Windows 7 program compatibility assistant is basically useless. Most of the software in China prompts incompatibility, but it is actually compatible. This is just a waste of time.
This section describes four methods to disable the service:

I
: Open Run (hot key: Win + r) and enter gpedit. MSC to open user configuration → manage template → Windows component → application compatibility → close the program compatibility assistant and set it to "enabled"

II
: Computer → manage → service → Disable Program compatibility assistant service

 

3.
: Click Start, enter services. MSC in the search box, and press Enter.






Click "program compatibility assistant service" in the scroll bar and click "stop.

Or execute:

SC stop






Pcssvc

SC config pcssvc start = disabled

To disable the program compatibility assistant warning, use the test computer to determine whether to create a registry key. You can use these registry items to disable the program compatibility assistant to warn other computers. To do this, follow these steps:

1. Run the affected program on the test computer.
2. When receiving the program compatibility assistant warning message, click to selectThis message is not displayed again
   Check box.

   Note:
   This operation creates a registry key in the following registry subkeys:

   HKEY_CURRENT_USER/software/Microsoft/Windows NT/CurrentVersion/appcompatflags

   The item name represents the guid in the appcompat database of the program item. The entry type is DWORD, and the value of this entry is 0x77.

   Note:
   The program compatibility assistant only prompts a warning when running programs that are not blocked.

3. Exit the program.
4. Note the registry key created in step 3.
5. The installation script contains the steps to add the registry key before the installation starts.

 

Again, we do not recommend disabling PCA for home users because this will cause system instability. Then, as a senior user and administrator, disabling PCA can save time and avoid annoyance.
