I can not access the start buttons on the desktop and my TV is still running windows 8.1. Well, I have a Dell Optiplex 755 that I tried to install the latest drivers for windows 10, and I separated my desktop from the TV because I thought that the system was showing me the error but.now I can not see anything on my TV. If you do not insert your Windows Activation Key, the device drivers will be blacklisted. When you install Windows 10 you may see that it asks you to activate with a product key. If there is a newer chipset, you need newer driver.
For example, you may have windows 10 version 1709 or later, and have drivers for legacy Windows 7 or earlier. If there is not the same version of driver for the device and operating system, it will not work properly. This is what determines which device (controller) driver is used to install the Windows Os to the device. The most important thing is to make sure that the drivers for all connected device has the same driver version number as the Dell OptiPlex 755 device version. When it shows up you just have to double-click on it to launch device manager and click ok in the warning message that appears. When the device interfaces install the correct drivers for your Dell OptiPlex 755 it will appear in the device manager as a new device. Dell Pci Serial Port Driver Optiplex 755 >
