Windows XP 掃描器與數位相機 掃描很慢

從純淨的系統 %systemroot%\system32 複製如下動態函式庫並擺入此機 %systemroot%\system32

regsvr32  wiadefui.dll
regsvr32  wiadss.dll
regsvr32  wiavusd.dll
regsvr32  wiascr.dll
regsvr32  wiaservc.dll
regsvr32  wiashext.dll
regsvr32   wiavideo.dll
regsvr32   camocx.dll

接著重新註冊函式庫

Start -> Run -> cmd

regsvr32  wiadefui.dll
regsvr32  wiadss.dll
regsvr32  wiavusd.dll
regsvr32  wiascr.dll
regsvr32  wiaservc.dll
regsvr32  wiashext.dll
regsvr32   wiavideo.dll
regsvr32   camocx.dll

或是直接整個系統修復

Start -> Run -> sfc /scannow
