Deactivate virus scanner

If you receive the error code 803D000A when calling up the Windows updates, you should briefly deactivate your virus scanner and possibly the firewall . Both systems can negatively influence the Windows update process and be the cause of the problem. Of course, you should not forget to reactivate the antivirus software as well as the firewall software after the successful installation.

Register BITS again

There may also be a problem with BITS , the Background Intelligent Transfer Service , which is responsible for getting and installing the Windows updates. The Windows service “ Bits ” includes some DLLs that you should register again. The following commands are necessary for this.

regsvr32 qmgr.dll
regsvr32 qmgrprxy.dll
