|Kind of depends on how you installed or got the programs to begin with. |
Most of the time you can't improve speed that much with removing applications. You could try msconfig (might be msconfig32) to selectively choose apps at boot. Might start there for ideas.
I would consider making a backup with system state of the whole thing to a remote media. Then restore the system to OEM state.Then apply firewall and perform updates. Then you can use add and remove programs to try to reduce installed programs if they were pre-loaded.
This may not work well if you have downloaded programs that you paid for. They can still be recovered from the backup but may be very time consuming or in some cases impossible to recover.
If you don't have working media the programs are difficult to restore too.
