What to do if I failed to install security updates since Dec 2025?

So back in December the security update KB5072033 failed to install in my computer repeatedly. The update was said to force AppXSVC to autorun and eat up RAM, which causes lags that I don't want to happen, so I was waiting for further updates to change this.  Now I'm hearing news that not installing that previous update will make the computer unstable, and will malfunction if I install the January update KB5074109.  So what am I supposed to do now? Wait for future updates to fix this? Try to install KB5072033 again?
