Do not recall downloading despite the fact that application states is created my Windows. Have deleted (or thought I did twice) but each time I have logged on I am asked if I want it to take control of my computer. Looking to delete it again and I cannot find it, despite fact that Windows says it is in C/. Read scathing reviews but none tells me exactly what to do. Computer had grown slow. I have used Norton Eraser and Microsoft Fixit, to no avail. Any ideas?> When i search computer for it, both regwork and regworkS appear.
