與(yu)很多(duo)系(xi)(xi)統(tong)(tong)(tong)軟(ruan)件(jian)不同，系(xi)(xi)統(tong)(tong)(tong)工具(ju)(ju)并不是系(xi)(xi)統(tong)(tong)(tong)自(zi)帶(dai)的(de)軟(ruan)件(jian)，而是經過公司生產(chan)包裝，根據需(xu)求制作的(de)適用于(yu)一(yi)類系(xi)(xi)統(tong)(tong)(tong)的(de)軟(ruan)件(jian)。顧名思義，與(yu)系(xi)(xi)統(tong)(tong)(tong)軟(ruan)件(jian)類似，系(xi)(xi)統(tong)(tong)(tong)工具(ju)(ju)作用于(yu)系(xi)(xi)統(tong)(tong)(tong)，常見作用有系(xi)(xi)統(tong)(tong)(tong)優(you)化(磁(ci)盤(pan)的(de)分區、磁(ci)盤(pan)的(de)清理(li)、磁(ci)盤(pan)碎片整理(li)等)，系(xi)(xi)統(tong)(tong)(tong)管理(li)(驅(qu)動等)，以及系(xi)(xi)統(tong)(tong)(tong)還原(yuan)等。

壁(bi)紙桌面通常(chang)也被稱之為圖(tu)片(pian)，待機圖(tu)片(pian)，屏(ping)保圖(tu)片(pian)。用(yong)戶只需下載自己(ji)喜歡的(de)(de)圖(tu)片(pian)，圖(tu)片(pian)的(de)(de)分辨率(lv)和自己(ji)的(de)(de)手(shou)機屏(ping)幕的(de)(de)分辨率(lv)相對應，就可以通過手(shou)機設置為桌面壁(bi)紙了。不同的(de)(de)操作系統有不同的(de)(de)設置方式(shi)，操作系統可以設置動(dong)態更(geng)換(huan)的(de)(de)壁(bi)紙，每隔(ge)設定的(de)(de)時間壁(bi)紙就是變換(huan)，也增加了手(shou)機使(shi)用(yong)的(de)(de)樂趣(qu)。
