Windows startup programs - Browse database

If you're frustrated with the time it takes your Windows 8/7/Vista/XP PC to boot and then it seems to be running slowly you may have too many programs running at start-up - and you have come to the right place to identify them. This is the original start-up programs (as opposed to processes/tasks) list - one of the most accurate and comprehensive. Services are not included - see below. For further information on this and how to identify and disable start-up programs please visit the Introduction page.

See here for further information on random entries - which are typically added by viruses and other malware or unwanted programs.

Notes & Warnings

If you can help identify new entries and verify/identify those entries with a "?" status (especially hardware specific - such as laptops and motherboards) then please E-mail us (startups_at_pacs-portal_dot_co_dot_uk).

"Status" key:

Variables:

DISCLAIMER: It is assumed that users are familiar with the operating system they are using and comfortable with making the suggested changes. We will not be held responsible if changes you make cause a system failure.

WARNING: This is NOT a list of tasks/processes taken from the Task Manager (CTRL+SHIFT+ESC) "Processes" tab. This displays some startup programs AND other background tasks and "Services". These pages are concerned with startup programs from the common startup locations shown above ONLY. Please do not submit entries collected from this method as they will not be used. For a list of tasks/processes you should try the list at PC Pitstop, the Process Library from Uniblue or one of the many others now available.

Therefore, before ending a task/process via CTRL+SHIFT+ESC just because it has an "X" recommendation, please check whether it's in the registry or common startup locations first. An example would be "svchost.exe" - which doesn't appear in either under normal conditions but does via CTRL+SHIFT+ESC. If in doubt, don't do anything.

To avoid the database becoming too large, all malware entries are only shown using the registry version which is common to all Windows versions. Otherwise there would be multiple entries for popular filenames that viruses often use - such as "svchost.exe" above for example. Multiple malware can also use the same start-up entries, in this case only those with significant differences (such as file location) are repeated in this database.

As more than 25K entries in this database related to malware you should use a quality internet security package. Which ever you choose, keep it updated and get the latest version at least every two years.

There are a number of virus and malware entries listed in this database where specific removal instructions haven't been given. If this is the case then you could try ComboFix, a program written by sUBs that can remove many different types of Trojans and Worms. See here for a tutorial on how to use the program.

NOTE: A number of entries are repeated due to the way that different operating systems display startup items. For example, WinMe lists "POPROXY.EXE" as "Norton eMail Protect" in both MSCONFIG and the registry whereas WinXP lists it as "Poproxy" in MSCONFIG and "Norton eMail Protect" in the registry.

SERVICES: "Services" from the Windows 8/7/Vista/XP/2K/NT operating systems are not included. We fully understand that some programs with these OS's use "Services" as an alternative to load their component parts at startup but these are handled in a different way. We recommend you try BlackViper for information on services for the relevant operating systems.
