Article Introduction：1. Solve the problem of configuration progress when opening Office? When you open Office software (such as Word, Excel, etc.), sometimes the configuration progress will be displayed. This may be caused by the following reasons: Solution: 1. Interrupting the configuration process: Sometimes, an accident occurs when closing the Office application before, causing the configuration information to not be saved correctly. In the configuration progress window that pops up, try to cancel or interrupt the process. Next, try to reopen the Office application and observe whether the configuration progress problem still occurs. 2. Repair Office installation: It may be that the Office software installation file is damaged or some files are missing, causing configuration progress problems. Try using Office repair
