Once in a while your computer may be clogged down by problems in the registry.
However there is no need to call the hardware engineer unless you have tried to sort the problems in your computer from your end.
You can simply download or buy a good registry cleaner and run a thorough scan of your computer's registry.
The cleaner will scan the registry thoroughly and find out the invalid entries in the registry.
It will then ask you whether you want to remove invalid entries and you can simply click on yes.
You can then simply restart the computer and see that the performance of your computer has improved considerably.
However it becomes very important to backup your registry before you use registry software.
This is because you may very rarely observe that the program may have removed some entries that were important.
In fact some programs may not work after the registry software has done its job.
Though this is a very rare case we can't take any chances.
Hence you should always choose a registry cleaner which has a registry backup option.
When you click on the registry backup option the cleaner first back ups the whole registry and only afterwards it proceeds with the process of checking the registry for errors.
Once it finds the errors it will ask you for the cleanup process.
Once it removes the invalid entries you will see a considerable improvement in the performance of your computer.
However if you find out that there are some problems caused after the cleanup, you can simply rollback the action since you had already taken a backup of your previous registry settings.
Hence we see how important the registry backup function is.
Using the backup function you can simply restore the registry to its original state or you can simply rollback those actions that have caused a particular problem.
Some registry programs also help you backup your registry to external media such as CD and pen drives so that even if your registry crashes after the test you can simply restore it to your current state.
It might sound very complicated and most likely be dangerous to use registry cleaner software, in fact using this software is the best solution to maintain your registry, backup your registry, and speed up your computer.
Due to the excess of registry cleaner software offered on the net.
You will rarely find the one that allows you to backup your registry either manually or automatically.
