Locked out from regedit

I unwittingly locked myself out from windows by process the below instruction with a mistake. Instead of creating a string value, I used a DWORD. Currently, I'm locked from making any changes or starting of any application.

Could anyone help me out please?

Reference:

Applications - Restrict Applications Users Can Run

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer. Value Name: RestrictRun

Open your registry and find the key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer]

Create a new DWORD value and name it "RestrictRun" set the value to "1" to enable application restrictions or "0" to allow all applications to run.

Then create a new sub-key called [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer\RestrictRun] and define the applications that are allowed. Creating a new string value for each application, named as consecutive numbers, and setting the value to the filename to be allowed (e.g. "regedit.exe" and "calc.exe").
