How do I prevent two users in XP from accessing each other s files?

When the file system format is NTFS, take advantage of the security of NTFS Right-click on the folder properties --> Advanced --> check Encrypt content, use this carefully, other users do not have access to it, which user encrypts, which user can access, if the encrypted user is deleted, there is no creation of the same username in the future.

Use NTFS file system encryption with caution).

The FAT file system doesn't have this.

If you have an administrator account, you can make my documents private, or you can only use encryption software, Optimizer.

Set all the files to your own provided that your hard drive is in NTFS format.

Set a password for your files.

But I recommend creating a new folder that no one else can see or open.

Click Start-Run, type cmd, click enter, for example, if you want to create a new folder called 123 on drive D, you will type it there"d:"Then press enter, and enter"md 123..\"Then press enter to write down the name"123"There should be two of them".

Dot) and then it's OK People enter the d drive and click on 123 This folder will say that the path can't be found Anyway, it can't be opened When you want to open the folder yourself, you repeat the above action just put"md 123..\"Then enter and change"start 123..\"Then press enter and it's OK to delete it"del 123..

Then just get in.

On top of that, you can also encrypt folders or set access permissions.

By default, Windows XP's local security settings require all users accessing the network to be guests. At the same time, in the user rights assignment of Windows XP security policy, guest users are prohibited from accessing the system through the network. As a result of these two conflicting security policies, other users in the network cannot access computers using Windows XP over the network.

Here's how you can solve the problem.

Method 1: Remove the guest restriction.

Click Start Run, enter " in the "Run" dialog box, open Group Policyr, select "Computer Configuration Windows Settings Security Settings Local Policy User Rights Assignment", double-click the "Deny access to this computer from the network" policy, and delete "Guest" inside. This allows other users to use the Guest to access computers using Windows XP over the network.

Method 2: Change the network access mode.

Open Group Policyr, select Computer Configuration Windows Settings Security Settings Local Policy Security Options, double-click the Network Access: Local Sharing and Security Mode policy, and change the default setting of Guest Only - Local User Guest Authentication to Classic: Local Users Authenticate by Themselves.

Now, when another user accesses a computer using Windows XP over the network, they can log in with their "identity" (provided that this is already available in Windows XP and the password is correct).

When this policy changes, so does how files are shared, and by enabling the "classic: local users authenticate themselves" method, we can limit the number of users who can access the shared file at the same time, and set different access rights for different users.

However, we may also encounter another problem, when the user's password is empty, access will still be denied. Originally, there was a "Account: Local accounts with blank passwords are only allowed to log in to the console" policy in the "Security Options" policy is enabled by default, and according to the principle of denial priority in the Windows XP security policy, users with blank passwords will be prohibited from accessing computers using Windows XP through the network.

We can simply deactivate this policy and solve the problem.

Turn on the guest user in the control panel.

Set up shared files so that the two XPs are in the same workgroup. Turn on guest access.
