- Windows Repair (WR) uses - for A LOT OF repairs - a batch file (*.bat) to run a number of MSDOS commands. If you somehow interrupt the execution of that batch file (e.g. by pressing Ctlr-C) then the batchfile will respond this way. So, the next time you run WR avoid touching your keyboard.
- Recommendation: To avoid nasty consequences, rerun the repair(s).
