Introduction

With the release of Windows 11 24H2, users are faced with a critical decision: perform a clean installation or opt for an in-place upgrade from version 23H2. This article delves into the performance implications of both methods, providing a comprehensive analysis to guide users in making an informed choice.

Background

Windows 11 24H2 introduces several enhancements aimed at improving system performance and user experience. However, the method of installation can significantly influence the realization of these benefits. A clean install involves erasing the existing system and installing the OS afresh, while an in-place upgrade updates the existing system without removing files or applications.

Performance Analysis

Boot Times

  • Clean Install: Users report boot times as low as 10-12 seconds on high-performance SSDs running Windows 11 24H2, a notable improvement from the 15-18 seconds average boot time experienced on 23H2.
  • In-Place Upgrade: Users experience boot times averaging around 14-16 seconds for Windows 24H2, with some reporting no significant change from their previous installations.

Application Launch Times

  • Clean Install: Benchmarks indicate that applications launch approximately 20-25% faster than the same applications running under 23H2, attributed to improved memory management and optimized CPU scheduling.
  • In-Place Upgrade: Users observe application launch times reduced by about 10-15%, indicating some improvements but not as significant as the clean install scenario.

Gaming Performance

  • Clean Install: Tests with titles like "Call of Duty" and "Cyberpunk 2077" show that clean installs of Windows 11 24H2 achieve frame rates approximately 15-20% higher compared to 23H2, with loading times nearly 30% faster.
  • In-Place Upgrade: Users performing in-place upgrades experience minor improvements—estimated at around 5-10% in frame rates, with loading times occasionally reduced by 15%.

General Responsiveness

  • Clean Install: Benchmarks indicate fluid performance even under multitasking scenarios, with users reporting fewer stutters and a general sense of smoothness while switching between applications.
  • In-Place Upgrade: While improvements are noted, they often result in lower responsiveness than clean installs, with potential lag when switching between resource-heavy applications or performing demanding tasks.

Implications and Recommendations

The choice between a clean install and an in-place upgrade depends on user priorities:

  • For Optimal Performance: A clean install is recommended to fully leverage the performance enhancements of Windows 11 24H2.
  • For Convenience: An in-place upgrade offers a quicker transition with respectable performance gains, suitable for users prioritizing time and ease of upgrade.

Conclusion

Both installation methods have their merits. Users seeking maximum performance benefits should consider a clean install, while those valuing convenience may opt for an in-place upgrade. Staying informed about these options empowers users to make decisions aligned with their computing needs.
