The Microsoft built Windows 7 in such a manner to deliver speed along
with performance, but with the time your PC/Laptop gets slower and slower. Well
we all face this kind of problem but it’s not the problem of operating system
and mostly every O.S has same problem.
The problem start arising when we install a lot of junk software’s,
here are we tips and tricks to help you boost your Operating System
performance.
Clean Up the Hard Drive
This should be done regularly once in a week, delete all
the unwanted files, like downloaded files, temp files, recycle bin, use Disk
Cleaner.
1. Go
to Start Button, and type Disk Cleanup, hit Enter to start the Disk Cleanup
2. Disk
Cleanup will calculate free space when loaded; Select the files you want to
delete by tick mark.
3. To
delete “Shadow Copy” and “System Restore” files, select Clean up system files
>> More Options tab.
4. Click
OK and Click Yes to confirm.
Perform Disk Defragmentation
This option could be very handy when you run out of
space, whenever we install any software the operating system splits file in the
different part on the hard drive. With defragmentation we can store all the
files in contiguous memory location. For defragmentation do following:
1. Go
to Start button and type Disk Defragmenter.
2. In
the Disk Defragmenter window, select the drive you want to defragment and press
analyze.
Disabling Unwanted Start-Up Programs to Speed Up System Start-Up
Whenever we install new software, few software set their
preference to start during the System start up. As sometimes you don’t use such
software frequently so better to disable them during the start up.
