If suddenly your root folder refuses to open, defaulting to some other action
If you are trying to open your drive and browse its contents (normally by clicking on its icon), but instead of showing the contents Windows tries to perform some other action, such us turning on BitLocker, or anything, then, most probably, some program you used recently to customize the context menus changed the registry.
You can revert the default action of a folder to “Open”, by opening the Registry Editor (press Win+R and write “regedit” without the quotes), and then going to HKEY_CLASSES_ROOT – Drive – Shell.
At the right pane of the Editor, you will see the “Default” property of the Shell. Right click on it and select “Modify”.
Normally the box that appears there is empty, which causes the problem. Write in the Value box the word “none” (without the quotes), and close the editor. Now opening “My Computer” and browsing your drives should work. Enjoy!
