Difference from standard Windows XP computer lockfeature
A lot of users believe that Lock My PC (as well as any other third party computer lock software) is useless because Windows XP has integrated computer lockfeature. Well, indeed, you can simply press Win+L onWindows XP computer keyboard and your screen will be safely locked. What advantages Lock My PC has over Windows computer lock?

First of all, when your computer is locked by Windows Lock feature, anyone who has Windows Administrative privileges can unlock your computer. Such unlock will force to close your session (all unsaved changes will be lost). If Welcome screen option is enabled on your computer (the default settings for non-domain computer), Win+L doesn't lock the computer at all - it temporary switches the user off and displays the welcome screen - if you share your computer with others, they can logon with their usernames and use your computer. Moreover, if you share your account with other users (it's common for home PC), Windows XP lock feature is useless at all - your folks will unlock your computer without any problem.

Another benefits of Lock My PC in comare with Windows lock feature:

• Custom lock screens and transparent lock screen options - your computer can be used as a presentation machine - the screen displays pictures or video, but nobody can touch your computer;
• Secure Lock before Windows welcome/logon screen;
• Displaying unsuccesfull unlock attempts - you will be notified if anyone tried to unlock your computer;
• If Lock My PC is used in muilti-user mode, a supervisor can unlock the computer without closing user session;
• You can lock CD/DVD ROM doors along with thedesktop, keyboard and mouse - this can prevent CD media from being stolen while you are out;
• Command line support allows you to use Lock My PCin Internet kiosks.

How to make your own theme?

Theme Name

Decide what you want to call the Theme. Create a folder in C:\Program Files\PLUS!\Themes name it what you want the name of your theme to be. This keeps everything in one place for you to keep everything organized.

Wallpaper

Chose your background picture. Make sure it is in .bmp form. Place your bitmap into your new folder you created. You might want to then change the name to the same name as you named your Theme. For example if your theme is going to be called Mountain then rename this bitmap to say Mountain.bmp. Right click on your desktop, click properties, then click on Background browse to you new folder and choose your wallpaper.

Color Scheme

Right click on your desktop, click on properties, then click on appearances. You can chose the colors and fonts you want that complements the new wallpaper. After you've picked your new colors and fonts then click on the save as and save it with the name of your new theme. Example: Mountain. Click on apply.

Cursors and Icons

I use MicroAngelo 98 and IconEasel 98 to create my cursors (creates animated cursors too) and icons. These are very good products well worth the money. If you would like to try it out there is a demo version to download click on their names above. If your not going to create your own, you can find lots of cursors and icon packages on the internet. These packages are usually free for personal use. If you use cursors or icons from these packages or from another theme make sure they are not copyrighted and rename them with your new theme name and short description. Example: Mountain wait.cur then move it to your new theme folder. This makes it much easier to put all your theme components into your theme, and for the people who download your theme to recognize which files go to which themes.

You can draw it yourself or copy and paste a piece of clipart or photo; and then fix it up with a cursor and icon software product.

Sounds

you can find these wav. files on the internet or create your own. There are products like Gold wave or Cool edit you can use to edit and manipulate wav. files. Then name them after your new theme. Example: Mountain recycle.wav. Move them to your new theme folder. The trick to deciding on your sound is choosing ones to fit each event. Don't make these too long because it gets on peoples nerves and they will download a different theme to replace yours.

Screen Savers

You need a software program to help you with this part. There are so many I couldn't even list them.

Now all you have to do is make it a theme. We are going to apply all your components to your desktop and create the theme file. Right click on your desktop, click on properties and then backgrounds choose your new bmp. file under wallpapers and click on apply (if you haven't already done so.). While your here decide if you would like it to be tiled or centered. Click on the one you decided on.

Now while your still in there go to the appearances tab and choose the scheme you saved earlier, click on apply.

Now go to the Plus! tab still in the properties window. Click on change icon and browse for your new icons that you saved in your new theme folder.

Now click on start, then settings, then control panel and select the mouse. Go to the pointers tab an go down the list and browse for each of your new cursors in your new theme folder. Click save as, naming it after your new theme, and then click on apply.

Now go to the control panel again this time select sounds. Go down the list and browse for each sound in your new theme folder. Click on save as, naming it after your new theme name, then click on apply.

Finally, go to the control panel again and select desktop themes. Click on save as, now naming your theme, then click on apply.

Startup/Shutdown Screens

If you are interested in creating Win 95/98 Startup/Shutdown screens to go with your theme you need to create or edit a picture you have in your graphic editor such as Paint shop or Photoshop and make sure this image is 320x400 pixels and saved as 256 color RGB Encoded Bitmap. Then you can put them in your theme folder and open up a utility like ZD logo animator and resave the startup screen as logo.sys and the wait screen as logow.sys and the safe to shutdown screen as logos.sys, you can also use this utility to animate your logo screens. To implement them into your desktop:

*.sys file type is usually hidden in most people's computers under Win95. You might have trouble in finding *.sys files for copying files. Go to Explorer choose View menu, then select Options... in the dialog, enable "Show all files" or use a DOS window, in which most *.sys files can be viewed normally. I usually just use the find function entering c:*sys (or whatever is your hard drive) This file is usually in c: or in c:\windows Extract the new .SYS file to a temporary directory.

Move (backup) original "start-up" logo, "LOGO.SYS" from the root directory of your boot drive, usually C:\ to another temporary directory. (If you are using a compression utility or cannot locate the logo.sys file, please see the notes below.)

Use DOS window or Explorer to copy new logo file to the root directory, renaming the new copy to "LOGO.SYS" (If you are using a compression utility, please see the notes below.) Example of DOS command: copy c:\temp_dir\xrxlogo.sys c:\logo.sys

Restart your computer and you're done!

* Note *

If you are using a compression utility on your boot drive, you must put logo.sys in the host for that drive. (For example, if drive C: is compressed and its host is the G: drive, then logo.sys should be placed in the root directory of the G: drive.)

The default logo.sys is embedded in io.sys file. If you cannot find logo.sys in your drives, including the host drive (see above), chances are Win95 is using the logo that is embedded in io.sys as your start up logo. In this case, you don't have logo.sys to backup. Simply place the new logo.sys

in the root directory of your boot (host) drive. Logo.sys in the root directory will take precedence of the one embedded in io.sys file. To get back to the original win95 logo, simply rename the logo.sys to other name.

* To restore the original win95 logo, you must save (backup) the

file in step 1. Then just copy the original logo to the

designated directory.

Bypass Windows File Protection in Windows XP

There are two different solutions, depending on whether you have SP2 installed or not.

If you don’t have SP2 installed

Locate the file sfc_os.dll, which should be in your System32 folder. Copy it and name it sfc_os.bak. Open this file using a hex editor such as XVI32,which is an excellent freeware. This is an extremely simple edit and does not require an editor with advanced features. All you need to do is change two values. The location of these values will vary depending on whether you’re using Windows XP without a Service Pack or Windows XP with SP1, but the actual hex values to change will be the same.For Windows XP with no Service Pack installed, go to offset 0000E2B8 (E2B8 hex). For Windows XP with SP1, go to offset 0000E3BB (E3BB hex). At those offsets, change the hex values 8BC6 to 9090.Note: Depending on your hex editor, you may see the value separated by a space, as in “8B C6”. If you can’t find the values, do not proceed. It could be that your version of XP is different. The edit as described here only applies to English retail versions of Windows XP.

If you have SP2 installed

Disabling System File Protection in XP prior to SP2 involved editing the sfc_os.dll file, but the version of sfc_os.dll that comes with SP2 is different, and you cannot disable file protection with it. With SP2, you need to use the previous version of the sfc_os.dll file, which is 5.1.2600.1106 (the one with SP2 is5.1.2600.2180). Open sfc_os.dll with a hex editor and go to offset 0xECE9. The values to change are 33 C0 40. Change these to 90 90 90. Save your changes. Rename the file with a .bak extension (sfc_os.bak). The original exists in two locations: the\Windows\System32 folder, and the\Windows\System32\dllcache folder. Place a copy of sfc_oc.bak in both these folders. Then in the dllcache folder, look for cmd.exe, double-click it, and enter this command: copy SFC_OS.BAK SFC_OS.DLL /Y Next, go to your System32 folder and do the same thing. Look for cmd.exe, double- click it, and enter exactly the samecommand.

Points to remember

* If you have a problem overwriting the files, you can do the copying within the Recovery Console, or you can try Safe Mode.

*The dllcache folder is a hidden folder.

*It is important to copy the file to yourdllcache folder first.

*If you’re prompted to pop in your Windows CD, click Cancel.

Once the files have been copied, shut down your computer and restart it. The final step is to disable System File Protection in the Registry. Go to HKEY_LOCAL_MACHINE\SOFTWARE\

Microsoft\Windows NT\CurrentVersion\Winlogon. In the right-hand pane, if it doesn’t exist, create a new DWORD value named SFCDisable. Double-click it and ente “FFFFFF9D”. Exit the Registry Editor and reboot. You’re done.
