hi friends yo may have come across many articles that windows 7 has many hidden themes but where are they located. These themes too are high definition themes. And will surely make feel your desktop come live. To search for these beautiful high definition themes go to :

(Note this folder may be hidden in your windows so better is to paste this address in your address bar )

1. Drive Defragmenter : This tool is a very much essential  tool for a PC user as it rearranges the fragmented files in an order thus making the computer faster.

1. check your disks for bad sectors containing errors & corruptions. To do this go to My Computer => right click on the drive you want to check => properties => tools => click on Check Now => tick on both options & click start. The disk will be checked for bad sectors & corruptions.
2.  to defragment your disks. Many file in windows are fragmented. This happens due to deletion of data from the sector windows has kept it. This basically happens in the Windows directory ( c: ) because Windows writes & deletes data for it use thus leaving lots of fragmented files in computer. So to defragment your disk go to My Computer => right click on the drive you want to check => properties => tools => click Defragment Now => select the drive you want to defragment & click on defragment =>then the process of defragment willl start and thus your computer will be defragmented.
3. disable some of the services like Indexing Service. The indexing service helps  to search file faster by making the content indexed. But it reduces the speed of the computer. To disable this service visit    My Computer => right click on the drive you want to check => properties => uncheck the " allow file on this drive to be indexed in addition to file properties => OK . this will disable the indexing service.    (Note: do not turn of computer during this process.) 
4. kill some of the process that are not used by you using task manager. 
5. download and install TUNEUP Utilities. It is a very good tool to optimize the speed of the computer.
   

1. Start your computer.
2. After all the process & services have been loaded, in the "USER LOGIN" press CTRL+ALT+DEL.
3. There a window pops out asking the username & password.
4. In the user name type "Administrator" & in the password type nothing.
5. press enter or ok.
6. Windows xp will start the hidden administrator account with administrative rights.

(NOTE:- Don't use it for hacking into someones computer illegally. It is only for you if you are in trouble.)

Generally some people don't like to use internet explorer for surfing web. This may be due to the appearance or something else. But internet explorer is a very good web-browser which is much faster & safer.
But the point is that if users do not use internet explorer then why not to remove it from the computer.
It saves space.

So let us uninstall internet explorer. To do this in Windows 7:-

1. Go to start.
2. In the search box type " Turn Windows Features ON or OFF".
3. Then click on the " Turn Windows Features ON or OFF"." botton.
4. A dialog box will open.
5. Search for Internet Explorer 8.
6. Remove the check mark & press ok.
7. Then windows will start uninstalling Internet Explorer 8.

(Note: This feature can also be used to remove & install many other windows features.)

hi friends i thought of writing in the context of " how to run Windows XP programs & softwares in Windows 7" because I found many of my friends asking about the troubleshooting problems while installing softwares & drivers in Windows 7 . We know that windows7 is the latest OS by Microsoft. So the softwares & drivers created before the publication of Windows 7 might not have known codes or formats for windows 7. So during installation they show errors like " OS not found" or "Un-supported OS version? ". To fix these kinds of problems Windows 7 has a very good function called "Troubleshoot compatibility" in the right click menu.

Now let me show ho to do this to run all the softwares and drivers in Windows 7 by using "Troubleshoot compatibility":-

1. Select  the setup file ( .exe file) and right click on it.
2. Then  select on the "Try Recommended Settings".                                                  
   
3. Then click on "Start Program"  
4. Then the program will start & you can install it in Windows 7.                            

(Note:- This may cause some instability  in some programs. so, it is better advised to have the latest driver & softwares.  )           .
