer, and that is the point. ShutUp10++ addresses the privacy side of what suites like Advanced SystemCare bundle, and Defrag the disk side, each with more control than a suite gives.

What O&O Software does well

  • O&O ShutUp10++ is free and actively maintained
  • O&O Defrag is a permanent licence
  • Berlin company with a published impressum
  • Clear, per-setting explanations rather than a single "fix" button

Where O&O Software falls short

  • Separate tools rather than one suite
  • Windows only
  • Defragmentation matters little on SSD-only machines

Standout feature. O&O ShutUp10++: a free, maintained, German tool that shows every Windows telemetry setting individually and lets you decide.
