Thank you for the update!
My apologies about not asking before, but I have noticed that you only have 8GB of RAM. For Windows 11, 8 GB of RAM is generally considered the minimum for basic tasks, such as web browsing, document editing, and media consumption. However, if you use memory-intensive applications (like gaming, photo/video editing, or running multiple programs simultaneously), 8 GB may start to feel insufficient.
Windows 11 itself uses more memory than previous versions, and modern applications, particularly web browsers like Chrome or Edge, can also consume a large portion of your RAM. This is especially true if you keep multiple tabs open. Additionally, background processes and startup programs can significantly contribute to high memory usage.
Since you're experiencing high memory usage (65-70% when idle), your system is already pushing the limits of the installed RAM. When opening additional applications, it's likely why you see the memory usage quickly escalate to 80-85%. This indicates that upgrading to at least 16 GB of RAM would be beneficial. Doing so would not only provide a smoother experience but also ensure that your system can handle more demanding tasks and multitasking without running into performance issues.
But, for now while you're still not upgrading, we can increase your Virtual Memory.
Right-click on ‘This PC’ and select ‘Properties.’
Click on ‘Advanced system settings.’
Under the ‘Advanced’ tab, click ‘Settings’ under the ‘Performance’ section.
Go to the ‘Advanced’ tab and click ‘Change’ under ‘Virtual memory.’
Uncheck ‘Automatically manage paging file size for all drives.’
Select the drive (usually C:), choose ‘Custom size,’ and set the initial size to 1.5 times your RAM (12,000 MB) and the maximum size to 3 times your RAM (24,000 MB).
Click ‘Set,’ then ‘OK,’ and restart your computer.
Please let me know if you have any more questions, I'll do my best to respond as soon as possible.
