If you notice slow Windows startup after installing Bitdefender App, especially immediately after installation, this does not necessarily indicate an issue with your PC. After installation, Bitdefender performs several initialization and security-related tasks in the background. These processes can temporarily affect startup time.
Restart Windows a couple of times
Before changing any Bitdefender settings, restart your computer once or twice.
This gives Bitdefender time to complete its initial setup. In many cases, Windows startup time will return to normal after these first few restarts, and no further action is needed.
If your computer still takes a long time to boot up, check the Early boot scan option in Bitdefender. When enabled, this feature performs a security check early in the boot process and can increase the increase startup time.
Follow the steps below to disable Early boot scan and see if Windows starts faster.
Step 1. Open Bitdefender App
Open Bitdefender App using one of these methods:
- Double-click the Bitdefender shortcut
on your desktop. - Search for Bitdefender in the Windows Start menu.
- Click the Bitdefender icon in the Windows notification area.
Step 2. Open Antivirus settings
- In Bitdefender App, click Services from the menu on the left.
- Go to Protection.
- Locate the Antivirus panel and click Open.
Step 3. Turn off Early boot scan
- At the top of the Antivirus window, access the Advanced tab.
- Scroll down until you find Early boot scan.
- Turn off the Early boot scan switch. The switch becomes gray when the feature is disabled.
Step 4. Restart your computer
Restart Windows once or twice, then check whether startup time has improved.
If Early boot scan was contributing to the slow Windows startup, the computer should start faster after you disable the feature.
