To delete unwanted or corrupt .dll files, you will need to find them by making hidden files visible, unregister them through the command prompt, and then delete them manually from their source folder. It is very important that you know that the file is not a required Windows system file. Removing DLLs that your computer relies on can render your PC unbootable, so don't delete a file unless you know exactly what it is and why you don't want it on your PC. Steps-
1 Boot your Windows PC into Safe Mode. This ensures that if you have an unwanted app, such as spyware, that relies on the DLL to work, it won't prevent you
from deleting the file. To boot your computer up into Safe Mode: - Click the Windows menu and select Settings.
- Click Update & Security.
- Click Recovery.
- Click Restart now' under "Advanced startup."
- When your PC reboots, click Troubleshoot.
- Click Advanced options.
- Click Startup Settings and select Restart.
- When you see the list of startup options, press 4 or
F4 as indicated to boot into Safe Mode.[1]

file name (or part of the file name) into the "Search This PC" field at the top-right corner of the window. Click the purple arrow to display the search results—when you find the file, right-click its name, and then select Open file location from the menu.

how: - Type cmd into the search bar next to the Windows start button (you may have to click a magnifying glass first to see it).

- Press Enter to run the command.
- You can use the dir command at the prompt to view a list of all files in the folder. To see just
the DLL files, use dir *.dll instead.
-
13 Unregister the DLL file. At the prompt, type regsvr32 /u filename.dll.[2] Replace filename.dll with
the name of the file you want to delete, and then press the Enter key to run the command. This makes it possible to delete the DLL. -
14 Delete the file. You'll use the Command Prompt to do so: - Type del /f
filename.dll, replacing "filename.dll" with the name of the file. The /f flag tells Windows to delete the file even if it's read-only.[3]
- Press Y to confirm if prompted.
- Once the file is removed, undo the changes you made in the File Explorer options and reboot your computer as normal.
