How to find out what program you have uninstalled?

[wmk]

I wanted to uninstal one program but accidentally uninstalled another program.  Is there any way to find out what that other program was?  My OS is vista home basic.

Do a System Restore to the day before the uninstall.

All programs will be restored.

You must then uninstall the program that needs to be uninstalled.

start, All Programs, accessories, sytem tools and click System Restore.

Follow directions.

Good luck

System Restore only deals with Windows system files so unless i'm mistaken the app will not be restored...you may however see it listed in Add/Remove Programs...
Then you can re-install it...

I use XP pro.

System Restore does not uninstall programs but when we restore to a day before the the program was uninstalled,  the program will be there.

Also, any program that was installed after the restore date must be installed again.

The above has always worked for me.

Not just system programs are affected but also regular application programs.

It never hurts to run System Restore. Everything can be reversed to where it was before system restore

Patio is correct.  I actually uninstalled two programs consecutively.  One was Epson printer software, the other one I do not know.  After a system restore to a time before the 2 uninstallations, Epson printer software is not restored.   So I suppose system restore only deals with Windows system files.  And programs installed after the restore point are still there, like Acronis in my case.

Patio, I only have programs and features in Control Panel and within that there's no add/remove programs.  There's only the option to uninstall/change/repair.  What else can be done?

Programs & Features in Vista serves same purpose as Add\Remove in previous Windows versions.
You can try system restore to day before. It won't restore the program, but it'll restore your registry to the day before.
Then, open Registry Editor, navigate to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
and you'll see list of all programs as of yesterday.

There are just too many items in
HKEY_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Uninstall
that I don't know what to make of it.

Is the most recent uninstallation placed on top?   I don't see  Epson printer software.

[wmk]

I have recently done product recovery for my computer.  Is that why there are so many items in the registry under uninstall?

[wmk]

Or is it the several system restores and undo that I did?

[patio]

What exactly is it that you need to re-install ? ?

[wmk]

That is what I want to find out. 
I intended to uninstall "Epson printer software" but accidentally uninstalled another program because I had single-click turned on instead of double-click.
I do not know what program it was that I unintentionally uninstalled.

[Broni]

If it's so important program, how come, you can't see what's missing?

[patio]

I'm guessing it's between D and F....

[wmk]

Broni,  there are too many programs listed in Programs and Features.  Just Epson has 9 items.

Patio,  I think it is anything above E and below B because after selecting Epson printer software by resting on it (single-click being enabled), I moved my pointer upwards to reach the uninstall button.   I must have rested a bit in between to have caused another program being selected instead.

Can anyone tell me the sequence of uninstalled programs listed in
HKEY_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Uninstall?
Are the most recent uninstallation at the top of the page or at the bottom?  There are no dates listed.

That way I can concentrate my search to a particular area.

[Broni]

Are the most recent uninstallation at the top of the page or at the bottom?

Unfortunately not. They're sorted by CLSID numbers.

Broni,
Thank you, eventhough I still can't find the item.
I finally did product recovery for my computer.

Alrighty...
