The 'Date modified' column in Programs and Features window is empty

Question

I am definitely sure; I was able to sort installed applications by install date-time.

But now the only column is Date modified, and it is empty.

How do I fill this column?

Answer 1

Right-click the row with the headings on it, select "More...", and then deselect "Date Modified". Right-click the row again, select "More..." and select "Installed On"
