1] Using System File Checker
This will repair potentially corrupted or damaged Windows system files. You will need to run this command from an elevated command prompt.
You can also use our freeware FixWin to Run the System File Checker utility with a click.
2] Disable problematic add-ons of Explorer
Check if Windows Explorer has addons installed. Installed Add-ons are usually the culprit! Check if you have installed any helpers or add-ons to your explorer.exe. Uninstall or disable them. Often, even 3rd-party shell extensions can cause Explorer to crash on particular actions. Several programs add items to the right-click context menu. To see them in detail, you may download the freeware utility Nirsoft ShellExView. It will let you view & disable suspect 3rd party shell extensions. Using the trial & error method, you may disable/enable the extensions to try and identify if any of them are causing a problem. ShellExView can also be used for solving context-menu problems in Explorer, like, say, if the right-click is slow.
3] Use the Program Compatibility Troubleshooter
There might be cases where the program that you are trying to run was not able to run on your newer operating system. So, you can now use the Program Compatibility Troubleshooter to run it with compatibility settings for an older version of Windows.
4] Run DISM
To do so, hit the WINKEY + X combination and click on Command Prompt (Admin). Now enter the following three commands sequentially and one by one and hit Enter:
Dism /Online /Cleanup-Image /CheckHealth Dism /Online /Cleanup-Image /ScanHealth Dism /Online /Cleanup-Image /RestoreHealth
Let these DISM commands run and wait until they execute.
5] Scan the file for exploits
You can also try to run a malware scan using Windows Defender or a free second-opinion, standalone, on-demand antivirus tool like Kaspersky or Dr. Web Cureit.
6] Replace the file from a trusted source
The files mentioned above are located on this path-
This PC > C:\Windows\System32.
This PC > C:\Windows\SysWOW64.
So, get the new file from another computer with the same file version number preferably.
Then, you need to boot into Safe Mode. After that, navigate to the path mentioned above. And replace the file using a USB Drive or other external storage devices.
Next, you need to re-register this dll file.
Open Command Prompt by searching for cmd in the Cortana search box and run it with Administrator level privileges.
