Some of the Keys needs Admin Priv.
Are you deleting HKLM*…

Try this

void DeleteWithinKey(HKEY hKey) {

DWORD vlen, typ;
int rv;
TCHAR name[256];

do{
vlen = sizeof(name);
rv = RegEnumValue(hKey, 0, name, &vlen, 0, &typ, NULL, NULL);
if(rv == ERROR_SUCCESS) {
RegDeleteValue(hKey,name);
}
} while(rv == ERROR_SUCCESS);

for(;:wink: {

vlen = sizeof(name);
rv = RegEnumKeyEx(hKey,0,name,&vlen, 0,NULL,NULL,NULL);
if(rv != ERROR_SUCCESS) break;
HKEY h;
rv = RegOpenKeyEx(hKey,name,0, KEY_ALL_ACCESS,&h);
if(rv == ERROR_SUCCESS) {
DeleteWithinKey(h);
RegCloseKey(h);
}
RegDeleteKey(hKey,name);
}

}; // end DeleteWithinKey

Win9x would let you just delete the high key and it does the enumeration,
but NT based systems require you to go ‘down’ to each level and delete it
yourself.
