Safe Mode starts Windows in a basic state, using a limited set of files and drivers, which is used to narrow down the cause of issues on the computer. If the issue is not observed in Windows Safe Mode, then it is highly likely that the cause is third-party software.
Three versions of Safe Mode:
- Safe Mode
- Safe Mode with Networking - used when internet access and network access are needed.
- Safe Mode with Command Prompt - used when Command Prompt is needed.
