I had a problem with DVD Shrink slowing right down during decoding. I had a play with everything including cleaning up my PC, nothing i did worked. Finally in desperation I went to "Help & Support" on my PC , then to "Pick a Task", then to "Undo changes to your PC with Systems Restore" I selected a point 2 days previously.... BINGO !... it works very fast again ! As I do not understand PCs very well, indeed, not very much at all, I have over a long period of time used this "Systems Restore' when I have had PC problems, and I have, over a long period of time, it has fixed lots problem. Has anyone else had any experiences with this ?
