How To Fix Windows 8.1 Speed issues after upgrading from Windows 8

Reader Question:
“Hi Wally, After upgrading my laptop from Windows 8 to Windows 8.1, I noticed that the speed went down a lot. What should I do to increase Windows 8.1 speed right now?”  - Mary P., USA

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 was in serious hot water when it was released due to some controversial changes to the Windows user interface. However, after receiving the feedback and making the necessary changes, Windows 8.1 has regained the trust and support of Windows 8 once again.

Windows 8.1 Speed - Cover -- Windows Wally

Speed has been Windows 8′s strong feature from day one but upgrading from Windows 8 to Windows 8.1 has been seen to have decreased its speed for many users.

For most users, it’s due to problems caused by upgrading Windows on an existing installation (rather than a clean install). In this case, upgrading Windows 8 to Windows 8.1 causes Windows 8.1 speed problems.

Troubleshooting Windows 8.1 Speed Issues

You can use troubleshooting tools built-into Windows 8.1 to scan for and fix Windows 8.1 speed issues. Follow these steps:

  2. Click Troubleshooting to open it, it may take a few seconds for it to show up.

  7. Click Next to continue, and wait for the scan to complete.

User Profile Issues

Believe it or not but corrupt user profile issues are a valid cause of Windows 8.1 speed issues. If you have more than one user accounts set up on Windows then try logging-in from that user account and see if the speed problem goes away. If the speed is normal when you’re using the other user profile then you need to delete the slow user profile and make a new one.

  1. Use Windows Key + I to go to settings on the Charms Bar.
  2. Click Change PC settings on the bottom.

Fix the Windows 8.1 Registry

Windows 8.1 speed issues can very well arise from registry problems caused by the update. The Windows registry is a complex component and upgrading Windows always has a high risk of causing such problems which can only be fixed by scanning and optimizing the Windows registry.

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.
