windows explorer

This is caused by a damaged .cpl file. These files populate Control Panel with tools (for Windows 95 and Windows 98 are located in the %SystemRoot\System folder).
Then the solution for win 95/98 is :
1 Create a new folder on your desktop called "temp" (without quotation marks). To do this, right click and empty area on your desktop, point to New , click Folder , and then type temp .

2 Move all of the .cpl files out of the System32 folder and into the Temp folder that you created.

3 Verify that Control Panel opens. Note that Control Panel does not contain icons after you move all of the .cpl files out of the System32 folder.

4 Move the .cpl files back into the System32 folder, one at a time, and then open Control Panel after you move each file to verify that Control Panel opens.

5 If you move a .cpl file back into the System32 folder, and Control Panel does not open, delete the file, or replace the file with a known, good .cpl file.

For the .cpl files :

In Windows 98, all of the base Control Panel .cpl files are on your Windows 98 CD-ROM and are located in the compressed Win98_28.cab file.

In Windows 95, all of the base Control Panel .cpl files are on your Windows 95 CD-ROM and are located in the compressed Win95_11.cab file. However, the Inetcpl.cpl file is in the compressed Win95_09.cab file, and the Jetadmin.cpl file is in the compressed Win95_16.cab file.
