Hi, good day!
If the Advanced Micro Devices, Inc. – Display driver update disappeared after you restarted your PC, it most likely means the update was completed.
To confirm, you can check Device Manager > Display adapters and see if your AMD graphics adapter is listed normally. You can also right-click it, select Properties > Driver, and check the Driver Version and Driver Date.
For the Windows Update location, try opening Settings and looking at the left-hand menu. Windows Update should be near the bottom. If it is not there, you can press Windows key + R to open Run, type:
ms-settings:windowsupdate
Press Enter.
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
