How to Fix High CPU Usage by CSISYNCCLIENT.EXE

If, after running for a considerable amount of time, your Windows computer starts becoming sluggish, often to the point where it becomes downright unusable, there is a good chance that a process running on your computer has gone astray and started using insane amounts of the computer’s resources – resources such as CPU. A process that is pretty notorious for causing this issue is the CSISYNCCLIENT.EXE process. The CSISYNCCLIENT.EXE process is associated with Microsoft Office 2013, and if something goes wrong with it, it has a tendency to start sucking up CPU resources and not letting them go, resulting in the affected computer becoming extremely slow and lagging.

If the CSISYNCCLIENT.EXE process is using an insanely large amount of CPU on your computer and causing your computer to grind to a halt, the following are the most effective solutions that you can use to try and fix the problem:

Solution 1: Install any and all available Windows updates for your computer

  1. If you are using Windows 7, open the Start Menu, search for “windows update”, click on the search result titled Windows Update and click on Check for updates when Windows Update If you are using Windows 8, 8.1 or 10, open the Start Menu, click on Settings, click on Update & security, click on Windows Update in the left pane and click on Check for updates in the right pane.

Solution 2: Perform a System Restore

If installing all available Windows updates for your computer does not work or if there are simply no Windows updates available for your computer, you can also try and fix this issue by performing a System Restore and restoring your computer to a point in time before it was affected by this problem. However, it should be noted that this solution is only going to work if a system restore point was created before your computer started suffering from this problem and that all applications and updates installed on your computer after the system restore point in question was created will be uninstalled during the System Restore. In order to perform a System Restore on a Windows computer, you need to:

  1. Press the Windows Logo key + R to open a Run
  2. Type rstrui.exe into the Run dialog and press Enter to launch the System Restore utility.
  3. Click on Next. If System Restore recommends that you restore your computer to an automatically chosen restore point on this screen, select the Choose a different restore point option and then click on Next.
  4. Click on your desired restore point from the list provided to select it, and then click on Next. Be sure to select a restore point that was created well before the weird circle showed up on your Desktop.
  5. On the Confirm your restore point screen, click on Finish.
  6. Click on Yes in the dialog box that pops up to begin the System Restore.

Windows will restart and begin restoring the computer to the chosen restore point. The process may take a significant amount of time, so just be patient and, once the process is complete and the computer boots up, check to see whether or not issue has been resolved.
