Change/Remove button in my Add/Remove programs window is gone

To fix it (manual method -safe method-):
Open you registry editor (Start > Run > REGEDIT)
In the registry editor, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\software name
In the right window, remove the key value NoRemove and NoModify.NoRemove set to 1 means that the remove button will not be shown.NoModify set to 1 means that change button will not be shown.
Do the above two steps (2 and 3) for each and every software listed under ...\Uninstall\.(this can take a while indeed)

After finishing, navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\software nameand repeat the whole process.
When both those registry keys are done, restart (or update by pressing F5) your "add/remove programs" panel.
