If you recently made system setting changes or installed a buggy update that caused the computer to stop working, you can still recover Windows 10 using the secret Registry backup. However, there is one caveat, since the operating system no longer creates these backups automatically, you have to re-enable it manually before you can use it.
In this guide , you will learn the steps to restore the previous version of the Registry manually from its automated backup on Windows Start PC with Advanced startup options. Now you need to move to the drive letter where Windows is installed.
Type the following command to enter into the correct drive where Windows 10 is installed and press Enter :. Type the following command to verify you are in the correct drive to restore the Registry and press Enter :. If you see the Windows folder, you are in the correct drive letter.
If the entire boot and system volume are restored at the volume level, this value must not be set. If the LastRestoreId registry value does not exist, the backup application should create it under the following registry key:. The value should be a unique opaque value such as a GUID. Whenever a new system state restore is performed, the backup application should change the data of the LastRestoreId value.
Other applications that need to monitor system state restores should store the data of this registry value. This data can be compared against the current data of the LastRestoreId registry value to determine whether a new system state restore has been performed. The MaxShadowCopies registry value specifies the maximum number of client-accessible shadow copies that can be stored on each volume of the computer. Client-accessible shadow copies are used by Shadow Copies for Shared Folders.
For more information about shadow copies, see the VSS documentation. If the MaxShadowCopies registry value does not exist, the backup application can create it under the following registry key:. The default data for this value is The minimum is 1. The maximum is For other types of shadow copies, there is no registry value that corresponds to MaxShadowCopies. The maximum number of shadow copies is per volume. Windows Server On cluster servers, MaxShadowCopies registry value's data may need to be set to a lower number.
VSS allocates a shadow copy storage area or "diff area" to store data for shadow copies. The minimum size of the shadow copy storage area is a per-computer setting that can be specified by using the MinDiffAreaFileSize registry value. If the MinDiffAreaFileSize registry value does not exist, the backup application can create it under the following registry key:. The data for this key is specified in megabytes.
You should specify a number that is a multiple of If you specify a value that is not a multiple of 32, the next multiple of 32 will be used. Shadow copies might not function correctly if the MinDiffAreaFileSize registry value specifies a minimum size that is larger than the maximum size of the shadow copy storage area. To specify the maximum size of the shadow copy storage area, use the Vssadmin add shadowstorage or the Vssadmin resize shadowstorage command.
To see the current maximum size, use the Vssadmin list shadowstorage command. Just like the older Windows versions, the registry is an essential component of the Windows Vista operating system. If the registry gets damaged due to an accumulation of junk information such as obsolete, incorrect, or malicious registry keys, it can cause severe damage to your Vista computer and even make it inaccessible.
To save yourself from all this trouble, the best safeguard that you can employ is to make regular backups of the registry. Because there is no specific tool in Windows Vista that enables automatic registry backups, you will have to make manual backups of the registry. The Registry Editor tool is primarily used to perform manual edits to the Windows registry.
The tool also provides options that you can use to backup either a small portion or the entire registry tree. To back up the Windows Vista registry using Registry Editor, perform the following steps:.
System Restore is a useful tool that Windows Vista users can use to rollback their computers to last known working condition, in case their system fails. If your system meets certain required specifications, System Restore is enabled by default on your Vista system. The tool works by taking a snapshot of various system files, configuration information, and the registry.
