之前為了想把手機畫面直接投影到電視上，買了Terzomen AirLink，快要1900元。
最近又買了小米盒子3，比較一下差別。
Terzomen AirLink
優點:不用特別設定，接上去就可以用了。
缺點:居然只支援apple的產品，android的手機/平板都不支援。
接在手機那端的連結器看久還蠻燙的。
單純就是無線傳輸影像的功能，一定要搭配手機或電腦用。
比較貴。
優點:apple跟android的設備都支援手機投影。
不需要手機也有一些串流app可以看片。
比較便宜。
缺點:一開始設定有點難用。
需要有wifi。
相比之下，配合自己使用的環境，用小米盒子就夠了。
outlook 郵件清單，除了寄件人，主旨，時間之類的，還會在下一行顯示部分的郵件內容，
讓整個郵件清單看起來很雜。
可以在檢視的功能表中，在訊息預覽裡面，選擇關閉，就不會顯示那一行郵件內容了。

In the Outlook mail list, in addition to the sender, subject, and time, part of the email content is also displayed on the next line,
which makes the entire mail list look cluttered.
You can go to the View tab and, under Message Preview, select Off to stop showing that line of email content.
同一個M365帳號，在兩台電腦上都設定的outlook，但設定的底色不同，結果兩台電腦上的outlook底色都會一直亂跳。
是因為outlook設定，有一個"將我的outlook設定儲存在雲端中"被打勾了，所以兩台電腦的outlook設定會互相影響，只要把這個設定取消就恢復正常了。
The same M365 account was configured in Outlook on two different computers, but each had a different theme color. As a result, the background color in Outlook kept switching back and forth on both computers.
This happened because the Outlook setting "Store my Outlook settings in the cloud" was enabled, causing the settings on one computer to affect the other. Simply unchecking this option resolved the issue.
在WINDOWS2019下載windows 的更新檔要進行安裝，但執行後都沒任何反應，或是要等很久才會跳出smart screnn的警告視窗。
這是因為系統設定中，有做安全性控管，設成警告。
只要先把它調成關閉，重新登入一次系統，這時後在點選安裝，視窗就會正常跳出，讓我們點進下一步進行安裝。
有一份excel編輯到一半時當掉了，重開啟啟後，裡面完全沒任何東西，沒任何頁籤。
所以就用修復的方式再開啟一次，但還是沒效，想說沒救了。
結果就查了一下excel沒有任何頁籤，沒想到還真的有這個設定，去檢視裡面，取消隱藏頁籤，檔案裡的資料就全部出現，恢復正常了。
偶爾都會遇到ad帳號一直被鎖的問題，就要去查明原因，下面就列出清查的方式。
事情準備 : dc主機上相關log功能一定要開。
1. 在gpo->domain controllers policy裡，要啟用下列三個稽核功能，這樣在事件檢視器裡的安全性事件裡，才能找到登入失敗的相關訊息。
We occasionally encounter issues where an AD account keeps getting locked, and we need to investigate the cause. Below are the steps for troubleshooting.
Preparation:
Make sure the relevant logging features are enabled on the domain controller (DC).
In GPO -> Domain Controllers Policy, enable the following three audit policies. This will allow you to find failed login information under the Security events in Event Viewer.
Also in GPO -> Domain Controllers Policy, enable NTLM auditing. This helps you locate more accurate failed login details under the NTLM section in Event Viewer.
Configure alerts to notify relevant personnel via email when an account lockout log is generated. This ensures you're aware when an account is repeatedly getting locked.
Troubleshooting Process:
When you discover that a certain account keeps getting locked:
First, check the Security event logs for event IDs 4625, 4771, and 4776. If you can find the source IP there, locate the corresponding computer and take action.
If the source computer cannot be identified in the Security logs, check the NTLM logs. These also show the source machine involved in the failed login.
A recent unusual case:
An account from domain A was being locked, but the NTLM log showed that the secure channel name was a domain controller from trusted domain B. However, the workstation name shown could not be found in domain B and kept changing.
In this case, we checked the NTLM logs on the domain controller in domain B. The secure channel name in the logs pointed to a computer within the domain.
We later found that this computer was running a public-facing service, and there were some abnormal external connection attempts. After shutting down the service, the account lockout issue was resolved.
如果要查詢m365 office 帳號在哪一台設備啟用了，就要先進到Microsoft 365 admin center。
在"作用中的使用者"，點選該帳號，左邊會出現相關資訊，在最下面就有一個"檢視 Microsoft 365 啟用"。
裡面就會顯示在哪些裝置上啟用了這個帳號。
利用Next Terminal， 遠端連線到其他台windows電腦時，按某些鍵時，並不會出現正確的字，會變成其他快捷鍵功能。譬如說按下t，會跳出檔案總管之類的。
這時後就是把那台windows重開機，就會正常了。
最近Fortigate 升級firmware後，某些win7在使用sslvpn連線都會出現 mismatch in the TLS version的錯誤。
After upgrading the Fortigate firmware, we observed that some Windows 7 systems encountered a "mismatch in the TLS version" error when attempting to connect via SSL VPN.
We verified that all TLS-related options were enabled under Internet Options, but the issue persisted.
Upon further investigation, we discovered that the problem was caused by missing Windows Updates on the affected Windows 7 machines.
However, we were unable to determine exactly which specific update resolved the issue, as we did not test each update individually. Instead, after applying all pending Windows Updates, the SSL VPN connection was successfully established.
照著下列這編要做PYTHON發訊息到telegram(https://vocus.cc/article/67ca97aefd8978000187e654)，
結果出訊錯誤訊自 "{'ok': False, 'error_code': 400, 'description': 'Bad Request: chat not found'}"
原來是你要先在telegram搜尋到自己剛建立的bot，傳個訊息給它，才可以用python發訊息給它。
