Windows Security Center reporting 'at-a-glance' issues
The Windows Security Center prompts "clear at a glance" problem is usually not a virus or system crash, but an exception in security settings. 1. Antivirus protection is not enabled: Defender is not restarted after uninstalling the third-party antivirus software. The solution is to manually enable real-time protection or reset Defender; 2. The firewall is turned off: Check the firewall status and ensure it is turned on. If it cannot be changed, you need to check the group policy or registry; 3. Device security is disabled: Turn on virtualization technology in the BIOS and enable kernel isolation; 4. Third-party software interference: Clean up residual processes and ensure that Microsoft security services are set to automatically start. Troubleshooting these settings can solve the problem in most cases.

How to revert to a previous Windows version
The fallback Windows version can be achieved through the system's own functions within 10 days after upgrading. After Windows upgrade, only the old system files are retained for 10 days. If the timeout is over, the system needs to be reinstalled; the fallback path is Settings → System → Recovery → "Roll back to the previous version of Windows", but if the option is gray and unselectable, it may be timeout or insufficient space; if the time window is missed, you can use system mirroring, installing the old system with the USB flash drive, etc. to recover, but the operation is complicated and there is a risk of data loss; before the fallback, you should ensure that the power is stable, backup the data, turn off the antivirus software, and check the driver compatibility.

Persistent disk usage at 100% on Windows
PersistentDiskUsage100% is not an error, but if the system slows down, you need to troubleshoot. It is a Windows background optimization mechanism that uses idle time to perform indexing, maintenance and other tasks. If the "activity time" is high and the response is slow, the program opening is slow, the mouse is stuck, etc., it may affect the front-end use. Solutions include: 1. Pause or adjust the "WindowsSearch" service to reduce disk occupation; 2. Close the "automatic maintenance" task, modify the registry and be suitable for advanced users; 3. Identify and end highly occupant processes such as WindowsDefender, SearchIndexer.exe, etc. through the resource monitor; 4. Update hard drives and system patches, especially

Windows Disk Management showing unallocated space
There is no need to worry about seeing "unallocated space". It is an area on the hard disk that has not been partitioned. It may be displayed as a black disk-free area due to deleting partitions or installing the system without fully utilizing the hard disk; to use it, you can 1. Expand adjacent partitions (right-click adjacent partitions → "Extended volumes", only NTFS partitions and need to be adjacent), 2. Create a new independent partition (right-click unallocated space → "New Simple Volume", set size and format); if it cannot be operated, it may be because the disk is not the same, the expansion location is limited, or the MBR partition has reached the upper limit, and it can be converted to GPT or use a third-party tool to solve the problem. It is recommended to back up data before operation. Avoid using the command line when you are not familiar with it, or it can not process it for the time being and will not affect the system operation.
