Windows 11 allows apps to run in the background, which is convenient, but it can lead to excessive CPU usage.Hardware requirements

Processor: 1 gigahertz (GHz) or faster with two or more cores on a compatible 64-bit processor or system on a chip (SoC). Memory: 4 gigabytes (GB) or greater. Storage: 64 GB or greater available disk space.That is not the case with Windows 11, which prioritizes foreground apps and has fewer default background processes consuming resources. As a result, if your PC has less RAM and CPU power, Windows 11 will enable better performance.

Is Windows 11 better than 10 : Both operating systems have similar security features, update processes, and compatibility with hardware and software. However, Windows 11 offers improved performance and features compared to Windows 10, making it a better choice for those looking for a more modern and efficient operating system.

Does Windows 11 slow down CPU

“To put it simple [sic], every CPU benchmark shows significantly reduced CPU performance after updating to Windows 11 23H2 from 22H2, even after a fresh/clean install.

Why is my CPU always 100% : Outdated device drivers and other apps can become buggy and even incompatible with current versions of Windows 11. These issues can push your PC up to 100% CPU usage, or even lead to crashes and freezes. Updating your drivers and software is a great way to clean up and speed up your PC.

For this reason, Windows 11 is an ideal choice for anyone with a Windows laptop or desktop with lower RAM and CPU power. Some of the most recent updates to Windows 11 also offer quicker wakeup times from sleep mode and boosted speeds for solid-state drives (SSDs).

It is the absolutely minimum required RAM, so you can get Windows 11 install, but if you are going to run apps and other stuff, 4gb will run slow for sure. It is not ideal for performance.

Is Windows 10 or 11 better for performance

Windows 11 is snappier than Windows 10, but the differences are small in real-world use. The various optimizations in Windows 11 help it to run faster on weaker laptops, but you're not giving up a ton of performance with Windows 10.If your system is on the low end of the specifications or doesn't have TPM 2.0, and you're happy with its performance in Windows 10, you may want to avoid the update. If you have a speedy NVMe SSD, a compatible graphics card, and an HDR monitor, your gaming experience will likely improve in Windows 11.Windows 11 scores slightly higher overall in most tests, but occasionally turns in slightly lower results when checking for frames per second (FPS) performance when actually playing some games. In other games, FPS performance is slightly better on Windows 11.

Windows 11 is snappier than Windows 10, but the differences are small in real-world use. The various optimizations in Windows 11 help it to run faster on weaker laptops, but you're not giving up a ton of performance with Windows 10.

Is Windows 11 better for slow PC : Windows 11 includes many visual effects, such as animations and shadow effects. These look great, but they can also use additional system resources and can slow down your PC. This is especially true if you have a PC with a smaller amount of memory (RAM).

Will 100C damage a CPU : I know that an average PC is within 40-60 degree C when in regular use but can go up 80 if running extensive programs. Anything over 90C is a little concerning… going over 100C and you've got a pretty serious issue and could damage your CPU.

How to fix 100% CPU usage in Windows 11

Run a full system scan using antivirus software to check the computer is not infected with malware, which can often cause high CPU usage. Also ensure Windows 11 and all drivers are up to date. Sometimes, outdated drivers or system files can cause compatibility issues leading to high CPU usage.

At a baseline level, Windows 10 and Windows 11 offer a similar level of gaming performance. Benchmark testing shows that identical hardware turns in almost identical results when running Windows 11 versus Windows 10.It's worth noting that while Windows 11 brings visual enhancements and new features, it also requires some additional system resources compared to Windows 10. However, your PC's specifications, including 8GB RAM and an AMD Ryzen 4600H processor, should generally be sufficient to handle Windows 11 smoothly.

Is 16GB RAM OK for Windows 11 : Windows 11 should run smoothly even with 16GB of RAM, as the recommended system requirement for RAM is only 4GB for 64-bit systems. Therefore, it's less likely that the delay you're experiencing is solely due to the 16GB of RAM.
