Hello, here are the answers to your questions:
The self-healing function is a very useful feature in the Win7 system.
First, we need to open the cmd command prompt window.
Click "Start" and enter "cmd" in the command bar to confirm.
2. After entering the cmd command prompt window, enter the command "sfc/?" and press the enter key. This way we can see all the commands for this inspector.
3. We choose to enter "sfc/verifyonly", so that the system will automatically perform "Scan the integrity of all protected system files. No repair work will be performed." This may take some time to execute, so you need to be patient.
4. After the scan is completed, the system will prompt "Windows Resource Protection found an integrity conflict." The normal result of my computer is that no integrity conflict was found.
5. If there is a problem, follow the prompts to check it out.
The next step is to enter "sfc/scannow" in the command prompt and press the enter key, so that the system will automatically perform the repair work. After the repair is completed, restart the computer - if it helps, please adopt it. .
