[SOLVED] "The configuration registry database is corrupt." Windows 10 1803

[morphly]

Hi there,

I have a Laptop with a corrupt COMPONENTS registry hive. Regback folder is empty unfortunately.
SFCFix, SFC and DISM throw errors after some seconds. COMPONENTS is not totally empty so I have hope that someone can fix it.

Please find cbs.log attached. COMPONENTS.ZIP uploaded here COMPONENTS.ZIP


Regards

Managed to fix it myself.

Exported COMPONENTS hive with RegFileExport and imported it into a new clean hive.

Glad you were able to fix it on your own.

I am guessing you did something like the following?

Reg export "HKEY_LOCAL_MACHINE\COMPONENTS" "%UserProfile%\Desktop\Components.reg"
CleanComponents.bat
Reg import "%UserProfile%\Desktop\Components.reg"

But how did you make sure you imported it into "a new clean hive," e.g. CleanComponents.bat would have what in its place?


EDIT: For others who might have similar issues, I strongly advise reading the following before attempting repairs to the COMPONENTS hive: Restoring a Backup of the COMPONENTS Hive - What are the issues?

Basically what I did was the following:

Using RegFileExport from NirSoft (as normal windows tools would refuse to load the registry hive)
RegFileExport.exe [Path to broken COMPONENTS hive file] COMPONENTS.reg
Luckily this did not produce any errors and I did a quick check with notepad if the contents looks like a regular reg-file.
Then I created an empty reg hive to import to using this Powershell code Peter Hinchley : Create a New Registry Hive using PowerShell (comment out line 123)
reg load HKLM\TEMPHIVE [Path to empty hive file]
Open COMPONENTS.reg with an editor and search&replace all occurrences of "[HKEY_LOCAL_MACHINE\COMPONENTS" with "[HKEY_LOCAL_MACHINE\TEMPHIVE" - save the file
reg import COMPONENTS.reg
reg unload HKLM\TEMPHIVE

Then I copied/renamed the hive file to it's original destination and ran "sfc /scannow" successful. Also patches did instantly install properly afterwards
