Stuck with Microsoft.
Suppose you inherited a PC or acquired a laptop, but it only runs Microsoft software and for any number of complex reasons you can’t change that. What would you do?
How would you make a Microsoft based system somewhat friendlier?
Obviously my answer would normally be to install Linux, but I will try to help out those stuck with Microsoft as their main operating system.
Firstly, install AVG’s free edition and scan the machine immediately.
If I had to use a spreadsheet and wanted only free software on the machine then Openoffice is the choice.
Finally, I would think about installing K Lite’s Codec Pack.
All of that won’t turn a Microsoft dog’s breakfast into something wonderful, but it should be less hard work, if you are lucky.
