What should I do if Win10 prompts that the requested changes cannot be completed?

Problem description:

When we installed telnet on the computer, we encountered a situation where it could not be installed and prompted that windows could not complete the requested changes. As shown in the figure below:

The solution is as follows:

1. Press the "Win R" key combination to open the run, enter "services.msc", and return Car and open the service;

2. Find the "windows installer" service in the service list and make sure that the service is started. If it is not started, we need to start it;

3. Next, right-click on the Start menu, find "Command Prompt", right-click and select [Run as administrator];

4. Execute the sfc /scannow command and press Enter;

5. Wait for the automatic scanning and repair of system files to complete, restart the win10 system, now Telnet can be installed.
