Windows and Installer Folders Enormous

[telders]

My late husband's old Dell runs Windows XP. It has 37.2 GB. I keep running out of disk space, even though I empty recyle, clear history, cache, temp internet files, and run disk cleanup. I ran ZoomDisk and found Windows takes 19 GB and Installer 14 GB. I have no music, videos or anything else because of lack of space. I'm not a geek, but Googled and learned Microsoft no longer makes available Windows Installer Clean Up. How can I safely regain space?

Delete patch uninstalls from the windows directory, they show up as $NTUNINSTALL<number>$ and $hf_mig$, setup your browsers' directory for temp files to one folder. Make your windows temp folder on the root directory like say "C:\Temp". Add those folders to an app. like CCLEANER. You will need to clean "C:\Windows\Temp" and "C:\Documents and Settings\<user name>\Local Settings(Application Data)\Temp(Temp Internet, History)" go through all users.
Make sure to set browser cache limit, usually 1% of memory.
If you have a setup directory, you can safely delete that given you have an installation CD.
You don't need ZoomDisk, you can just open Windows Explorer, right click folders and click properties, it'll give you the size of the folder, find the fatest ones and mark them down, if it is in "C:\Windows\" go through subfolders one by one.
Other than that I'd have to physically look at it myself.
