Newly installed Windows 10 system, how to use it? Is there an application that will start soon? If not, then take a look at the setup method for Win Quick Launch.
The first step is to open the registry editor first. You can open the running window with the Windows logo key +R, type “regedit” and press Enter to start.

The second step, in the left side of the registry, expand the following path: HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Serialize, you may not find the last Serialize item, it does not matter, we You can create a new item under Explorer. Right-click on the Explorer item and select “New”——“Item” and name it "Serialize".

The third step, in the right side of the Serialize item, by clicking the right mouse button, create a new DWORD value, the name is "StartupDelayInMSec" (without quotes), and then double-click the key to change it to ”0“ (without quotes), you can be sure.

Restart the computer, the settings will be effective. Of course, in the Windows 10 system, if there is a startup item in the folder, it will start quickly. If there is no startup item in the folder, then I am sorry, no rice, you can't see any changes.
