Ainhi

If you notice that your PC isn't responding as quickly and effectively as before, this application can serve you well.

Ainhi is a simple utility that lets you optimize the performance of Windows XP by modifying the Windows registry.

The procedures in the program are very basic, as it handles and automatically changes all entries that have been modified and altered in order to return the operating system to its initial state.

In addition, all these changes can be easily removed for the sole purpose to restore the system to its original state before using Ainhi, if you do not see another solution.

In any case, care must be taken when modifying the Windows registry as there are some complex options with which if you don't have too much knowledge, they could be detrimental to the performance of your PC.
