How to remove startups from registry

You know that it's not sufficient to avoid starting programs on startup by disabling the programs in startup option. They live in the registry. Some times those registries also should removed in-order to avoid them starting on the startup.

Get RUN and type regedit.

Now registry will open.You should go through two things. When we installing app it could be a 32 bit one or 64 bit one. The startup registry files of 32 bits apps will build in HKLM or HKCU (HKLM-HKEY_LOCAL_MACHINE , HKCU-HKEY_CURRENT_USER) , HKLM/Software/Wow6432node/Microsoft/Windows/Current Version/Run
or
HKCU/Software/Wow6432node/Microsoft/Windows/Current Version/Run

Startup registry files of 64 bit apps will build in

HKLM/Software/Microsoft/Windows/Current Version/Run
or
HKCU/Software/Microsoft/Windows/Current Version/Run

Deleting the remaining registry files of a app that you dont want to run on startup will work well. Specially with the malwares. Most malwares created to execute at the startup. Deleting registry files of that malware like this would end up the malware activities on your computer toatally.
