How to remove StartIsBack without access to system?

Question

StartIsBack made my system unusable (start menu is constantly flashing, can't access anything). Therefore, I can't remove this program via uninstall. How can I remove it from system files via other system?

Solution

Option 1: You can disable the auto-startup of StartIsBack program from msconfig.exe(C:\Windows\System32\msconfig.exe) or disable it using Microsoft's Autoruns and reboot, so StartIsBack won't be loaded, and you can uninstall it easily.
(or)
Option 2: You can uninstall that program in safe mode:

Note: These are the steps to boot into safe mode in Windows 8 and Windows 8.1

1.press the Power button at the Windows login screen or in the Settings charm. Then, press and hold the SHIFT key on your keyboard and click Restart.

2.Windows asks you to choose an option. Press Troubleshoot.

3.In the Troubleshoot screen, press Advanced options.

4.In the Advanced options screen, press Startup Settings.

5.You are informed that you are about to restart in order to change several Windows options, including enabling Safe Mode. Press Restart.

6.Your computer restarts again and displays nine startup settings, including Safe Mode, Safe Mode with Networking and Safe Mode with Command Prompt

7.Press the F4 key on your keyboard to enable Safe Mode, Windows 8 and Windows 8.1 now boot to safe mode. Now you can uninstall the "StartIsBack" program and restart the pc normally.

Can you get to run? Try running ‘StartIsBackCfg /uninstall’ from Run dialog

You can also run the installer again. If its already installed you should be given an option to repair or uninstall the application.

@Psycogeek: Post that as an answer and get my upvotes. Tip for those searching for it: It's under %LOCALAPPDATA%\StartIsBack (enter that in the address bar anywhere)

StartIsBack registers a DLL which can't be disabled with msconfig or autoruns
