How to Start Microsoft Windows in Safe Mode
To find out if the problem lies with any of the aforementioned components, follow these steps to start Word in safe mode:
Go to the Windows Start menu and select Run. Or, press the keyboard shortcut Windows key+R. Type winword /safe, then select OK. Or, press and hold the Ctrl key and double-click the Word shortcut. When Word opens, Safe Mode appears at the top of the window.
Find the Problem
If Word starts properly, then the problem lies in the registry data key or something in the Office startup folder. To troubleshoot Word, disable add-ins, use the Office Repair Utility, or delete the data registry subkey, as well, as this might be the cause of startup problems in Word.
If Word doesn’t start correctly in safe mode, or if you don’t want to edit the registry, reinstall Word. Back up your settings first before making any changes to the registry.
