Hi diverdeb,
How many is a bunch? And what else were/are you running? Search on your computer and check the location of rundll32.exe. It should be in the c:\Windows\system32 folder. Anywhere else and it's likely malware. It is used to load various ".dll" files requested by Windows.

It is quite normal to see several rundll32.exe instances in "prefetch" (each with a different set of numbers after their names). I have 11 in my XP prefetch folder right now and the computer runs just fine.

They simply retain information to speed up rundll32.exe operations and do not "run" in the true sense of the word. Prefetch files are NOT the cause of your slow running.

You need to explain more about the problem you are having so that we can help, avoiding any preconcieved ideas. There are many reasons, such as viruses and/or too many background programs running. It wouldn't hurt to install and run MalwareBytes freebie because this often finds and fixes viruses etc that AV's miss.

You might get a small improvement if you install and run CCleaner freebie and defragment the HD too but I suspect there are other reasons for your issue.

What did you mean by "Only old posts available"?

Always pop back and let us know the outcome - thanks

yes, everything you said is right on point. Ran McAffee scan because I saw it is only scheduled to run every three weeks. Net book is better now. Defragging now, thanks for reminder. It is a low power HP net book. I do not like it. I meant the old posts I found to answer my questions were from 2005

Yep, netbooks do not usually have very fast processors, so even adding more RAM doesn't always make a lot of difference. Thx for clarifying bit about old posts.

If you decide against using CCleaner then clear your temporary internet files in your browser(s). In IE you can set the space used for them and 50MB should be plenty.

Hope you manage to improve things further.
