Ahh, this guy didn't get the memo. With modern Windows you're just temporarily borrowing the computer, but Microsoft is in charge of it. They decide what programs you can run, which folders you can look in, which files you can delete and yes, they decide when it updates, even if you're in the middle of something important.
How can you be sure about this? They patch and update the telemetry code frequently, for example, when they updated it to get around hostfile blocking, or moved their servers to new addresses for the same reason. The Windows 10 upgrade assistant that was installed without warning on Windows 7 included telemetry that regularly scanned all the executables on your drives and sent the list to Microsoft (ostensibly to check for compatibility, but I'm sure they kept the data around). If you can't trust the OS and they can update it at will, you have no hope of privacy.
