Start the assistant as an administrator

If you are having trouble installing Windows 10 version 1803, here is what you could do to make it easier. You must run the installation assistant with administrative privileges. This is easy to do.

  1. Go into the Start Menu and type “Windows Update”.
  2. Click on the option “Change Settings…” and select “Administrative Templates.”
  3. Scroll down to the section labeled “User Account Control,” and check off the box next to “Turn User Account Control On or Off.”
  4. Then, scroll down to the bottom and find the section titled “Installer.”
  5. Check off the box next to the words “Allow the following programs to be installed without confirmation.”
  6. Finally, click OK. Now, restart your computer and try again.

Update the graphics drives

When you install Windows 10, it automatically installs the most recent version of Microsoft DirectX, which includes the latest graphics driver. However, if you do not update your graphics driver regularly, the performance of your PC could suffer.

The best way to ensure that your graphics card is working well is to use the manufacturer’s website to download the latest graphics driver. This ensures that you are getting the most up-to-date software.

If you decide to manually download the latest graphics driver, make sure that you check the compatibility list before downloading. You can also try updating your graphics driver using Device Manager. You might also consider upgrading your graphics card.

Turn off the antivirus

Disabling your antivirus is one of the easiest ways to install Windows 11 without worrying about any errors popping up. Most antivirus programs offer some sort of temporarily disabled feature.

You should turn off your antivirus when you are installing Windows 10 because this step is required by the installer. If you have multiple antivirus programs running at the same time, you may need to temporarily disable them in order to complete the installation.

Disable your firewall

Your firewall protects your computer from harmful websites and malware. It can also block certain features of Windows 10. Disabling your firewall allows the installer to work more efficiently.

To disable your firewall:

  1. Open the Start menu and search for “firewall.”
  2. Right-click on the Firewall icon and choose Properties.
  3. Uncheck the box next to Enable firewalls.
  4. Restart your computer.

Turn On the user account control

User Account Control (UAC) is an operating system security feature that prevents unauthorized changes to computer settings. This article explains how to enable UAC in Windows 10.

To turn on UAC:

  1. Open the Start Menu and search for “user accounts.”
  2. Select Change User Account Control settings.
  3. On the left side of the window, click on the Advanced tab.
  4. Under the Security heading, uncheck the boxes next to Turn off User Account Control and Do Not Allow apps to change my screen resolution.
  5. Click OK.
  6. Reboot your computer.

Set the compatibility mode for Windows

Microsoft offers an installer for Windows 7 or 8 that should work without problems, but some users are reporting that they cannot install Windows 10. In fact, some people even report that they had no trouble installing Windows 10, while others say that they could not complete the process because they encountered errors. This issue seems to affect Windows 10 installations on computers that run on older versions of Windows.

Make sure you select the correct Windows version before running the installation assistant, otherwise you might end up with a system that does not boot properly. If you still experience issues after following these steps and trying to uninstall and reinstall Windows, make sure you set the compatibility mode correctly. Under the heading “Choose Your Options”, choose the option labeled “Advanced Startup Options”. Then under the “Recovery” section, choose “Go Back to Previous Version”.

In both cases, you must restart the computer. There you’ll find a list of compatible modes for each operating system. Click on the “Change settings for my device…” button and select the mode that best suits your needs.

Reboot your computer

If you’re having trouble getting your computer to boot up properly, it might be because of an update or driver. If restarting doesn’t fix the problem, there are other things you can try updating your drivers manually or with the help of a third-party driver updater.
