OpenVPN & Windows 7

There’s a great GUI out for OpenVPN & Windows, located here.

However, this GUI includes an old OpenVPN, that is no longer compatible with Windows 7 and Windows Vista.

The TUN/TAP driver will be blocked due to compatibility issues, and when trying to connect to a VPN, you’ll get an error along the lines of:

All TAP-Win32 adapters on this system are currently in use

The simplest fix, is to install the GUI package (including the old OpenVPN binaries), and reinstall OpenVPN afterwards.

You can find the latest OpenVPN binaries here and the latest version, when writing this post here.

This will overwrite the old files and update the driver with a Windows 7 compatible driver.

Try to connect now, everything should work like a charm. 🙂

Turning off Driver Signing in Windows 7

To disable it, as administrator, open cmd.exe (win button + R -> cmd -> [enter]), and copy paste the following 2 lines:

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON

Reboot, enjoy. No more annoying messages. 🙂

Windows 7 + iPhone tethering

If Apple was so kind to give you tethering (and didn’t silently remove it after an update), or if you just happen to have enabled it using, let’s say, the alternative method. And you happen to be forced to use Windows, and you really are tired of XP, and Vista surely isn’t an option; you’re probably running Windows 7.

To enable tethering on the iPhone + Windows; just pair the bluetooth devices (I actually haven’t tried with USB yet, and don’t really plan on doing that), Windows will start to QQ about it being unable to find a suitable driver for the iPhone… I even installed iTunes to see if the message would go away, but apparently it won’t. I’ll have to do some more Googling later on.

Anyway, to tether, just go to “Control Panel” > “View devices and printers” (under “Hardware and Sound”) > Devices > $iPhone_Name (it has a fancy yellow warning sign next to it…).

Right click, “Connect using” > “Access point”.

Simple enough. Pick “Public network”, just to be sure (though, your ISP should already block most direct connections between devices, and your iPhone won’t forward any ports I guess/hope).

And don’t forget to disable WiFi or unplug your network cable if you want to test it at home.

Oh, right, and I probably should give you a bunch of warnings about data consumption and that AT&T might brutally murder you and your family if you dare using tethering (as far as they can actually check you’re tethering, and if they can, I’m pretty sure they’ll be violating a couple of privacy laws). As for the customers of the 95% other decent providers who allow tethering and aren’t living in the middle ages, have fun using it. Finally work can be done on the train/while waiting/… 😉

HP ProtectTools and Windows 7

If you’re having troubles using HP ProtectTools and Windows 7, you’ll probably using an outdated version of ProtectTools. Eventhough HP tells you this is the latest version for your notebook.

A simple fix, is to download the latest version, which is model independent.

Be sure to completely uninstall the previous version, reboot, and reinstall the latest version. I can now successfully login using the biometric fingerprint device.
