Can someone direct me where to find the solution?
You need a client to open those wallet file/s. Did you use a standalone executable? Because this one doesn't go through any installation process so no shortcuts can't be found. You only need the .exe file to open it. Meanwhile the Windows Installer as exactly as it says it installs and creates shortcuts and registry entries for you.
Since the wallet files is still on your laptop, Just download standalone executable or windows installer [Pick which one suits you] and you can access your wallet/s again since both of them opens the wallet on %appdata%/Electrum by default
