Hi, I'm Bernard, a fellow Windows user. I'm happy to help!
I understand the issue you're experiencing. Older operating systems like Windows XP and Windows 7 may feel faster depending on the computer because they are lighter and have fewer features at the time.
In contrast, Windows 11 requires higher hardware specifications to ensure full compatibility and proper functionality. This is because it includes more features, built-in applications, and stronger security measures.
Modern operating systems prioritize security due to the increasing number of malware and cyber threats. As a result, Windows 11 is designed with higher security standards, which also require more powerful hardware.
Additionally, many applications running on Windows 11 are more demanding due to their advanced functionality and compatibility requirements with third-party software.
Just to confirm, may I know the PC specification you have? In addition, since you experience system failures, can you please check the System logs on the PC so I can further examine the root cause of the issue?
To share the System logs, please follow the steps in the link below:
Press the Windows key + X, then select "Event Viewer"
Click the drop-down of "Windows logs"
Right-click System > click Filter Current logs > Check: Critical, Warning, and Error > Hit OK
On the right pane, click "Save Filtered Log File As..."
Save the System logs file to your desktop and share it by following the steps from the link:
Note: You can also use your preferred cloud storage to upload and share the logs.
