我嘗試升級 Foxit Reader，但它使目錄處於不可讀狀態。我無法查看該目錄，甚至無法刪除它，即使以管理員身份也無法。我該如何刪除它以便重新安裝？
C:\Program Files (x86)\Foxit Software>takeown /f "Foxit Reader"
ERROR: Access is denied.
C:\Program Files (x86)\Foxit Software>takeown /a /f "Foxit Reader"
ERROR: Access is denied.
C:\Program Files (x86)\Foxit Software>icacls "Foxit Reader" /setowner Administrator
Foxit Reader: Access is denied.

甚至運行了 chkdsk，也沒有發現問題：

問題是 Brother Control Center 鎖定了該檔案。我不知道為什麼 Brother Control Center 正在運行 - 我沒有運行它，它不會在啟動時啟動 - 但它有一個鎖。我殺了該進程，目錄消失了。我用「Process Explorer」找到了鎖，並蒐索了「Foxit Reader」。同一進程「BrCtrlCntr.exe」有兩個鎖定。
