Corrupted registry in windows 10

Hi SanthanKarnala -

I'm Kevin B. Independent advisor and a Windows user like you. I do apologize for the inconvenience that you experiencing right now, let me help you sort things out.

How did you delete the Windows 7 on your computer? Best action to take before performing any troubleshooting is to back up your files to keep them safe. Please do backup your photos first.

Please follow the steps below and check if one of these resolves the issue that you have.

Perform SFC Scan and Repair Windows Image

-This process will perform scan for any corrupted system files or integrity violation and will attempt to repair it along with the Windows Image.

1. Open command prompt with administrator access
2. Type each command below and wait until scan is completed.

* sfc /scannow

* DISM /Online /Cleanup-Image /CheckHealth

* DISM /Online /Cleanup-Image /ScanHealth

* DISM /Online /Cleanup-Image /RestoreHealth

Quick note: While the command is running, it's expected to see the process stuck at 20 or 40 percent. After a few minutes, the process will complete successfully.

Once you complete the steps, the Deployment Image Servicing and Management tool will connect to the Windows Update servers to download and replace any damaged files in the local image for Windows 10 as necessary.

3. Close the command prompt.

Perform Clean Boot

• This process will eliminate 3rd party application running in the background of your computer along with services that are not needed to run windows. If there's any conflicting 3rd party application that causes the issue on your computer, this process will stop it.

1. Open the run box by pressing the Windows Key + R and type msconfig
2. System Configuration Utility box will open and by default you are on general tab.
3. On the General tab, click the selective startup and make sure that load system service and load startup items both have checked mark.
4. Click on services tab
5. Put a check mark on Hide All Microsoft Services > This is a very important part as if you miss to click on this, computer might not boot properly or permanently and will end up on clean installation.
6. Once Hide all Microsoft Services have checked mark on it, click on Disable All
7. Click on the Startup Tab and click open task manager. This will open another window which contains all your startup applications on the administrator account.
8. Disable all application that you're not using. You can simply just click on them and select disable.
9. Click OK , Apply and close the configuration utility

If the above method did not resolve the issue, Maybe we can perform in-place repair to repair the windows. In-place repair/upgrade or repair reinstall is a process of re-installing Windows without touching any of your applications or personal files. In this way if there's any data corruption, damaged system files or missing system files on your computer, this repair will fix or repair them.

To start we need to download an ISO file of Windows 10 and save it to your computer. Please follow the instruction on the link below to create an ISO file

After the ISO is created, follow the instructions on the link below created by PaulSey, Microsoft Agent, on how to perform repair install on your computer.

This process will take some time to complete so you need to be very patient in waiting until the process completes. Once done , restart your computer and check if the issue is resolved.

Hope this will help and have a bless day!

Thanks.

Hi SanthanKarnala -

Please do try to create an account so we can check if we can use it to repair the windows. If the new account allows exe file to run then you can use it to create the ISO file of windows and run it on your machine.

Hi kevin B, thanks for your concern, before...i created an admin account and opened pc from it, but no use and my registries are still highly corrupted in admin account also. Or, shall i create a another account and prompt from it?

Hi SanthanKarnala -

Thanks for the update. Can we try to create a new user profile and check if the same issue occurs?

Create a new user profile

• We will try to create new user profile to check if the issue happens on all windows users on your computer or just isolated on the current profile that you're using.

1. Open the command prompt with elevated access (Administrator Access)
2. Type the below command and hit enter every after command.

net user "account name" /add

(change the "account name" to any name that you preferred)

net localgroup administrators "account name" /add

(change the "account name" with the name that you put in the first command)

3. Close the command prompt and switch to the new user.

Check if the same issue occurs on the new user profile.

Feel free to reach back if you need further assistance
