well..i did a change in explorer.exe file to make changes in the text displayed on the start button at talkbar. i have done this using a software that could open the explorer file but the text start still not been changed.
i am sorry because i am not sure that wheather this issue started before or after the explorer.exe file edited.
what all i did is,
1 opened explorer.exe using restHacker software
2 expanded string and then string table then 38 then 1033
3 changed text start to Innocent.
4 file->save as->explorerinnocent.exe
5 opened registry editor
6 HKEY_LOCAL_MACHINE->software->microsoft->windows NT->current virsion
7 then made a string named shell and assined value explorerinnocent.exe to it.
all this procedure is explaned over a site.
