I just install Windows 8.1 on my home PC, installing SQL Server on it and found that activeds.dll file was missing. I haven’t install anything, just regular MS products and updates. So, how can a file is missing. On searching I found that DLL was present, but seems corrupted, maybe some disk writing fails or something. I start thinking to reinstall machine, as it is just been installed and got corrupted. But at last minute I found a command that not only detect all corrupted files in windows system but repair them as well. Here is steps
- Open CMD with Admin rights
- run sfc /scannow
It repairs few basic windows DLL that got corrupted maybe for any reason, disk fail, some program change them or whatever. It save me few hours to re-install and then update 4GB on internet again.
