Solution about DNF automatically disappearing or compatibility with win7

I have encountered this problem either, just open the channel, or play it, it will disappear within 10 minutes, and it will not be dropped. Very tangled. Later, I searched the Internet for a long time and could not find a solution. Finally I found a question that can solve the compatibility problem today, and finally solved the problem:
1, I found that if you use the Microsoft Pinyin input method, it may lead to Disappeared, I don't know what's going on, sometimes it's okay
2, I set the MTU value according to other people's methods, by: start, program, attachment, command prompt (run as administrator) - open DOS In the window bar, enter the command after the cursor:
netsh interface ipv4 show subinterfaces
This command is to check your connection name and MTU value. Under normal circumstances, there will be several lines of data, which is displayed on your computer. For all network connections, the first column is the MTU value and the Windows 7 regular version is 1500.
Determine the connection to be modified, enter the command:
netsh interface ipv4 set subinterface "local connection" mtu=1000 store=persistent
Note: "" is the name of the connection you want to change, Windows7 default It is a local connection.
mtu=1000 is the mtu value you want. The test result is under Windows7 system. If you use router, you can change it to 1000 and below. It is recommended to set it to 1000; because it is too small, it will affect the speed of web browsing.
After setting, enter exit to exit.
Note: No need to restart.
Then log in to the game and wait for 20 seconds.
3. I feel that such compatibility problems are not necessarily caused by a single problem, other problems may also cause, between the system and the program, between the program and the program, there is another problem. Is the most likely, is the security detection of the TP system, it will start in the lower right corner of the game. If this is not compatible with winDOS7, then the impact is very large, so there are high people who use the following method:
press " Win+R "combination key, open the "Run" window, enter "gpedit.msc" (without the quotation marks), open the "Local Group Policy Editor" window,

expand in order: "Computer Configuration - Administrative Template -Windows Components drop-down scroll bar, find "Application Compatibility" left mouse click,

then find "Close Application Compatibility Engine" in the right window and double click to bring the original " Not configured "Change to "Enabled"

Then find the "Close Program Compatibility Assistant" below it. Also change the method to "Enabled" as above, and then exit all windows. No need to reboot. , you can enter the game directly.
I have not tested this method because I was successful in the first step last night. But after half an hour, a hint was made: miniQQDL has stopped running. But it does not affect the game, I don't know what's going on, this file seems to be an upgrade program? The file name means: mini QQDownload tool, huh, personal understanding.
Compatibility problem is also a solution, select properties on the program file - compatibility program - select "win xp compatible"

Summary: These programs do not need to restart, debug according to the actual situation , remember your own modifications, in case of invalid, then change back, I am not upgraded from XP to Win7
, is directly iso installed, so DNF does not join the registry, I think if reloading the game If you can solve it, you can try it.
Experience is precious, I hope to have a good solution to share it.
