To disable safe mode on a computer that’s running on Windows 7, access the System Configuration utility via the Run window and turn off the Safe Boot option. To do the same on a mobile device, reset the device after removing and reinserting the battery.
To access the System Configuration utility, press R while holding down the Windows key, type “msconfig” in the Open field and click OK. Click Yes if the User Access Control prompt appears on the screen. Open the Boot tab, uncheck the box next to the Safe Boot option and click OK. Once you restart the computer, Windows 7 should boot into normal mode. If that fails, tap F8 while Windows 7 is booting up to access the Advanced Startup Options screen and then select the Start Windows Normally option.
To disable safe mode on a mobile device, first make sure that the Menu key is not stuck; that can make the device boot into safe mode automatically. Turn off the device and remove the battery. If you're dealing with a phone, remove the SIM card as well. After waiting for at least 30 seconds, connect the device to a power source via the charger, reinsert the battery and the SIM card, and turn on the device without pressing any keys. If that fails, remove any recently installed applications that might prevent the device from booting normally and then reset the device.
