Windows Wireless LAN 802.11 Extensibility Framework using too much CPU power

Anonymous

Recently, my computer's been running significantly slower. A quick look at my task manager showed me that the "Windows Wireless LAN 802.11 Extensibility Framework" was using up 40+% of my processing power, and I have no idea why or how to reduce it. I'm fairly certain it's doing things it shouldn't be doing, but again, I have no idea what to do. Any help would be greatly appreciated!

Hi,

The Windows Wireless LAN 802.11 Extensibility Framework provides an interface to Windows wireless security and connectivity features for the drivers of wireless network adapters.

Let’s try these methods and check if it fixes the issue.

Method 1: Run System Maintenance troubleshooter and check.

a) Press Windows and X key together and select Control Panel.

b) Click on Troubleshooting.

c) Click on View all option on the left side of the Windows.

d) Click on System Maintenance option.

e) Click on Next and follow the onscreen instructions to troubleshoot the issue.

Method 2: C heck the functionality in safe mode with networking.

Step 1: Start your computer in safe mode with networking and check the CPU usage.

Refer this link to start the computer in safe mode.

http://windows.microsoft.com/en-IN/windows-8/windows-startup-settings-including-safe-mode

If it works fine in safe mode with networking, let’s place the computer in a clean boot state.

Step 2: Perform clean boot.

Clean boot will help us identify if any third party applications or startup items are causing the issue.

To do this, follow steps from this link:

**Note:**After checking the functionality in clean boot, follow the suggestions under “How to reset the computer to start as usual after troubleshooting with clean boot”.

Keep us updated with the status of the issue to assist you further.

    I had the same issue, one of my CPU cores was entirely taken up by the Extensibility Framework.

    Disabling Wi-Fi, killing the task and re-enabling Wi-Fi did it for me, so thanks Pedro and the other users for this tip.

    However I find it very alarming that such a severe issue hasn't been addressed by Microsoft for almost two years now. Also, official Microsoft forum experts who repeat the same non-working advice over and over do not seem too trustworthy to me...

    I made a reply to thank you! The **** that the forum mod spouted didn't work, yours did instantly. Weird as **** though.

    Same problem ThinkPad Yoga S1, Intel Wireless AC-7260, Windows 8.1

    Didn't notice any problem for weeks but all of a sudden every 3 days or so machine goes flat in a few hours instead of lasting all day...

    Reluctant to remove VC++ I have to say....
