win10電腦麥克風沒反應 收不到音

某台asus win10的筆電內建麥克風跟外接耳麥，都收不到音。

但在裝置管理員裡都有找到設備，所以就更新驅動，結果還是沒用。

後來拿閒置硬碟換上去裝了win11後，居然都沒問題，那表示硬體沒故障。

在換回win10 後，突然想到，去設定裡面看看，結果發現在"隱私權"裡面有一個"麥克風"的設定，有一個"存取此裝置的麥克風"居然是關閉的，改成開啟後，麥克風就正常了。

An ASUS laptop running Windows 10 had issues with both the built-in microphone and external headset not picking up any sound. Even though the devices were detected in the Device Manager, updating the drivers didn't solve the problem.

Later, when a spare hard drive was installed and Windows 11 was installed on it, surprisingly, there were no issues with the microphone. This suggested that there was no hardware fault.

Upon reverting back to Windows 10, checked the settings. It was discovered that under "Privacy," there was a setting for "Microphone," and the option to "Allow apps to access your microphone" was inexplicably turned off. After toggling it on, the microphone started working properly again.

所有網路共用資料夾都連不上 錯誤代碼:0x80004005

 有台win7電腦有時後會突然連不到所有的共用資料夾都連不上 ，錯誤代碼都是0x80004005。

但上網都正常，去ping那些共用資料夾的主機也正常。

經查才發現，那個win7電腦的網卡內容裡，少了很多項目，正常的應該要像下圖一樣，但那台電腦裡的網卡內容只剩ipv4的設定。

要把其他功能找回來，就只要按下左下方的"安裝"，裡面就有其他項目可以選，選好後馬上就會裝回來了，但是要重開機後，會生效。

Sometimes a Windows 7 computer suddenly cannot connect to any shared folders, and the error code is always 0x80004005.

However, internet browsing works fine, and pinging the hosts of those shared folders also works.

Upon investigation, it was found that many items were missing from the network card settings of that Windows 7 computer. Normally, it should look like the image below, but the network card settings on that computer only have IPv4 configuration.

To restore the missing functionality, simply click on "Install" at the bottom left, where there are other items to select. After selecting the desired items, they will be installed immediately, but a reboot is required for the changes to take effect.
