How To Fix Lagging In Windows 8.1

Reader Question:
“Hi Wally, Since I upgraded my computer from Windows 8 to Windows 8.1, I have been dealing with lagging in Windows 8.1 that wasn’t there before. The computer slowed down since the upgrade. Can you help me with that?”  - Anna P., Australia

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Windows 8.1 was released to take care of the flaws in Windows 8. Windows 8 had some software related problems as well as issues in the user interface. These issues were fixed in Windows 8.1

With the release of Windows 8.1, it seemed that most problems were solved. The upgrade fixed many problems but it also gave rise to some newer problems. Here we will see how to fix lagging in Windows 8.1 as well as how to keep your Windows 8.1 PC running smoothly.

Here are some tips to help you make Windows 8.1 run faster.

If Windows 8.1 Does Not Boot Properly

This can happen when you upgrade a Windows 7 PC to Windows 8.1. The Hybrid Boot feature makes Windows 8.1 boot up and Shut down faster but it also causes problems on some computer hardware. Turning it off will make the computer a bit slower, but it should also fix lagging in Windows 8.1 when it starts.

  1. Press Windows Key + X > click Control Panel

Making Windows 8.1 Start Faster

Many software programs try to put themselves in the list of startup programs. This launches the program in the background every time the computer starts and might cause lagging in Windows 8.1. Here is how to remove programs from startup that you don’t need.

  1. Press Windows Key + X and click Task Manager form the menu
    Lagging In Windows 8.1 -  Windows Key + X -  Task Manager -- Windows Wally
  2. Click More details if you see the compact task manager
    Lagging In Windows 8.1 -  Task Manager - Start -- Windows Wally
  3. Click the Startup tab
    Lagging In Windows 8.1 - Task Manager - Startup Tab -- Windows Wally
  4. Right-click a program > click Disable

This will stop the program from running when the computer starts.

Updating All Device Drivers In Windows 8.1

When you install or upgrade to Windows 8.1, it installs generic drivers on your computer. Hardware manufacturers release newer versions of these device drivers to fix issues and improve speed. Here is how you can install the latest version of device drivers for your computer.

  1. Press Windows Key+X > click Device Manager
    Lagging In Windows 8.1 -  Windows Key + X -  Device Manager -- Windows Wally
  2. Right-click the device > click Update Driver Software…
    Lagging In Windows 8.1 - Device Manager - Update Driver Software... -- Windows Wally
  3. Click Search automatically for updated driver software

  4. If a new driver is found, the driver will be installed for you. Do this for all devices whose drivers you want to upgrade.

This might seem a little tedious because it is tedious. But you can also use driver utilities like DriverDoc to make the job easier. This software will find and install the driver for you and it automatically detects newly available device drivers as well.

Registry Optimization In Windows 8.1

When you upgrade from Windows 8 to Windows 8.1 it’s not just a small update, it’s actually a major upgrade of your Windows operating system. Windows upgrades have a history of being a bit problematic. Usually, a clean install is the best option. You should use a trusted registry optimizer tool to take care of various PC errors and registry problems for you. It is general practice to make a system restore point when you scan your computer with a registry optimizer for the first time.
