Start Windows in Safe Mode to complete any of the following steps if you’re unable to access Windows normally due to the error.

1. Restore winhttp.dll from the Recycle Bin . The easiest possible cause of a “missing” winhttp.dll file is that you’ve mistakenly deleted it.

2. Run a virus/malware scan of your entire system . Some winhttp.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file. It’s even possible the error you’re seeing is related to a hostile program that’s masquerading as the file.

4. Reinstall the program that uses the winhttp.dll file . If the DLL error occurs when you use a particular program, reinstalling the program should replace the file.
   Try your best to complete this step. Reinstalling the program that provides this DLL file, if possible, is a likely solution to this error.

7. Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the winhttp.dll file. Since this DLL file is provided by Microsoft, theSystem File Checker tool should restore it.

    We rarely recommend the use of registry cleaners. We’ve included the option here as a “last resort” attempt before the destructive step coming up next.
12. Perform a clean installation of Windows . This erases everything from thehard drive and installs a fresh copy of Windows. If none of the steps above correct the error, this should be your next course of action.
