Windows 7 Home Prem x64 Will not load Explorer.exe on startup

Hi,
Ive got a laptop here that encountered the PCEU virus. I removed the HDD and placed into another machine as a slave drive to run Malwarebytes. Successfully removed 14 threats and placed back into the laptop. The PCEU virus has gone but I get a CMD box on startup trying to open a random .EXE and explorer doesnt load takes you to a c:\windows\system32 cursor. Typing explorer.exe here then loads and the OS is fully usable. How do I remove that from a startup and push explorer.exe back into a startup position??

Here is what appears in the CMD Box on start. I have obviously typed the explorer.exe to get the OS to load.

That said, wiping the drive and making a clean install of W7 is the safest thing to do:
