Hi ,
Please try to take following steps to manually replace a corrupted system file with a known good copy of the file. (You need to get a known good copy of the system file from another computer that is running the same version of Windows with your computer.)
Use the System File Checker tool to repair missing or corrupted system files
When there are multiple file problems detected on sfc /scannow that could not be fixed using the system update readiness tool often the best option is system restore.
In addition, please understand, windows 7 support has been ended on January 14, 2020. Technical assistance and software updates from Windows Update that help protect your PC are no longer available for the product. Microsoft strongly recommends that
you move to Windows 10 to avoid a situation where you need service or support that is no longer available.
