VirtualBox Error Solution “Unable to load R3 module”

When starting the virtual machine in VirtualBox, I noticed an error of the following content:

Failed to open session for virtual machine MACHINE NAME.
Unable to load R3 module C:\Program Files\Oracle\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR).
Result Dode: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

This error occurs when Windows files are patched by the Universal Theme Patcher utility.
In this case, we are interested in the system file C: /Windows/system32/uxtheme.dll

You can almost always restore it by running the following command on the Windows command line as administrator:

sfc /scannow

This command will scan the system files and restore them if possible. Information about the execution process will be written to the file C:\Windows\Logs\CBS\CBS.log.
If the file cannot be restored with the command, then it can be restored from the installation disk.

After recovery, the error will not be displayed.
