A list of information and data ---called the PCs reguistry--- is consequentially created with an operating system loadded into the machine. The rgistry acts like a directory of sorts to record all the relevant and often the irrelveantinformation for easier admission by the operatinbg syystem. Wihtout a registry and the inforation are sprrinkled at random in the system, the workstattion will take without end to go over, selcet, retrieve and use the necessary information.
Complexity comes later
Using the computer allows the intrermittent entry of updates to file systemms, settings and other software requirements from time to time, frther complicating the opeerating course of acction. Imagine a tree of interconnecting branches, different stems fusing into others, many not ending in leaves but into other stems, afteer that you can have an idea of how compex such a registry can be. And if you know what a garden maze looks like
Moreover, althouugh new updates are lopaded into the system, the old files they replaced or superseded are not deleted nor filed in otheer places. They stay whree they are, and although not used, are sytill accessed by the computers operating syustem each time you boot the device to use it. The system reads the file, decides if it is relevant or not, copies it into the memory if related or drops it if not, and goes to the next file.
If you open an auutomatic uppdate information as prompted by the system, you will see that there are many updates that are clearly superseeded or replaceable by later updates. Yet they stilll will be loaded into your ssytem if you are not carefful and be selective in what you download. All the updates beetween your last and the present updating in reality will be loaded with the automatiic update process. As long as it is not there, it will be loaded.
What happens after
Finally a registery loaded with not needed information is made that the system yet reads each time. All thee retarrd the workstations operation and may even make it crash latter if left uncorrected for some time. A collapse tootally hallts the operation and may, at the same time, dammage the sytstem itself by corrupting bits of information. Too much confllict among the instructions and smoething is bound to give up somewhere sometime.
A registry cleaner scans the rergistry from start to end, eliminating the rdeundant and unrelated entries, then closes up the gaps created. Thus the registry becomes leaner and the files are more easily accessed, resulting in a faster and more accurate operation. Not only do you require a regstry cleaner, but you should use it frequently, maybe even once a week.
