Defective cord
In the event that changing the USB ports did not help and the message "unknown error 2003" appears again, it is worth trying to replace the charging cable. In most cases, he is the source of the problem.
Reinstall software
If all the above methods did not help or if there is no way to replace the cable, you should try reinstalling iTunes on your computer. To do this, carry out the following steps:
- In the "Windows Settings" program window, go to the "Applications" section.

Virus threat elimination
It may happen that the installation file was downloaded from an unverified site. In this regard, a virus got onto the computer. It is worth noting that the use of standard antiviruses is not always effective. This is due to the fact that many malicious programs disguise themselves as system files and go unnoticed.
For example, Kaspersky Anti-Virus and Windows Defender often do not skip verified files for downloading and installing, while not noticing passing viruses. The solution to the problem may be the installation of special software that periodically scans the system. As an option - Emsisoft Anti-Malware.
Registry Recovery
Another way to resolve the 2003 error may be to take steps to restore the registry.
ATTENTION! Do not try to fix this problem yourself. Erroneous data changes can lead to disruption of the system or its complete failure. It is better to entrust this business to professionals.
However, you can try using automatic registry repair programs. One such example is WinThruster. Its task is to scan the computer with the subsequent removal of damaged files that impede the stable operation of programs, as well as fixing the 2003 error.
With the right settings, the utility can have a positive impact on the level of performance. It is also worth noting that its tasks include maintaining a backup copy of the data, which can prevent disruptions in the operation of the smartphone operating system.
Cleaning obsolete and malicious files
Another useful step is to clean the disks of various files left over from already deleted programs. The so-called defragmentation. You can do this without third-party software. It is enough to execute the following algorithm:
- activate the Run program by pressing the key combination Win and R;
- in the window that opens, enter cleanmgr;
- in the submenu that appears, select the disk that you want to clean.
Another option is to use the Revo Uninstaller program. To clean the disk from unnecessary files, you must:
- in the upper panel of the program activate the item "Tools";
- in the list that appears, select a line called "Cleaner of unnecessary files", a transition to a new tab will occur;
- on the right side of the program there will be a list of disks connected to the computer, and above them the button "Select folder";
- after clicking on it, a window will open in which you need to mark the directory necessary for cleaning, you can immediately scan the whole disk;
- after selecting the desired folder, you need to confirm the operation and click the "Scan" button located above the tab bar;
- after that, the program examines the necessary folder and displays a list of files that can be deleted;
- Now you need to click the "Delete" button next to it;
- the selected directory will be cleared.
System driver update
This procedure will be useful in any case. Over time, older drivers slow down the system and are unable to interact normally with modern programs. In this connection, there is a compatibility conflict, which may lead to the occurrence of error 2003. In order to safely and comfortably update the drivers of all programs and devices on the computer, it is recommended to use the Microsoft DriverDoc utility.
Restore windows
This 2003 error correction option can be used only when none of the above resolved the problem. Perhaps the situation is due to errors that occurred during the system update.
To perform this operation, you need to go to the control panel and enter "Recovery" in the search. A window opens with various options for restoring a previous version of Windows. You can also install past updates to the Windiws 10 operating system through the update and security menus.
Complete reinstallation of the system
Even if the rollback to the previous version of Windows updates did not bring any results, it remains only to completely demolish the current system. The reason for this may be the active operation of the virus, which not only affected iTunes data, but could also harm the entire operating system.
