upadates downloaded, forgot to install, need to install updates manually, help req


After factory reset on laptop, I spent some time downloading over 100 updates from Microsoft. After which I shut the laptop down using "install later, shut down for now" thinking I could do the installs of the updates later. Much later, when I did shut down and install, I noticed only 13 installs, is that normal, shouldn't there have been over a 100,? Microsoft security center said they were over 100 updates ready for install.

I'd like to know which folder Microsoft security center stored the 100 plus updates so I can manually install them. What and where should I look?

Thank you in advance
