defender有一些计划任务，还有其他一些计划任务（diskcleanup等）冷不丁跑起来可能影响业务，可以自行评估是否要关闭，powershell命令仅供参考：
Get-ScheduledTask -TaskPath "\Microsoft\Windows\Data Integrity Scan\","\Microsoft\Windows\ApplicationData\","\Microsoft\Windows\Defrag\","\Microsoft\Windows\DiskCleanup\","\Microsoft\Windows\DiskDiagnostic\","\Microsoft\Windows\DiskFootprint\","\Microsoft\Windows\Windows Defender\","\Microsoft\Windows\Maintenance\" 2>$null | Disable-ScheduledTask 2>$null
