@ Venths : that isnt anything close to the problem... the programs apart form new ones, dont show.
This problem may occur if the uninstaller for a program incorrectly removes registry entries that are used by Windows and the Add/Remove Programs tool.
Try system restore first. If no progress, click start, type REGSVR32 APPWIZ.CPL and click ok. Any error message? Newly installed program can be displayed fine, that means the file APPWIZ.CPL should be fine.
If you would like to remove the program from add\remove program, you can download the Windows cleanup utility
Cant restore, problem is more then 1 month old! so i tried: REGSVR32 APPWIZ.CPL , in which i get an error.
ask for screen if you wish. and cleanup utility gives error.
