If you want the deployment to persist, make sure that this check box is selected. By default, this check box is selected, with the exception of the Automatic Deployment Rule Wizard when you select the Definition Updates template for Endpoint Protection. If you do not want to initiate a write filter restart to persist this content, make sure this check box is not selected. When the check box is not selected, you will not initiate a restart, but the deployment will be applied to the overlay at the deadline schedule, or during a configured maintenance window.
The drawback with this choice is that your installation might not persist after a restart. For applications, software updates etc. Obviously, this introduces a delay and there is a further delay because the device must restart each time before the required changes are re-applied to the overlay. The following table provides information about whether Configuration Manager supports an opportunistic persist and a forced persist to manage write filters.
None of these features require or support write filter exceptions. As shown in the previous screenshot, the forced persist option for a software deployment is a check box called Commit changes at deadline or during a maintenance window.
For the Endpoint Protection client setting, it is called For Windows Embedded devices with write filters, commit Endpoint Protection client installation.
Although we need write filters to be disabled so that we can apply required changes, we also want to limit any unwanted writes to the disk while the write filters are disabled. New in Configuration Manager SP1, when Configuration Manager disables write filters, it prevents all users except administrators from logging on to the device. If users try to log on, they see a servicing lock screen when they try to log on to their embedded device. The following screenshot shows what this looks like for Windows Embedded Standard 7.
The world of embedded devices has a wide variety of usage scenarios when it comes to end users, some of which are as follows:. The changes we made in Configuration Manager were to ensure reliable operation for the scenarios where there is no user interaction during management actions, such as software installations.
So what does this mean if you plan to use Windows Embedded to deliver a Thin PC solution to your users? This scenario is supported, but the following user interactions are not available:. Configuration Manager does not support software deployments that have a purpose of Available. If you target a software deployment to an embedded device, it does appear in Software Center but if users try to install it when write filters are enabled, they see an error message that they do not have permissions.
You can interactively install the software when write filters are disabled, but remember that if Configuration Manager disables the write filters as part of another deployment, only administrators can log on to the embedded device. Software Center lets users configure their business hours and select an option to only install software outside their specified business hours.
If we made these options available to users on embedded devices that had write filters disabled, their configuration choices would not persist after a restart. However, note that if the embedded device was imaged when write filters were disabled, and these options were configured, the image would include these settings and users will not be able to change them.
This end result might be suitable for your environment, or it might not. The Desktop Window Manager feature is still present in this release of Windows despite it focusing on older hardware. Windows Thin PC contains write filters which are both file-based and enhanced and can be enabled to prevent users and programs from writing data to the main disk and redirect all data writes to a virtual hard disk that is cleared when the machine reboots to ensure that Windows Thin PC is restored to its original image.
Windows Thin PC also contains some minor enhancements like the ability to suppress certain Windows dialog boxes, a keyboard filter to suppress unwanted keystrokes and support for custom-defined keystroke combinations. Build list legend Available build. Confirmed build. Unconfirmed build. Fake build. Microsoft Windows. Tried to read up on these but didn't find the answer to the above questions. Just writing to post an update on this.
After doing some more research, tria and error, found out the following article from Microsoft. However, if I have to use EWF instead, I think I will still have to go with your suggestion and set the computer to either ignore boot failure or renamed the bootstat. Please confirm if there's any other alternatives for EWF. The content you requested has been removed. Ask a question. Quick access. Search related threads. Remove From My Forums. Asked by:.

I get the Windows Recovery Error prompt and have the following option for boot-up: 1. Start Windows Normally I can start Windows normally with no problem but need to go through this every time the computer is restarted. And, with Write filter disabled, I don't have any issue with the boot up of the OS.
If you need more information, let me know. Wednesday, October 19, PM. NET Step-by-Step. Thursday, October 20, AM. Hi there, Pman, While we're technically not the "support channel" for Thin PC, we understand the product's inner workings, and can offer some advice.
Ddisable the EWF 2. Reboot 3. Open an elevated commmand prompt right-click, run as administrator 4.
