In WindowsXP Professional (for personal use) I had uninstalled a faulty programme to reinstall it and saw an executable file in the start menu in the top box. It was just called "Setup.exe" and I looked at properties and it said "unknown" so I thought it was something the uninstalled programme had left. I changed it to open with notepad so it couldn't run anything iffy and removed it from the list. I found I had accidentally changed every single programme icon to open with notepad and nothing will run! I found the file I have changed and it's in the Windows/prefetch folder but now I don't know what to substitute for notepad so that all my other programs will launch again. Can you help please? I'm sorry for the noobiness, I don't use windows often nowadays

I'm going to caution you against doing something and then turn around and ask you to do it.

While I don't recommend running commands that you might get from some random website, I've attached a file that will restore your .exe file behavior. Since it is shown below, you can see nothing malicious there.

Copy the lines below and save them to your desktop in a file you name FixEXE.reg. Now double-click FixEXE.reg, or right-click and select Merge. This makes a change to your registry that should solve your problem.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.exe]
@="exefile"

[HKEY_CLASSES_ROOT\exefile\shell\open\command]
@="\"%1\" %*"

I hope this helps,

I suspect the .lnk association not the .exe
I get this problem at least one a mount.

Copy the following code to a text file then rename the file from .txt to fix.reg (.reg is the most important)
Run the registry file, Import and restart...

Here is the code:
