In fact, there are many ways to use unsigned drivers in 64-bit win7. As shown in the above figure, after booting, press F8 key in the login waiting interface and enter the advanced startup item of Windows system. We will find that there are some differences with the original XP system. In the last item, driver signature enforcement is disabled, and drivers without digital signatures can be used after entering the system.
This solution is very simple, but it can only be set when the computer is turned on, and it returns to the original state after the computer is restarted. Is there any way to solve it once and for all? There is still a way to turn off the mandatory driver signature requirement in Windows 7 system. The command to turn off the mandatory driver signature is:
bcdedit.exe-set load options trivial _ integrity _ checks
Open the CMD command line as an administrator, then enter the above command, and restart the computer after completion, so that drivers without digital signatures can be used on 64-bit win7 system at any time. Of course, this operation also reduces the safety factor of the system, so it is not recommended to shut it down all the time, and it is not recommended for inexperienced users to use it. Developing good safety awareness is the first step of safety.
bcdedit {bootmgr}/set nointegritychecks yes
The wireless network card cannot be started under the Windows Server 23 operating system. The yellow exclamation mark is always displayed in the device manager.
The reason for this problem is that Windows 23 Server has a problem in allocating pci resources for wireless network cards, and the pci configuration items are blocked in the notebook bios and cannot be modified.
To solve this problem, some people choose to replace the supported wireless network card, but they don't need to replace the wireless network card. The solution is as follows:
Open the Explorer menu, Tools-Folder Options-Display, remove the checkmark before the option of "Hide Protected Operating System Files", open the root directory of drive C, right-click the file property of boot.ini, and remove the read-only property. Open the boot.ini file, change the noexecute=optout item to execute=optin, save the changes, restore the read-only property of boot.ini, and restore the hidden protected operating system file. Restart the computer and enter the device manager to see that the wireless network card has been enabled!
the driver in win7x64 system requires a digital signature, otherwise it can't be used normally. But sometimes it is necessary to use drivers without digital signatures, but the drivers can't be used after normal installation. At this time, we can only use the drivers after pressing F8 to enter the system in the mode of "disabling driver signature enforcement" when booting.
At present, there is no perfect solution to this problem, only a temporary solution:
Temporary solution: Run, input: bcdedit/set testsigning on Enter
and then restart
to turn off the forced digital signature
But there will be a prompt watermark after booting to the desktop, but there is no substantial inconvenience in use.
