HPHUPd05 is a Software Update Checker (the 05 is a version number)
HP Component Manager - "Checks the internet for updated drivers/utilities for your HP product"
HPHMON05 - "Monitors the status of the memory card reader slot on a HP printers and displays a tray icon if a memory card isn't inserted. Disable if you don't use the reader "
HP DeskJet Taskbar - "Creates 1 or all 3 icons on taskbar. The 1st one has a yellow border around it warning that ink is low on the printer. The 2nd one is HP Device Detection Software and the 3rd one is about a card being inserted into the Hp printer "
I would UNselect them all (unless you use the last two).
All of these programs can be run via Start > Programs
You have UNselected Taskmon, which is OK, but I would now do the following.
Taskmon monitors programs as they start, and logs that info for Defrag to allow it to try and optimize program startup. It is generally accepted that this does little for performance, and makes defrag run longer.
So, run Explorer, and go to View > Folder Options > View tab and Select "Show all files".
Then, browse to the Windows folder and find a folder called APPLOG.
Select all files in this folder and delete them. (these are the info files)
You have also UNselected Scheduling Agent, which could be OK, but be aware that this is the program that automatically runs "things", such as checking for updated virus defintions periodically. Or running defrag on a scheduled basis. If you depend on these things happening, re-select Scheduling Agent.
(Microsoft Office was OSA. It is a MS program that attempts to start Office Programs faster, and is also the Office ToolBar. So, if you use the Toolbar, you will want to put this one back)
lists most startup programs.
You should now find that your startup is faster, and hopefully your PC is a little more responsive.
