last successful boot

hoo boy. win9x doesn't have the feature of 'press the spacebar to return to last successful boot' like NT/2000. you need to backup your current registry, then go looking for an older version to restore. The registry is contained in two, hidden, read-only, system files in the windows folder. boot with the f8 key to get the boot menu, select Safe Mode Command Prompt Only. type this:
attrib -r -h -s \windows\system.dat <enter>
attrib -r -h -s \windows\user.dat <enter>

copy those two files into a backup folder.
now look for older versions:
type dir system.* /s (same for user.*)
when windows installs it creates a backup of those two, system.d01 (likewise for user) or something or other. depending on what's wrong, you may be able to replace just system.dat.
also other programs create backups of the registry when they install (such as Norton). copy (important verb) what you find into system.dat (user.dat) and try. you are going to need to reinstall whatever drivers/applications thatwere installed after the date on the replacement .dat files...so use the most recent one you can...
tell us why you need to do this and maybe we can help you fix with needle-nose instead of sledge-hammer (smile). good luck.

Please refer to MS Knowledge Base Q131431.
http://support.microsoft.com/default.aspx?scid=kb;EN-US;131431 (Remove any spaces).

This article explains how to restore the registry to its state when you last successfully started Windows 95.
Basically, you boot the Windows 95 to the ?Safe mode with Command Prompt only?, rename the file ?System.dat?, and reboot.

If this does not resolve your problem, the article suggests renaming the file ?System.1st? to ?System.dat? to restore the registry to its state when you first started Windows 95 successfully.

If this does not resolve your problem, the next step is to reinstall Windows 95.

For step-by-step, please read the sections ?Using System.da0?, ?Using System.1st?, and ?Reinstalling Windows 95?.

It would help to know what the actual problem is.

The registry file is actually named "system.dat" this file is located in the C:\windows folder. As mentioned it is hidden, read only and a system file. The three attributes mean that the file cannot be changed unless the attributes are removed.

Obviously since it's hidden you won't be able to see the file unless you use the "/a" switch in the directory command "dir".

To be able to view the file in DOS you need to go into the windows folder and use the dir command followed bt the /a switch,

cd windows

dir system.dat /a

You can also run registry repair, backup and restore features from DOS. Boot to a dos prompt and type

scanreg

There will be a choice to backup or restore from previous backups of the registry there's up to four available. If you try one of the backups and it doesn't work you can run scanreg again to change back. Be careful of the date if it's too far back the registry may not match your current install. The same goes for restoring system.da0 & system.1st.

You can also try "scanreg /fix" which will attempt to repair the registry.

A suggestion if you do decide to go with system.da0 check that the size is pretty much the same. If it's a lot smaller then I wouldn't use it.

System.1st is saved durring the initial win95 setup and depending on changes made to the system may be worse. If you use system.1st you'll need to reinstall software and drivers or any devices that have been added since the initial installation.
