Windows can also restrict program execution without group policy.

In order to prevent roommates from playing QQ games with my computer
, I use the Group Policy method to limit. However, when you need to run these programs, you have to go to the Group Policy Editor to cancel the restrictions. It is very troublesome to use the recovery limit. Is there a way to restrict others and not limit yourself in Group Policy?

[Solutions]

Restricting specific users from running a program does not require group policies. Access control using Windows
can also be implemented. Let's take the most widely used Windows
7 as an example.

[Solution Method]

To prevent a roommate from running a program, first find the source file of the program. Take Steam.exe as an example (Figure 1). Once you find this program, right-click on it and select “Properties> from the pop-up menu to open the Properties window, then switch to the "Security" tab and click on the "Edit" button (Figure 2). In the dialog box that pops up, click “Add”, enter the username you want to restrict, such as “小王”. Once the input is complete, click “check the name”, then click “OK> to return to the previous window (Figure 3).

Select the newly added “小王”, in the "Reject" column, check “Read & Execute> (Figure 4), confirm Just fine.

If you use the "Small King" account to execute Steam.exe in the future, it will be rejected by the system (Figure 5). Of course, I only provided another idea here, for reference only.
