Windows 10 TrendNet TEW-726EC Wireless Adapter Driver Problem

I just installed windows 10 and I can only connect to the internet using an Ethernet cable bridged off of my laptop running windows 8.1. When I install the drivers from my usb containing the drivers found on the TrendNet website, it says it installs, but the trendnet application doesn't open and the wireless adapter still doesn't work. I try to troubleshoot but windows gives me an error stating an error is preventing the troubleshooter from starting. Any ideas to what a solution may be? because I really don't want to run my laptop at the same time as my PC just so I can connect to the internet.

My first suggestion would be to
Re-download the driver package from here
Use 7zip to extract the contents of the zip file and then copy
\Drivers\Win81x64 or \Drivers\Win8x86 to external media (CD, DVD, USB, whatever) depending on your system architecture 32 or 64 bit.
Then uninstall anything you've installed up to this point regarding software or drivers relating to the problem device especially any programs that came as part of the package.

Go to device manager, find the problem device, right click it and choose uninstall, if prompted, also select remove drivers.
Now use device manager to install the drivers from the media you created above, manually.
  1. Open the Device Manager.
  2. Right click the device you wish to change the drivers for. You can select Properties > Driver > Driver Details to check you have the right device.
  3. Choose Update Driver Software.
  4. Select Browse My Computer For Driver Software.
  5. Select Let me pick from a list of device drivers on my computer.
  6. Select Have disk...
  7. Select Browse..
  8. Navigate to the extracted folder and double click on the .inf file
  9. Hit OK, then Next and the driver(s) will then begin to install.
