Mar 25, 2019 Is PBR image protection is on or off after upgrading from Windows 7 to Windows 8.1 or from Windows 8.1 to Windows 10? How to turn on the PBR Image for Windows 10? You will find answers here: Typically, in Windows 8.1 and 10, the PBR Image protection is OFF, you could turn on the protection settings of PBR Image drive as below: 1. For Windows the PBR loads an additional 16 sectors from the beginning of the partition. These sectors constitute the first stage of the Windows boot loader which in turn loads one of two files depending on the version of Window: For versions of Windows up to XP, the file NTLDR is loaded into memory. PBR then transfers to NTLDR. Jun 13, 2016 This site uses cookies for analytics, personalized content and ads. By continuing to browse this site, you agree to this use.

This topic is intended for original equipment manufacturers (OEMs) who want to add push-button reset features to their Windows 10 desktop computer manufacturing processes.
What Is Pbr Image (y:) In Windows 10
Push-button reset is a recovery tool that repairs the OS while preserving data and important customizations. It reduces the need for custom recovery applications by providing users with more recovery options and the ability to fix their own PCs with confidence.
Push-button reset is included in Windows 10 for desktop editions (Home, Pro, Enterprise, and Education), and was introduced in Windows 8.
What's new for Windows 10
In Windows 10, version 2004, Push-button reset has been updated to include the following change:
- Cloud download is a new option for users to download Windows instead of using the existing installation to perform the reset. This can decrease the overall time it takes to reset if using high speed internet.
In Windows 10, version 1903, Push-button reset has been updated to include the following change:
- Preinstalled apps is a new option under Keep my files which does not apply any customizations from the PC manufacturer. This includes auto-apply folders, applications, and extensibility points.
Previous versions of Windows 10 provided the following improvements to push-button reset:
![Image Image](https://img2.cgtrader.com/items/663335/eda0f3f2a5/large/customizable-webcam-cover-3d-model-obj-stl.png)
- Auto-apply folders make Push-button reset customization easier. Placing customizations and their related asset files in predetermined folders ensures they are restored when a device is reset. This method of configuring Push-button reset can be used instead of the legacy method that used custom scripts and extensibility points.
- Preinstalled apps get restored to an updated state. If a preinstalled app has been updated after installation, it will be restored in its updated state.
- Use default config files when using ScanState to capture customizations: Starting with Windows 10 Version 1703, you have to use the
/config
option with ScanState when capturing customizations. Use only one of the default configuration files included with the Assessment and Deployment Kit (ADK). These files are:- Config_AppsAndSettings.xml – Use this configuration file to specify that both desktop applications and OS settings should be captured by the ScanState tool.
- Config_AppsOnly.xml – Use this configuration file to specify that only desktop applications should be captured by the ScanState tool. Since desktop applications are not always well-defined, this configuration file does not guarantee that all setting related to desktop applications are captured.
- Config_SettingsOnly.xml – Use this configuration file to specify that only OS settings should be captured by the ScanState tool.You can modify these configuration files by setting the migrate attribute for specific components to no, but components that are already excluded from capture/migration in the default configuration files must remain excluded.
- Improved reliability: When you start push-button reset features from the Settings app, Windows scans the system files in the Windows Component Store for corruptions. If it finds corrupt files and can download replacements through Windows Update, it fixes the problem automatically. Although this increases the overall recovery time, it improves the reliability of the PC.
- Recover from failed resets: In Windows 10, versions 1507 and 1511, failures that occur during Reset this PC almost always rendered the PC unbootable/unrecoverable. This feature has been redesigned in the Anniversary Update to support limited rollback if a problem occurs while the PC is in Windows RE.
- Recovery options when booted from recovery media: When the PC is booted from recovery media, the Keep my files and Remove everything features are no longer supported. The only Push-button reset feature available when booted from media is bare metal recovery (i.e. Recover from a drive).
- Image-less recovery: Push-button reset no longer require or support a separate recovery image on a local partition or on media. This significantly reduces the disk space needed to support the features, and makes recovery possible even on devices with limited storage capacity.
- Recovers to an updated state: Push-button reset features now recover the Operating System (OS) and drivers (including device applets that are installed as part of INF-based driver packages) to an updated state. This reduces the amount of time users have to spend reinstalling the OS updates and drivers after performing a recovery.
The Push-button reset user experience continues to offer customization opportunities. Manufacturers use Auto-apply folder; or insert custom scripts, install applications or preserve additional data at available extensibility points.
The following Push-button reset features are available to users with Windows 10 PCs and devices:
- Keep my files Fixes software problems by reinstalling the OS while preserving the user data, user accounts, and important settings. All other preinstalled customizations are restored to their factory state. In Windows 10, this feature no longer preserves user-acquired Windows apps.
- Remove everything Prepares the PC for recycling or for transfer of ownership by reinstalling the OS, removing all user accounts and contents (e.g. data, Windows desktop applications, and Universal Windows apps), and restoring preinstalled customizations to their factory state.
- Bare metal recovery Restores the default or preconfigured partition layout on the system disk, and reinstalls the OS and preinstalled customizations from external media.

Technologies used by push-button reset | Windows Recovery Environment | Windows PE (WinPE) | ScanState |
Windows Recovery Environment (WinRE) is a recovery environment that can repair common causes of unbootable operating systems. WinRE is based on Windows Preinstallation Environment (Windows PE), and can be customized with additional drivers, languages, Windows PE Optional Components, and other troubleshooting and diagnostic tools. By default, WinRE is preloaded into the Windows 10 for desktop editions (Home, Pro, Enterprise, and Education) and Windows Server 2016 installations.
What's new with WinRE for Windows 10?
- By default, if you install Windows using media created from Windows Imaging and Configuration Designer (ICD), you'll get a dedicated WinRE tools partition on both UEFI and BIOS-based devices, located immediately after the Windows partition. This allows Windows to replace and resize the partition as needed. (If you install Windows by using Windows Setup, you'll get the same partition layout that you did in Windows 8.1.)
- If you add a custom tool to the WinRE boot options menu, it can only use optional components that are already in the default WinRE tools. For example, if you have a app from Windows 8 that depended on the .NET optional components, you'll need to rewrite the app for Windows 10.
- If you add a custom tool to the WinRE boot options menu, it must be placed in the SourcesRecoveryTools folder so that it can continue to work after future WinRE upgrades.
- When adding languages to the push-button reset tools, you'll now need to add the WinPE-HTA optional component.
Tools
WinRE includes these tools:
Windows 10 X86
- Automatic repair and other troubleshooting tools. For more info, see Windows RE Troubleshooting Features.
- Push-button reset (Windows 10 for desktop editions , Windows 8.1 and Windows 8 only). This tool enables your users to repair their own PCs quickly while preserving their data and important customizations, without having to back up data in advance. For more info, see Push-Button Reset Overview.
- System image recovery (Windows Server 2016, Windows Server 2012 R2 and Windows Server 2012 only). This tool restores the entire hard drive. For more info, see Recover the Operating System or Full Server.
In addition, you can create your own custom recovery solution by using the Windows Imaging API, or by using the Deployment Image Servicing and Management (DISM) API. Varuthapadatha valibar sangam full movie for mobile.
Entry points into WinRE
Your users can access WinRE features through the Boot Options menu, which can be launched from Windows in a few different ways:
- From the login screen, click Shutdown, then hold down the Shift key while selecting Restart.
- In Windows 10, select Start > Settings > Update & security > Recovery > under Advanced Startup, click Restart now.
- Boot to recovery media.
- Use a hardware recovery button (or button combination) configured by the OEM.
After any of these actions is performed, all user sessions are signed off and the Boot Options menu is displayed. If your users select a WinRE feature from this menu, the PC restarts into WinRE and the selected feature is launched.
WinRE starts automatically after detecting the following issues:
- Two consecutive failed attempts to start Windows.
- Two consecutive unexpected shutdowns that occur within two minutes of boot completion.
- Two consecutive system reboots within two minutes of boot completion.
- A Secure Boot error (except for issues related to Bootmgr.efi).
- A BitLocker error on touch-only devices.
Boot options menu
This menu enables your users to perform these actions:
- Start recovery, troubleshooting, and diagnostic tools.
- Boot from a device (UEFI only).
- Access the Firmware menu (UEFI only).
- Choose which operating system to boot, if multiple operating systems are installed on the PC.
Note
You can add one custom tool to the Boot options menu. Otherwise, these menus can't be further customized. For more info, see Add a Custom Tool to the Windows RE Boot Options Menu.
Security considerations
When working with WinRE, be aware of these security considerations:
- If users open the Boot options menu from Windows and select a WinRE tool, they must provide the user name and password of a local user account with administrator rights.
- By default, networking is disabled in WinRE. You can turn on networking when you need it. For better security, disable networking when you don't need connectivity.
Customizing WinRE
You can customize WinRE by adding packages (Windows PE Optional Components), languages, drivers, and custom diagnostic or troubleshooting tools. The base WinRE image includes these Windows PE Optional Components:
- Microsoft-Windows-Foundation-Package
- WinPE-EnhancedStorage
- WinPE-Rejuv
- WinPE-Scripting
- WinPE-SecureStartup
- WinPE-Setup
- WinPE-SRT
- WinPE-WDS-Tools
- WinPE-WMI
- WinPE-StorageWMI-Package (added to the base image in Windows 8.1 and Windows Server 2012 R2)
- WinPE-HTA (added to the base image in Windows 10)
Note The number of packages, languages, and drivers is limited by the amount of memory available on the PC. For performance reasons, minimize the number of languages, drivers, and tools that you add to the image.
Hard drive partitions
When you install Windows by using Windows Setup, WinRE is configured like this:
- During Windows Setup, Windows prepares the hard drive partitions to support WinRE.
- Windows initially places the WinRE image file (winre.wim) in the Windows partition, in the WindowsSystem32Recovery folder.Before delivering the PC to your customer, you can modify or replace the WinRE image file to include additional languages, drivers, or packages.
- During the specialize configuration pass, the WinRE image file is copied into the recovery tools partition, so that the device can boot to the recovery tools even if there's a problem with the Windows partition.
When you deploy Windows by applying images, you must manually configure the hard drive partitions. When WinRE is installed on a hard drive, the partition must be formatted as NTFS.
Add the baseline WinRE tools image (winre.wim) to a separate partition from the Windows and data partitions. This enables your users to use WinRE even if the Windows partition is encrypted with Windows BitLocker Drive Encryption. It also prevents your users from accidentally modifying or removing the WinRE tools.
Store the recovery tools in a dedicated partition, directly after the Windows partition. This way, if future updates require a larger recovery partition, Windows will be able to handle it more efficiently by adjusting the Windows and recovery partition sizes, rather than having to create a new recovery partition size while the old one remains in place.

Memory requirements
In order to boot Windows RE directly from memory (also known as RAM disk boot), a contiguous portion of physical memory (RAM) which can hold the entire Windows RE image (winre.wim) must be available. To optimize memory use, manufacturers should ensure that their firmware reserves memory locations either at the beginning or at the end of the physical memory address space.
Updating the on-disk Windows Recovery Environment
In Windows 10, the on-disk copy of Windows RE can be serviced as part of rollup updates for the OS. Not all rollup updates will service Windows RE.
Unlike the normal OS update process, updates for Windows RE do not directly serviced the on-disk Windows RE image (winre.wim). Instead, a newer version of the Windows RE image replaces the existing one, with the following contents being injected or migrated into the new image:
- Boot critical and input device drivers from the full OS environment are added to the new Windows RE image.
- Windows RE customizations under SourcesRecovery of the mounted winre.wim are migrated to the new image.
The following contents from the existing Windows RE image are not migrated to the new image:
- Drivers which are in the existing Windows RE image but not in the full OS environment
- Windows PE optional components which are not part of the default Windows RE image
- Language packs for Windows PE and optional components
The Windows RE update process makes every effort to reuse the existing Windows RE partition without any modification. However, in some rare situations where the new Windows RE image (along with the migrated/injected contents) does not fit in the existing Windows RE partition, the update process will behave as follows:
- If the existing Windows RE partition is located immediately after the Windows partition, the Windows partition will be shrunk and space will be added to the Windows RE partition. The new Windows RE image will be installed onto the expanded Windows RE partition.
- If the existing Windows RE partition is not located immediately after the Windows partition, the Windows partition will be shrunk and a new Windows RE partition will be created. The new Windows RE image will be installed onto this new Windows RE partition. The existing Windows RE partition will be orphaned.
- If the existing Windows RE partition cannot be reused and the Windows partition cannot successfully be shrunk, the new Windows RE image will be installed onto the Windows partition. The existing Windows RE partition will be orphaned.
Important To ensure that your customizations continue to work after Windows RE has been updated, they must not depend on functionalities provided by Windows PE optional components which are not in the default Windows RE image (e.g. WinPE-NetFX). To facilitate development of Windows RE customizations, the WinPE-HTA optional component has been added to the default Windows RE image in Windows 10.
Note The new Windows RE image deployed as part of the rollup update contains language resources only for the system default language, even if the existing Windows RE image contains resources for multiple languages. On most PCs, the system default language is the language selected at the time of OOBE.
Known Issue
If the GPO 'Windows Settings/Security Settings/Local Policies/Security Options/Accounts: Block Microsoft accounts' is set to enable the policy 'User can’t add or log with Microsoft account', attempting to restore the System in WinRE will fail with the error message 'You need to sign in as an administrator to continue, but there aren't any administrator accounts on this PC.'
This is a known issue and the workaround is to either avoid setting the 'Accounts: Block Microsoft accounts' to 'User can't add or log with Microsoft Account' or set the MDM policy Security/RecoveryEnvironmentAuthentication to 2.
