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 to enter the advanced startup item of Windows system, and we will find that it is somewhat different from the original XP system. The last item is to disable driver signature enforcement. According to this item, unsigned drivers can be used when entering the system. Of course, you can also load unsigned drivers in debugging mode, which is not recommended here.

This solution is simple, but it can only be set when the computer is turned on, and it will be restored to its original state after the computer is restarted. What can be done 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 forced driver signing is:

Bcdedit.exe- Set the load option to disable _ integrity _ checking.

Open the CMD command line as an administrator, then enter the above command, and restart the computer after completion, so that you can use the driver without digital signature on the 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 down all the time, nor is it recommended for inexperienced users to use it. Cultivating good safety awareness is the first step of safety.

The wireless network card cannot be started under the Windows Server 2003 operating system. The yellow exclamation point is always displayed in the Device Manager.

The reason for this problem is that Windows 2003 Server has a problem in allocating pci resources for wireless network cards, and pci configuration items are blocked in the notebook bios and cannot be modified.

In order to solve this problem, some people choose to replace the supported wireless network card, but there is no need to replace the wireless network card. The solution is as follows:

Open the Explorer menu, Tools-Folder Options-Display, remove the check mark before the option "Hide protected operating system files", open the root directory of drive C, right-click the file attribute of boot.ini, and remove the read-only attribute. 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, enter the device manager and see that the wireless network card has been enabled!

The driver in WIN7 X64 system needs digital signature, otherwise it can't be used normally. But sometimes it is necessary to use a driver without digital signature, but the driver cannot be used after normal installation. At this time, we can only use the driver after pressing F8 to enter the system in the mode of "disabling driver signature enforcement" at startup.

At present, there is no perfect solution to this problem, and it can only cure the symptoms, not the root cause:

Temporary solution: run, input: bcdedit/set test signing on enter.

Then restart.

You can turn off forced digital signatures.

However, there will be a prompt watermark after booting to the desktop, but there is no substantial inconvenience in use.
