How to Clear Out Old Windows Version From Registry
- 1). Download and then install a free registry cleaner. These programs scan your Windows registry and examine every entry. If any erroneous or inactive entries are found, they are then either fixed (in the case of entries that have errors) or deleted (in the case of entries that are inactive).
- 2). Open the registry cleaner.
- 3). Click "Registry."
- 4). Click "Scan." A typically registry scan only takes 30 seconds to one minute to complete.
- 5). Click "Fix All." This will automatically clear out any entries that are left over in your computer's registry from an old version of Windows.
