The fear of software upgrades

The other day, as I was going through yet another software upgrade I realized that I was tense. On thinking about it, I realized that if all went well, I would have spent ten to fifteen minutes watching my computer whirr, and if all went well the software would work much as it did before. Perhaps it would have a few more features, but since I really did not know I needed them, the benefit would be marginal. On the other hand, there was a modest risk that it would not work, or interfere with other software, or require updating other elements. The times when the upgrade sticks in our memories are the times when it is a problem. So software upgrades are more dreaded than anticipated eagerly.
