Right click my computer and select properties or select window button + pause button Select performance tab and check system resources if very low will be susceptible to system instability.
To increase resources either use ctrl+alt+del and close any programs not in use.
If you feel brave in the run box type msconfig and enter, select the startup tab. Decide which programs you don't want to run in the background you can uncheck these and restart the computer.
Or if you are feel really really brave. Remember the programs from the startup tab which should be either listed as
a) machine run
b) machine services
This time in the run box type regedit and enter.
In the left hand pane navigate (you being a pilot should be able to do that)
your way to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion \Run
folder in the left hand pane. Open this folder and in the RH pane the programs in a) will be listed. If not you fcuked up. Selecting and deleting each value in the RH pane will remove that program from the startup tab list.
Repeat for the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion \RunServices
folder which will be just below the run folder. This contain the programmes in b)
Doing it this way means that they are removed completely
Hope it help
PS
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Run
folder holds the programs listed in the pre user run section on the startup tab.
