Windows 10: Registry Backups

Based on a lot of Googling and information from this forum I created the below batch file to backup my Windows 10 registry from an elevated cmd prompt. Everything is working perfectly but I have a question on what I'm backing up. Are there other registry hives/locations that I should include?

set curr_date=%DATE:~10,4%-%DATE:~4,2%-%DATE:~7,2%
echo %curr_date%"

mkdir "D:\Registry Backups\Backup %curr_date%"

REG SAVE HKLM\Software "D:\Registry Backups\Backup %curr_date%\SOFTWARE"
REG SAVE HKLM\Security "D:\Registry Backups\Backup %curr_date%\SECURITY"
REG SAVE HKLM\System "D:\Registry Backups\Backup %curr_date%\SYSTEM"
REG SAVE HKU\.Default "D:\Registry Backups\Backup %curr_date%\DEFAULT"
REG SAVE HKLM\SAM "D:\Registry Backups\Backup %curr_date%\SAM"
REG SAVE HKCU "D:\Registry Backups\Backup %curr_date%\NTUSER.DAT"
REG SAVE HKCU\Software\Classes "D:\Registry Backups\Backup %curr_date%\USRCLASS.DAT"
REG SAVE HKLM\BCD00000000 "D:\Registry Backups\Backup %curr_date%\BCD"

Registry Backup - Question

Registry Backup

I am reading a book, Windows 10 Anniversary Update. It makes these two statements.

• File History also keeps a copy of your Registry.
• Every time you start your computer, it makes a backup copy of that Registry.

Where and how do I find these copies?

Thanks,

Jerry

How to backup and restore registry using only win10 iso command prompt

In a link it suggested several registry troubleshooting steps for a Windows with black screen.

For Windows 10 1909 how do you backup and restore one registry change using a windows 10 iso command prompt?

If more than one registry entry is modified how do you backup and restore a second change?

In addition to modifying one or two commands how do you backup and restore the whole registry when the only access is via a windows 10 iso command prompt?

 

registry fix

Hi,

Thank you for posting your query on Microsoft Community.

As per the description, I understand that you are facing some issues using Windows 10.

I would like to know some information.

• 
  What registry fix are you trying to run?
  
• 
  What is the exact issue that you are facing?
  
• 
  Have you taken a backup of all your data?
  

I would suggest you to take a backup of all your data before doing any changes in the registry keys. If you do any incorrect changes to the registry you won’t be able to boot the computer.

Disclaimer: This section, method, or task contains steps that tells you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps
