After restarting the PC still remains at the previous version and says it needs to be restarted

I have seen this happen frequently with upgrades, if I go from an older version to a newer version, what happens is as follows.

I will see in the SEPM console that the PC needs to be restarted, I restart it, and it is still at the previous version and says it needs to be restarted. It's like Deja Vu. Sometimes it will tell me it needs to be restarted and it remains at the same version until I manually remove and re install it. It happens less and less now but I want it to not happen at all.
