How to restore Windows registry
Any corrupted entries will cause a lot of problems for your operating system. Installing unknown applications, manually editing entries, and malware infections can damage the registry. We recommend that you back up before updates or make substantial changes to your system. You can use some tools built into your computer to do this. You can also use the command line interface to avoid the hassle of navigating through the GUI. In this article we will not only talk about how to backup but also how to restore Windows registry.
To manually restore registry on Windows 10, follow these steps:
X:WindowsSystem32
This means that you will now need to switch to the drive letter where Windows is installed. Although the operating system resides on the driveC:
, this drive letter may change to something else when you start your computer in recovery mode. However, in most cases, the drive letter is.D:
We used Windows 10 for this guide, but the concept should also work on Windows 8.1 and Windows 7.
There are a few ways to back up the registry. Usually, you can use Registry Editor for selective backups or the Task Scheduler and System Restore tool to i backup completi.
There are ways to use the registry editor to back up the full registry. However, doing it and restoring from backups is somewhat complicated. You can export registry keys as REG or hive files.
Make sure you keep these things in mind before performing these methods.
You can directly export registry keys or subkeys to REG files from Registry Editor. Here’s how you can do it:
You can find the database files for your system logs within the %windir%System32config
directory. The log databases for user files are located in the %username%
school bag.
HKLMBCD00000000 as BCD-Template
HKLMDRIVERS as DRIVERS
HKLMSAM as SAM
HKLMSECURITY as SECURITY
HKLMSOFTWARE as SOFTWARE
HKLMSYSTEM as SYSTEM
HKLMCOMPONENTS as COMPONENTS
HKU.DEFAULT as DEFAULT
HKCU as NTUSER.DAT
HKCUSOFTWAREClasses as USRCLASS.DAT
The use of these names is required to overwrite the log database files when restoring these backups.
You can also use the command line interface to export registry keys and entries. You are performing the same operations as above but with the command prompt. Follow the steps below to do that:
If you want to create a backup of the entire registry, you need to use the command REG SAVE. Eg, REG SAVE HKLMDrivers D:DRIVERS /y. You can replace D: with the directory path you want. Make sure you create backups for all the keys mentioned in the previous method.
The System Restore tool allows you to create a snapshot of the system as a restore point. You can come back to this point at any time when your system has problems. This tool of course also backs up the registry. To create a restore point, follow these steps:
The Scheduler allows users to plan and execute certain tasks. With this method, you can create a backup of the log files in the% windir% System32 config folder. However, it does not create a backup for the user log files. Follow these instructions to perform the registry backup task:
There are some third party applications that you can use to backup the registry. These applications help avoid the hassle of manually selecting keys for creating backups. Make sure you read the reviews and user comments for the application before installing it.
Windows automatically backs up the registry by default in previous versions. However, this setting must be enabled manually in newer versions. You can do this using the registry editor. Follow the steps below:
