Recently a rootkit was revealed which silently enables test mode in order to install unsigned drivers into the Windows 圆4 system (32-bit versions of Windows are not that strict and allow drivers with invalid signature to be loaded in kernel-mode). If you do not have any clue what could have enabled testmode you're strongly advised to run antivirus and anti-rootkit tools like GMER. Recoverysequence Ĭaution: If you have recently installed an unsigned driver or connected a device which comes only with unsigned drivers then disabling testmode might break the device or render it useless as the driver will not be loaded any more. It might look as follows: Windows Boot Loader You can leave this step and proceed to the second step. If you don’t see the mentioned update, you need not uninstall any update. Then look at the Windows Boot Loader section and check for testsigning parameter. After loading all installed updates, check for update KB971033 and uninstall.
To verify whether you're running in testsigning mode open up an elevated command prompt and type: As Windows 7 does not allow to install unsigned kernel-mode drives (unsigned/untrusted user-mode drivers are allowed) you need to enable "testsigning" mode in order to install it. This is typically done if you need to install an unsigned driver. It looks like either you or any program has set your Windows 7 into test signing mode.
