How do I scan win10 registry for corrupt item?

Anonymous

My windows 10 pro have a black screen of the death issue.

When I boot up the system , the screen will goes black without cursor occasionally, but the system is running and not freeze, when I press the shift button 5 times, it will have a sound to prompt.

So I had try all possible solution from google, reinstall windows, update driver ,disable fast boot etc but no luck. I have call the main board manufacturer and said this is known issue and wont be fix because my mb model is 5 years old.

End up when occur the black screen on logon screen, I have to wait few minutes ensure the hdd led on case is not lighting and press the power button 5s to hard power off.

my first question is windows 10 builtin sfc.exe to check the system file and chkdsk to check hdd sector. But how about registry? I search in google , the scanreg.exe is gone, so what should I use to ensure registry is fine.

my second question is , do I really need

to run chkdsk and sfc once after hard power off even I ensure the hdd is not reading and writing?

sorry to my English which is not my primary language.

thank you very much.

You should run SFC (and possibly DISM)

System file check (SFC) is a utility built into the Operating System that will check for system file corruption. The sfc /scannow command (System File Check) scans the integrity of all protected operating system files and replaces incorrect, corrupted, changed, or damaged versions with the correct versions where possible. When it cannot repair the damage, DISM should be run to fix as many errors as possible.

To Run SFC (Time required - 5 to 15 minutes) -

Type cmd in Windows Start Search box

Right click on cmd

Run As Administrator

Type or copy / paste sfc /scannow and hit Enter

When you have finished it will say one of three things

a. Windows did not find any integrity violations (a good thing)

b. Windows Resource Protection found corrupt files and repaired them (a good thing)

c. Windows Resource Protection found corrupt files but was unable to fix some (or all) of them (not a good thing - DISM needs to be run)

(It may also give the message - Windows Resource Protection could not perform the requested operation. Then you need to run SFC in Safe Mode. Safe Mode - https://support.microsoft.com/en-us/help/17419/...)

Reboot your computer after SFC finishes

Note - You may have to run SFC up to 2 to 3 times to fix all problems

Run DISM (Time required - 15 to 30 minutes) - If you get message - Windows Resource Protection found corrupt files but was unable to fix some (or all) of them, then you need to run DISM

Type cmd in Windows Start Search box

Right click on cmd

Run As Administrator

Type or copy / paste following and press Enter

DISM.exe /Online /Cleanup-image /Restorehealth

Reboot your computer after DISM finishes

Note - After running DISM, it is a good idea to re-run SFC /scannow to make sure all the issues were fixed.

If you get the error message cannot find source files you need to have an ISO file mounted and need to specify where it is located with the below command

(The ISO must be exactly the same version as the running OS. An ISO of 10586.0 will not repair a running system of 10586.35 because it has additional updates and files)

DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\Sources\Install.wim:1 /LimitAccess Where X is the drive letter where the ISO is located. Simply change the X to the correct drive letter

If you do not have an ISO you can make one. The instructions are @ https://www.microsoft.com/en-us/software-downlo...

(Optional, recommended for techies - Analyzing Log file - Assuming Windows is installed on the C: drive (it usually is) then the log file can be found at C:\Windows\Logs\CBS\CBS.log - https://support.microsoft.com/en-us/help/928228...)

Answer 2

I thought you doesn't really look my question, and just copy and paste the answer from other thread that I saw.

I sure to know how to run the sfc.exe, that why I rise out sfc.exe is not equal to regscan.exe

my question is - (windows 10 builtin sfc.exe to check the system file and chkdsk to check hdd sector. But how about registry? )

There is no built-in tool now as scanreg.exe has been discontinued. No replacement either.

This is only possible through third party tools. (I don't have recommendations for third party tools as a third party tool is a potential risk to the computer)

Hello, Many users are having the same/similar problems & if you can log in via safe mode the solution is to turn off use sign-in info to auto finish setting up device after update or restart in Windows 10.

For Windows 10 (Version 1709), select the Start button, select Settings > Accounts > Sign-in options, then make sure Use my sign in info to automatically finish setting up my device after an update or restart is turned off.

For previous versions of Windows 10, select the Start button, select Settings > Update & security > Window Update > Advanced options, then select the check box next to Use my sign in info to automatically finish setting up my device after an update.

Another potential solution is to remove any USB devices (wireless mouse, keyboard, external hard drive/s) & wait to see if boot continues, if not then to restart with devices still disconnected (if possible).
