IS YOUR COMPUTER SLOW? RUN LIKE NEW
If they are not maintained, computers lose performance over time. Norton Utilities Ultimate can help significantly improve the performance of your Windows computers.
Applicable for: Windows
Computer takes a long time to start
From virus infection to conflicting startup items to multiple third-party security products, there are several reasons that can cause your computer to start slowly. Your Norton product can help you with some of the causes and reduce your computer startup time.
Before you follow the steps, make sure that you get your PC tuned up using your Norton product's performance features. For more information, read Fix slow computer problems.
STEP 1: Manage startup items
You may have many programs loading at startup that can slow down the startup process. With Norton's Startup Manager feature, we can help you manage your startup programs and reduce the startup time.
-
-
Open your Norton device security application.
-
On the left panel, click Performance.
-
On the Performance dashboard, in the Startup Manager tile, click Open.
-
In the When to launch column, select one of the following for each listed program:
Your options are:
-
Startup: Launches the program during device startup.
-
Disabled: This option prevents the program from launching when your device starts. Select this option for programs that you do not use.
-
Delay: This option allows the program to load only after the device startup completes. You can use this option to delay the start of a program when you turn on your computer. The program will run at a later time.
You can use the Launch Delayed Apps option to run all the startup programs you chose to delay manually.
-
-
STEP 2: Uninstall any non-Norton security product
Each security software is designed to work independently on a computer. Multiple security solutions on a computer are generally not optimized to work together, resulting in performance degradation.
-
Press the Windows + R keys to open the Run dialog box.
-
Type in the following text, and then press Enter.
appwiz.cpl
-
In the list of currently installed programs, select the non-Norton security product, and then click Uninstall or Remove.
-
Follow the on-screen instructions.
-
When the uninstall completes, restart the computer.
You can also read the program documentation or contact the program manufacturer for instructions to remove a non-Norton security product from your computer.
