Want to compile a batch processing, at a certain time in xp, unable to enter the system?
Then, put it in the group policy, windows settings, scripts, startup inside?
I don't know, can anyone help compile it.?

Think more optimistically:
Maybe trying to restrict children who are studying!

@echo off

setlocal enabledelayedexpansion

for /f "tokens=1,2 delims=:" %%i in ('time /t') do (

    set hour=x%%i& set minute=x%%j

    set hour=!hour:~-2!& set minute=!minute:~-2!

    set now=!hour!!minute!

    if !now! gtr 800 if !now! lss 1030 shutdown -s

)

If you want to be unable to enter the system at a certain point in time (such as 12:30), you can use "at 12:30 shutdown -s"; but it feels meaningless like this;

If you want to be unable to enter the system during a certain time period (such as between 8:00 and 10:30), you can put the following script into the startup to start with the computer

@echo off

setlocal enabledelayedexpansion

for /f "tokens=1,2 delims=:" %%i in ('time /t') do (

    set hour=x%%i& set minute=x%%j

    set hour=!hour:~-2!& set minute=!minute:~-2!

    set now=!hour!!minute!

    if !now! gtr 800 if !now! lss 1030 shutdown -s

)

Later, when testing, a small problem was found, that is, the & after set should be closely followed by the previous sentence, and no space should be left, otherwise, it will cause judgment errors.

Such a good command can be found, electronixtar is really powerful. Hey, I just can't settle down to read ntcmds.chm carefully, so I can only always struggle with those old - fashioned commands there - I really should read htcmds.chm carefully.

After a rough look at the help, I found that the net user command can only limit the whole - hour time, and it can't set times like 12:30, 13:15, which is a pity.

Is this batch file placed in Start, Programs, Startup? If so, then the restricted user has already logged in

After executing the command `net user johnsw /time:M-F,8am-5pm`, does it need to rewrite the registry of the johnsw user?
Is the way to解除 it like this:
`net user johnsw /time:all`, or `net user johnsw /time |all`
I think the format I mentioned above is definitely not correct, right?

Speechless～

I'm sorry, I'm a newbie.
Does the net command should revert related registry?

net user /time directly associates with the account, takes effect immediately, heh, no need to set up auto-start items~~ The settings are saved as part of the user profile

Ah, I understand. The friend upstairs is really very clever! I admire it.
