A patch is an immediate response  to a situation.  if a software company identifies a specific issue with their product and the situation is pausing a threat to the operation of the product , they will appoint a team of experts who will work on the situation to find out a solution. It is called a Patch or Hot fix.  It is not a planned situation and address that  specific problem only .

A  service Pack is a planned collection of patches and fixes that is targeting  a  large group of customers than just addressing a specific situation .

When we press the refresh button or press F5 when you are on desktop , the video memeory of your system is reloaded with the up to date information . If will be fine if you are browsing through network folder and it will help to detect a newly added share , or it will also help to redraw an icon that is showing up properly
But associating  it will any kind of performance increment is rubbish. technically , if you press refresh , the system is taking few micro seconds out of its life to serve your idiotic request and if you right click and refresh continuously , the system will slow down a bit because of the extra hard disk read write cycles it has to perform.

It is always better that you plan the installation before hand and avoid such a situation . But if you are trapped in such a situation , read on and do as i mentioned and things are going to be fine.


I assuming you installed windows XP after windows  7 and now only XP boots up. After you reach the desktop of XP , insert the windows 7 DVD to the optical drive.
Go to command prompt by typing CMD at the run option and go to the drive letter of your optical drive. assuming it as E:  
now move to the folder named boot by typing cd boot  , and type the following command
    bootsect.exe /nt60 all

Now the boot sector for windows 7 is fixed . Reboot and you can see that machine will boot to windows 7. Now our aim is to create a multi boot environment where windows 7 and windows XP can co exist.
To achieve it  you have to edit the boot sector with BCDEdit option  . There are so many thirdparty software available to do this task  but you follow the official way from Microsoft.
I assume you  now booted up your windows 7 and it is working fine. Now  start your command prompt with administrative privileges  . For that  go to

All programs –> Accessories –> right click on command prompt and select run as Administrator 

Hope you find it useful ..
