Hello
Thank you for your question and reaching out. I can understand you are having query related to Windows update.
UPDATE. EXE is a legitimate executable file developed by Microsoft Corporation. This process is known as Windows Service Pack Setup and it belongs to the software Windows Operating System. It is commonly stored in C:\Program Files
If the updates are not getting installed automatically then I will suggest you check if there is any Group policy or Local Policy or any Third party installed for Windows Updates.
Additionally , Please check Windows event logs also during the Update schedule time.
