Problem: Open and explorer are greyed out when you right click on the start button

This is a bug (feature?) of windows 98 and 95.
It is caused by having one or more drives hidden in my computer.
You need to go to Tweak UI's my computer tab and be sure that the check boxes for ALL drives are checked, even if the drive is not installed on your system.
Click OK or Apply to save any changes.
You might have to restart your computer to see any changes.

It is one of the power toys from microsoft.
