Semaphore Timeout Period Has Expired Error In Windows 10

When you are trying to copy a large file from one location to another you might have experienced an error that reads “The semaphore timeout period has expired error (0x80070079)”. This can happen when transferring the file from within your computer or to a different computer connected to the network. In this latest installment of our troubleshooting series we will show you how to fix this problem.

Fixing the error 0x80070079 semaphore timeout period has expired

Before performing any of the recommended troubleshooting steps listed below it’s best to restart your computer and router first. This action refreshes the operating system and remove any corrupt temporary data that could be causing the problem.

Perform a clean boot

To eliminate the possibility of a non-windows service or a software installed in your computer causing the problem you will need to do a clean boot.

  • Type msconfig in the search bar and open the System Configuration app that appears.

  • Click Services.

  • Click the checkbox next to Hide all Microsoft services.

  • Click Disable all.

  • Click Startup.

  • Click Open Task Manager.

  • Click any startup program you suspect might be interfering.

  • Click Disable. Repeat steps 9 and 10 for all startup programs.

  • Click the X to close Task Manager.

  • Click OK in the System Configuration window.

  • Restart your PC.

When your computer restarts only the essential services will be loaded. If the semaphore timeout period has expired error still occurs then the problem isn’t caused by a service or software. However, if the issue does not occur then you will need to find out what service or software is causing the problem.

The best procedure is to repeat steps 1-5 above, but re-enable half of the services. Re-enable the top half of all non-Microsoft services then restart your computer. Test to see if the issue still occurs. If it doesn’t then repeat steps 1-5 again, but this time re-enable the bottom half of all non-Microsoft services instead. Restart your PC, and check if the issue occurs. Start to narrow down the search. Keep unchecking services and restarting your PC. Once you find that the issue is gone, you should be able to find the culprit.

Once you are ready to boot your computer normally follow the steps listed below.

  • Type msconfig in the search bar and open the System Configuration app that appears.

  • Click Services.

  • Click the checkbox next to Hide all Microsoft services.

  • Click Enable all.

  • Click the checkbox next to the offending startup service.

  • Click Startup.

  • Click Open Task Manager.

  • Click a startup program.

  • Click Enable. Repeat this for all startup programs.

  • Click the X to close Task Manager.

  • Click OK in the System Configuration window.

  • Click Restart.

Make sure the drive uses an NTFS format

If the problem occurs while transferring data to a USB flash drive then you should make sure to convert this drive from FAT32 to NTFS. FAT32 can only accommodate a file of up to 4GB in size while NTFS has a maximum file size of 16TB.

  • Connect your portable drive with your computer

  • Right click on the drive and select Properties

  • Check the file system of the drive. If it FAT32 then click Cancel

  • Right click on the drive and select Format…

  • Select NTFS from the drop down menu under File System

  • Click Start and wait for it to finish

Check if the error code 0x80070079 still occurs.

Update your network drivers

  • Click the arrow on the left side of Network Adapters

  • Right click the wireless adapter and select Properties

  • When prompted, choose Search automatically for updated driver software.
