共用打印機要開內置的 Windows Firewall Service
昨天初時設定共用打印機時出現錯誤,原來提供共用設備要開 Windows 內置的 Windows Firewall Service,一向是用 Comodo 做防火牆而沒有開啟 Windows Firewall,開啟 Windows Firewall 服務後便沒問題了。

解決光碟及記憶咭不能自動播放的問題
之前才說可以嘗試以兼容模式安裝舊程式,但今天安裝舊版 ACDSee 時就出現問題,ACDSee 的裝置偵測程式跟 Windows 7 內建的自動播放功能出現相撞,使光碟及記憶咭不能自動播放,就算不啟動裝置偵測程式,記憶咭也不能自動播放,最後在以下網站找到解決方法。

要留意的是記憶咭可能是因其他原因而不能自動播放,懶點省去翻譯就直接節錄上文提供其中的解決方法;
"4. Ensure that NoDriveTypeAutoRun and/or NoDriveAutoRun policy registry value data is correct
For most users, the main culprit of AutoPlay not functioning is NoDriveTypeAutoRun registry key, where its value has been modified unknowingly. Some third-party software program, especially disc imaging or image editing program such as Nero, PowerISO, MagicISO, and even some other application programs such as Rhapsody and VMWare virtualization products intentionally disable AutoPlay feature by changing system’s policy to avoid conflict with the program. The problem is after uninstalling the software, the AutoPlay feature does not re-enable or restore. User has to rely on trick below to re-enable the AutoPlay.
If you’re facing the drive won’t Auto Play or Auto Run issue after installing certain software, try to uninstall the software to see if it fixes the problem. Better still if it’s possible to roll back the system using System Restore to earlier Restore Point when the software is not yet installed.
NoDriveTypeAutoRun registry key is used by Group Policy to configure whether to disable the Autoplay feature on all drives of the type specified. To check this setting, run Registry Editor (regedit), and navigate to the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
or (note that above registry value, if exists, will always supersede the below user-specific key),
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
Locate the NoDriveTypeAutoRun registry entry on the right pane. The registry key is in DWORD hexadecimal value, which each bit determines which type of drive to disable or enable AutoPlay feature. There are many possible value for NoDriveTypeAutoRun, some possible NoDriveTypeAutoRun registry value data includes:
0×00000000 (0) enable all AutoPlay and AutoRun.
0×00000080 (128) disable AutoPlay on unknown reserved file type.
0×00000091 (145) default in Windows Vista and Windows 7.
0×00000095 (149) default in Windows XP.
0×000000B5 (181) disable AutoRun on CD-ROM drives, plus default unknown drive, removable drive (meant for floppy or ZIP), network drive and reserved drive type.
0×000000FF (255) disable AutoRun/AutoPlay on all drive types.
Thus, if the NoDriveTypeAutoRun registry value data is set to 0x000000B5 (181) or 0x000000FF (255), which disables AutoRun/AutoPlay on most or all drive types, the AutoPlay won't work when a drive is connected...."

以兼容模式安裝舊程式
轉了用 Windows 7 後,一些版本較舊原本只支援 XP 或 Vista 的程式可能會不能正常安裝執行,這時可以試試這個辦法。
右擊安裝檔,選擇"內容">"相容性">在相容模式下鈎選"以相容模式執行這個程式:">再選擇這個程式能支援的 Windows 版本>按"確定"後以正常方法進行安裝便可。

Acer/Benq 620UT Scanner Driver
今天要掃瞄一些文件,但網上就是找不到這部舊掃瞄器的 Win7/Vista 驅動,只好試一試用 XP 的,安裝後嘗試用 Mirascan 控制掃瞄器,但 Mirascan 因找不到掃瞄器而不能啟動,反而打開"裝置與印表機"見到裝置內已有 FlatbedScanner 13,雙擊這裝置便會打開 Windows 7 內置的掃瞄器控制視窗;
平常很少用掃瞄器,這樣簡單的控制介面便已足夠,可以省回點錢不用買新掃瞄器。
Acer/Benq 的驅動可在以下連結找到
官方下載網頁

禁止進入休眠及刪除 Hiberfil.sys
Windows 7 進入休眠時會把資料存入 Hiberfil.sys 以便回復時使用,但就算不在休眠狀態時 Hiberfil.sys 也會佔用硬盤記憶,若不需要休眠功能,可以用以下command line 指令禁止進入休眠及刪除 Hiberfil.sys 檔:
powercfg –h off
powercfg –h off

設定 Chrome 的 Cache 大小及位置
Chrome 的選項目錄內沒有 Cache 大小及位置的設訂,但卻可以在捷徑加入程式啟動參數 (startup switch) 設定,方法是如下在Chrome 捷徑的目標欄加入適當參數:
...chrome.exe --disk-cache-dir="CACHE_DIR" --disk-cache-size=N
--disk-cache-dir="CACHE_DIR": Cache 位置
--disk-cache-size=N: Cache 大小,N 是以 bytes為單位
...chrome.exe --disk-cache-dir="CACHE_DIR" --disk-cache-size=N
--disk-cache-dir="CACHE_DIR": Cache 位置
--disk-cache-size=N: Cache 大小,N 是以 bytes為單位

Chrome 預設香港字
Firefox 從 5.0 開始便不能預設香港字顯示網頁,雖然已經用回復功能反影,但 6.0 版似乎也不會解決這問題,Firefox 好像已放棄了香港用戶,既然這樣就不如試試 Chrome。
如IE一樣,Chrome 只要更改繁體中文學(BIG5)的顯示字型為"細明體HK_SCS"便可以預設繁中網頁用香港字顯示,不用每次人手改動。
試用了幾天,總的來說 Chrome 反應比 Firefox 快,無論是啟動或瀏覽都有比 Firefox 爽的感覺,要不是現在還找不到 Newsfox 的代用品,可能就不再用 Firefox 了。
但快不是轉用的主要原因,而是 Firefox 放棄了自己最大的優勢 - 高用戶自訂性。
