wat does regedit means


regedit is an an inbuilt Microsoft Registry Editor. To start the regedit.exe go to Start>>>Run>>> type regedit and click OK. The Microsoft Registry Editor (regedit.exe) enables you to view, search for, and change settings in your system registry, which contains information about how your computer runs. Although you can use Registry Editor to inspect and modify the registry, doing so is not recommended, because making any incorrect changes can damage your operating system. Please go to http://en.wikipedia.org/wiki/Windows_Registry for more details.

how i can reuse the norton 360 v 4.3.0.5 Its trial period is expired. Plz send me product key or trial reseter. special thanks


Please remove the existing version of Norton program from the control panel, then go ahead and delete all Symantec and Norton files from the computer's C or D drive.

After that, open your registry and first take a back up just in case anything get deleted by mistake.
Then delete all Norton and Symantec files from HK CURRENT USER, HKEY LOCAL MACHINE, HKEY USERS, HKEY CURRENT CONFIG.

You can click on the SOFTWARE folder in each class to find the Norton files if any.
To open your registry editor, type regedit in RUN command (windows key+R)

After that you can again install a trial version of Norton for 30 days.
