Windows 11 24H2: How to get the maximum speed out of it

In addition to battery-saving "user-centric CPU power management", enhanced click-to-do functions and improved widget performance, the update also brings new visual effects and system processes. For many users, this means more convenience - but (potentially) less speed.

Where do the performance changes come from?

Windows 11 24H2 has been rolling out successively since June 10, 2025, accompanied by updated driver packages and the special update KB5063060 (Build 26100.4351), which primarily fixes compatibility issues (e.g. with Easy Anti-Cheat). However, forum posts and user comments suggest that Windows 11 24H2 is equipped with new visual effects and background mechanisms, some of which are perceived as more CPU-intensive by users with older systems. However, official measurement data or benchmarks are not yet available.

Users with older systems or weaker GPUs in particular often report noticeable slowdowns when starting the system or switching between windows.

In an era where real-time performance and speed are setting new standards, any slowdown carries significant weight. Whether in live gaming, where milliseconds determine victory or defeat; in instant transfers that manage the flow of funds in real time while playing a game or shopping; on casino platforms with lightning-fast payouts that credit accounts in a matter of moments, or in modern applications like DeepL Voice for Meetings, which provides simultaneous translation in over 60 languages within Microsoft Teams—users expect their systems to respond without delay. These expectations make it clear that operating systems and hardware must work together seamlessly to meet these high standards—even the slightest delays can noticeably disrupt everyday digital life.

After the 24H2 update, some users report that their system seems less "nimble" - especially when booting, switching between windows or with the energy profile. Although the update certainly brings technical innovations - for example, improved power management that automatically switches between efficiency and performance - many of these mechanisms require computing power, which can lead to noticeable delays on older hardware. It is therefore worth making targeted adjustments to three areas:

1. Reduce
   
   Animations & Visual Effects
2. Configure
   
   Performance Mode
3. Perform a Clean Boot & Check
   
   for Unnecessary Services

These approaches ensure that you can enjoy the new features without sacrificing speed.

The best tweaks for more agility

Optimize animations and visual effects

One of the most immediate adjustments you can make after the update is to reduce visual effects. Microsoft itself recommends:
„Turn off Animation Effects“ via Settings → Accessibility → Visual Effects. Users report that their computer seems to run "faster" afterward—especially when switching between desktops or opening menus. For even finer control, you can use SystemPropertiesPerformance.exe to selectively disable individual options under "Visual Effects," such as „Show window contents while moving“ or „Fade effects.“.

Actively set performance profile

Many PC systems are running updates with a balanced energy-saving mode. After 24H2, it is worth setting the energy-saving plan to High Performance or Maximum Performance. This allows you to stay in high performance mode without throttling performance - ideal for smooth reactions under memory load or upscaling. Windows 11 24H2 features a new, intelligent CPU management system that can automate the switch between energy-saving settings. If you still want maximum performance, a manual energy-saving plan makes sense.

Clean Boot & Autostart Optimization

A clean boot after the update ensures that no third-party services throttle performance. Microsoft recommends hiding all Microsoft services in msconfig and manually deactivating all other services. At the same time, it is worth taking a look at the Task Manager under "Autostart" to remove programs that are no longer required from the start.

This approach is especially recommended if you feel like the system is freezing or responding slowly in the background. With a clean boot enabled, Windows usually runs significantly faster and more stably after major updates.

The same speed as before - and more

Used correctly, the optimized settings bring back a lot of speed: animations less annoying, boot faster, UI smoother. You don't have to do without the new features such as click-to-do, widgets or intelligent CPU management - you just learn how to fine-tune them.

Should you nevertheless experience problems such as freezes, incompatibilities with EAC-based games or driver errors in individual cases, a rollback of KB5063060 will help until the next update wave arrives.

Windows 11 24H2 brings noticeable improvements—but also puts more strain on the system. If you want to maintain noticeable speed, you should look at five key areas: visual effects, power management, clean boot, drivers, and—if necessary—rolling back individual updates. With these simple steps, Windows 11 will start up, run, and feel smoother right away—even after the major feature upgrade.
