My university offers 1TB of free storage with Onedrive for Business, which sounded great for syncing all my photos and files. Unfortunately, after installing Onedrive my computer became unusable, the CPU was constantly running between 30-40% usage with Onedrive the Microsoft Search Index taking over the machine. I’ve searched long and hard for a solution, and a series of steps finally did the trick:
- Download and install a fresh new copy of Onedrive for Business
- Run the Onedrive Troubleshooter to make sure there are no issues
- Clear the office cache.
For that last step, follow the instructions from “Why is OneDrive for Business always using 25% CPU?” :
1. Right click on the Windows status bar, select Start Task Manager, and get a list of running processes as follows:
- If you’re running Windows 7: Select the Processes tab.
- If you’re running Windows 8: Select More Details in the bottom left and then select the Details tab.
2. Verify that none of the following processes are running:
3. If any of the processes above are running, stop the process by right-clicking it and selecting End Process.
4. Give yourself an administrator role as follows:
- If you’re running Windows 7: Click the start button and type cmd in the search bar. When cmd.exe appears in the results, right-click it and select Run as Administrator.
- If you’re running Windows 8: Drag your mouse to the bottom left corner of the screen, right click on the Start icon that appears, and then select Command Prompt (Admin).
5. At the command prompt, delete the Office file cache and Spw folders by issuing four commands as follows:
a. Type this and then press the Enter key:
1 cd %USERPROFILE%AppDataLocalMicrosoftOffice15.0
b. Type this and then press the Enter key:
1 rmdir OfficeFileCache /s
c. Type this and then press the Enter key:
1 cd %USERPROFILE%AppDataLocalMicrosoftOffice
d. Type this and then press the Enter key:
1 rmdir Spw /s
6. If you get an error when executing either rmdir command (steps b or d), one of the .exe processes is probably still running. Fix the problem by returning to the Task Manager (step 2), stopping the processes, and then removing the directories as described previously.
7. Remove the excess folders or files from your local SkyDrive Pro folder, and add them in smaller groups, according to the guidance at the top of this table.
Hope that helps. Good luck.
