Big brother and sister must help

It may be that you set the wrong permissions when setting them, and reset the full control permissions of the administrator in the D disk security, and put them in the security->advanced-> permissions"Overrides the permission items for all child objects with the items displayed here that can be applied to the sub-objects"Hit the hook and press OK. If you can't change the permissions, you can go to the D drive security->advanced-> owner tab to see if the owner is an administrator, if not, change it back to administrator.

re downstairs: silly, everyone is just the default setting for every user. If a specific setting is set for a specific user, everyone will not work for that account.

A low-level mistake was made, and one that is often made when modifying security settings. Note that everyone is a special user group, and like its name, it includes "everyone", including administrators. In Win2000 XP, not only the user, but also the system itself has to use a name called "system" to perform certain tasks.

However, the system does not directly grant NTFS permissions such as the root directory to the administrator or "system", but uses "everyone" to indirectly grant permissions. Just re-add the everyone group, and grant the "Full Control" permission, and the issue should be resolved.

re:re downstairs: Probably I got it wrong, see the smile I remember that in 2004 there was an issue of Popular Software that said, maybe I remembered it wrong.

If you guess the x right, you have to go.

10x-（20-x)*5 =140

The solution is 10x-100+5x=140

15x=240

x=16A: She guessed 16 correctly.

Set Xiaojing to answer x questions correctly and answer (20-x) questions incorrectly;

10x-5(20-x)=140；

The solution is x=16;

Xiaojing answered 16 questions correctly.

Question 1 [(x+2)-5] =0 (x-3) =0 x-3=0 x=3

Question 2: x -1+2x+6-8=0 x +2x-3=0 x +2x+1=4 (x+1) =4 x1+1=2 x2+1=-2 x1=1 x2=-3

Question 3 4x -10x+25-(x +8x+16)=0 3x -18x+9=0 x -6x+3=0 x -6x+9=-12 (x-3) =-12 No solution.

I'll do it, and I'll do it right away if you adopt it, and give you a detailed process.
