 Currently, you can enable [Automatic guest VM patching](../virtual-machines/automatic-vm-guest-patching.md) (Autopatch) by setting the patch mode to **Azure-orchestrated**/**AutomaticByPlatform** on Azure portal/REST API respectively, where patches are automatically applied during off-peak hours.
 
-For customizing control over your patch installation, you can use [schedule patching](updates-maintenance-schedules.md#scheduled-patching) to define your maintenance window. You can enable [schedule patching](scheduled-patching.md#schedule-recurring-updates-on-single-vm) by setting the patch mode to **Azure orchestrated**/**AutomaticByPlatform** and attaching a schedule to the Azure VM. To patch your machines, the VM ARM properties to differentiate between **schedule patching** or **Automatic guest VM patching** were the same as the patch mode in both cases is set to *Azure-Orchestrated*.

So, the VM properties couldn't be differentiated between **schedule patching** or **Automatic guest VM patching** as both had the patch mode set to *Azure-Orchestrated*. 
 
-So, in some instances, when you remove the schedule from a VM, there is a possibility that the VM may be auto patched for critical or security patches and subsequently rebooted. To avoid such accidental or unintentional patching, a new prerequisite has been introduced - **ByPassPlatformSafetyChecksOnUserSchedule**, when set to *true* accurately determines the VMs for scheduled patching and ensures that the VMs with this property set to *true* will no longer be patched as a path of the Automatic VM Guest Patching schedule when the VMs do not have an associated maintenance configuration.
+Additionally, in some instances, when you remove the schedule from a VM, there is a possibility that the VM may be auto patched and rebooted. To overcome the limitations, we have introduced a new prerequisite - **ByPassPlatformSafetyChecksOnUserSchedule**, which can now be set to *true* to identify a VM using schedule patching. It means that VMs with this property set to *true* will no longer be auto patched when the VMs don't have an associated maintenance configuration.

 > For a continued scheduled patching experience, you must ensure that the new VM property, *BypassPlatformSafetyChecksOnUserSchedule*, is enabled on all your Azure VMs (existing or new) that have schedules attached to them **before May 19, 2023**. This setting will ensure machines are patched using your configured schedules and not autopatched. Failing to enable the pre-requisite will give an error that the prerequisites aren't met.

 You can use update management center (preview) in Azure to create and save recurring deployment schedules. You can create a schedule on a daily, weekly or hourly cadence, specify the machines that must be updated as part of the schedule, and the updates to be installed. This schedule will then automatically install the updates as per the created schedule for single VM and at scale.
