Just make sure it was working properly before you deleted it, else you might undelete a corrupted or malicious file. The same DirectX installation program works with all versions of Windows and will replace any missing DirectX file. Sometimes, though not often, the version included on the disc is a better fit for the program than the latest version available online. It’s even possible that the d3d11.dll error you’re seeing is related to a hostile program that’s masquerading as the file. Fortunately, the file is provided by Microsoft in at least some versions of Windows, so the System File Checker tool (the sfc command) should restore it. This step is most useful for replacing DLL files that are not supplied by Microsoft, but it could help with your d3d11.dll problem if this program also provides a copy of the file and the previous troubleshooting ideas weren’t successful. If the hardware fails any of your tests, replace the memory or replace the hard drive as soon as possible.
