PHP doesn't accept upload dir in ini file

[netmastan]

I have changed the upload directory settings in php.in file as I could not upload anything .MY uploading script gives error "File 'c:windowsphp16.tmp' not found (Errcode: 2)"

; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
upload_tmp_dir =c:/windows/temp
