High CPU consumption detected for Windows 11 antimalware service executable.
High CPU consumption detected for Windows 11 antimalware service executable.
It looks like the program is consuming a lot of system resources, especially when you interact with your PC. For an i3-1005G1, this could be normal depending on the workload, but it might be worth checking for background processes or optimizing startup settings.
It's understandable to be puzzled by the performance differences. On Windows 11, the CPU tends to stay at full capacity most of the time, whereas Linux distributions often use it more efficiently, especially during compilation tasks. Windows Defender Antivirus can also consume significant processing power. The reason Windows 11 feels sluggish can come from these factors combined.
Great to hear! I’ll check it out and compare it to my Linux setup. I’m currently using Manjaro and noticed a nearly double speed improvement.
I actually own a Dell XPS 13 equipped with a 1065g7 processor and I managed to get through Windows 11—though it wasn’t perfect. The performance is noticeably slower, battery drains faster, and the system tends to overheat constantly. Some might say I’m just seeing things, but after reinstalling Windows, everything feels much smoother. Even with a clean install of Windows 11 (I’ve tried several times), my laptop still struggles to run well, even though Dell claims it’s compatible. Things like Word seem to cause problems, making it difficult to use.
I have a slower processor and a system with 6GB of RAM. I’m not experiencing this problem. It seems like Defender is performing a full system check and something is interfering during use. Run a complete Windows Defender scan. (Ensure it stays active while scanning.) After that, navigate to Start, type "Maintenance," and select the Security & Maintenance panel. Click on the "Start maintaining" link in the expanded section. Let it run its course. It may take some time. Once finished, go to "Change maintenance settings" and pick a suitable time—2 AM is the default—but make sure your system is powered on. If it can’t wake from sleep or hibernation, adjust the schedule accordingly. If the issue persists, modify Windows Defender’s task scheduling: open Task Scheduler, go to the left sidebar, select Microsoft > Windows > Windows Defender, and double-click "Windows Defender Scheduled Scan." Adjust settings as needed. Remember, if your system remains unresponsive, it may revert to its current state.
I've tried this before and the best way seems to be turning off real-time protection, which actually undermines its purpose. This issue also occurs after a fresh Windows 11 setup.
