When having problems with your Control Panel, ie; Lockups, System hangs
on exit, ect:
It's a good Idea to Rename all your ".cpl" files. You can do this quickly
from DOS by following the steps below:
C:\>CD WINDOWS\SYSTEM [ENTER]
C:\WINDOWS\SYSTEM>REN *.CPL *.OLD [ENTER]
Then Extract from your Win95 CDROM new uncorrupted ".cpl" files as
shown below
To extract from CD, 1st Change Directories to the X:\WIN95> prompt,
where X is your CD-ROM letter.
Then type the following:
1. Double Click "My Computer".
2. Click View
3. Click Options
4. Click "File Types" Tab
5. Choose New
6. In the "Description Of Type" box enter "Control Panel Extension"
7. In the "Associated Extension" box enter "cpl"
8. Click the "New" button and in the 'Action" box enter "Open with
Control Panel"
9. Enter in the "Application used to Perform Action" box "C:\WINDOWS\rundll32.exe
shell32.dll,Control_RunDLL %1,%*"
Joy.cpl is obvious, it changes the icon. [vjoyd.vxd] is the file that
actually provides the driver for windows.
Joystick driver May be faulty.
Uploaded the latest driver from MicroSoft(www.microsoft.com/hardware),
and that may fix your joystick.
For the joystick, the driver for windows 95 and for DOS comes with
a Diskette or two.
If you don't have one, don't worry since recent games have its own
control for the joysticks.
To check your joystick whether it is working or not, do the following
double click on
My Computer Icon, double click on Control Panel, Double Click Joystick
Control,
in Control Panel and choose your joystick, simple- 2 buttons, 4 buttons,
or 4 buttons with other stuff. and click calibrate, and follow the instructions
as you see on the screen.
Now, that was for games in windows which requires windows data base
for joystick.
In any game, you can find the control options.
If the exact settings you want are not available, choose the closest
match.
If you have "Control Panel>Internet Autodial
1. Click on Start | Settings | Control Panel
2. Click on Internet | Choose the Connection tab
3. Check "Connect to the internet as needed"
Microsoft Windows 95 Microsoft OEM Service Release versions 2, 2.1 This describes how to install and remove codecs and Media Control Interface (MCI) devices in Windows 95. Codecs are used to play compressed files by decompressing them in memory. Adding a specific codec lets you play files compressed in that file format. Removing and reinstalling a codec may solve problems playing a particular file type. MCI devices are drivers that provide Windows 95-based programs device- independent capabilities for controlling multimedia hardware and software. Removing and reinstalling MCI devices may solve problems playing certain files.
Adding All Default Codecs
To add all the default codecs in Windows 95, follow these steps:
1. In Control Panel, double-click Add/Remove Programs.
2. On the Windows Setup tab, click Multimedia, and then click Details.
3. Click the Audio Compression and Video Compression check boxes to
select them, and then click OK.
4. Click OK.
Adding a Specific Codec or MCI Device
To add a specific codec or MCI device, follow these steps:
1. In Control Panel, double-click Add New Hardware.
2. Click Next, click No, and then click Next.
3. In the Hardware Types box, click Sound, Video, And Game Controllers.
4. Click a manufacturer in the Manufacturers box and a model in the
Models box, and then click Next.
The following table lists the codecs included with Windows 95:
Manufacturer_________Model
DSP Group___________TrueSpeech Software Audio Codec
Intel_________________Indeo R3.1 Video Codec
Indeo R3.2 Video Codec
Microsoft Audio codecs_ADPCM Audio Codec
CCITT G.711 A-Law and u-Law Audio Codec
GSM 6.10 Audio Codec
IMA ADPCM Audio Codec
Microsoft Video codecs RLE Video Codec
Video 1 Video Codec
SuperMatch___________Cinepak Video Codec
NOTE: Microsoft PCM Converter is installed by default.
For MCI devices, click Microsoft MCI in the Manufacturers box, click
the model you want in the Models box, and then click Next.
The following MCI devices are included with Windows 95:
CD Audio Device
MIDI Sequencer Device
Motion Video Device
PIONEER LaserDisc Device
VISCA VCR Device
Wave Audio Device
If the codec or MCI device you want to install is not listed, it was not installed by Windows 95. If the codec or MCI device was included with another program, reinstall the program to reinstall the codec or MCI device. If the codec or MCI device is located on a driver disk, click Have Disk and specify the location containing the files. NOTE: Unlike the other MCI devices, the Mixer Device cannot be added manually. This device can be added only during the installation of a Windows 95-compatible sound card driver. When it is installing the driver, if Windows 95 determines that the driver can support the Mixer Device, it installs the Mixer Device along with the sound card driver.
5. Click the Finish button.
Removing the Default Codecs
To remove the default codecs, follow these steps:
1. In Control Panel, double-click Add/Remove Programs.
2. On the Windows Setup tab, click Multimedia, and then click Details.
3. Click the Audio Compression and Video Compression check boxes to
clear them, and then click OK.
4. Click OK.
The default codecs, with the exception of the Microsoft PCM converter,
are removed. You cannot remove the Microsoft PCM converter.
Removing a Specific Codec or MCI Device
To remove a specific codec or MCI device, follow these steps:
1. In Control Panel, double-click Multimedia.
2. Click the Advanced tab.
3. To remove an audio codec, double-click Audio Compression Codecs,
double-click the codec you want to remove, and then click Remove.
4. To remove a video codec, double-click Video Compression Codecs,
double-click the codec you want to remove, and then click Remove.
5. To remove an MCI device, double-click Media Control Devices, double-
click the device you want to remove, and then click Remove.
To fix this it's best to extract from your Windows CD-Rom all the files
mentioned:
Sysdm.cpl
Commctrl.dll
Commdlg.dll
Shell.dll
Lzexpand.dll
Ver.dll
Mmsystem.dll
0= The General Tab
1= The Device Manager Tab
2= The Hardware Profiles Tab
3= The Performance Tab
So just create a new shortcut with a command line of
rundll32 shell32.dll,Control_RunDLL SYSDM.CPL,,2
Try it out, put rundll32 shell32.dll,Control_RunDLL SYSDM.CPL,,# in you Run box and click OK.
Here's another way of Restricting Access to certain system files where little beavers may mess up you system.
Edit the CONTROL.INI file. Add a line to the [don't load] section so
it looks like this:
[don't load]
snd.cpl=no
Replacing snd.cpl with the name of the cpl file you are trying to exclude.
Example; Here's mine:
[don't load]
snd.cpl=no
joystick.cpl=no
midimap.drv=no
sticpl.cpl=no

When you run the CONTROL command you are actually starting Control Panel with Control.exe, not the normal way Windows 95/98 runs Control Panel tools. The actual command line Windows uses is:
"rundll32.exe shell32.dll,Control_RunDLL %1,%*",
Windows substitutes the name of the tool you want to run for %1%. For example:
"rundll32.exe shell32.dll,Control_RunDLL appwiz.cpl"
