A list of infromation and data ---called the PCs registry--- is consequentially created with an operating sytem loaded into the machine. The registry acts like a directory of sorts to record all the relevant and often the irrelevaninformation for easier admission by the operrating system. Without a registry and the informatioon are sprinkled at random in the system, the workstation will take without end to go over, select, retrieve and use the necessary information.
Complexity comes later
Using the computer allows the intermittennt enry of upddates to file systems, setitngs and other software requrements from time to time, further complicating the operating course of action. Imagine a tree of interconnecting banches, different stems fsuing into others, many not ending in leaves but into other stems, aftrer that you can have an idea of how complex such a registry can be. And if you know what a garden maze looks like
Moreover, although new updates are laded into the system, the old fiels they rpelaced or superseded are not deletted nor filed in otheer plaaces. They stay where they are, and althugh not used, are still accessed by the computerrs operating system each time you boot the device to use it. The system rads the file, decides if it is relevant or not, copeis it into the memroy if related or drops it if not, and goes to the next file.
If you open an automatic update infdormation as prompted by the system, you will see that there are many updates that are clearly superseded or rplaceable by later udpates. Yet they still will be loaded into your ssytem if you are not caareful and be selectiive in what you doownload. All the updates between your last and the pesent updating in reality will be loaded with the automatic upate process. As long as it is not there, it will be oladed.
What happens after
Finally a registry loaded with not needed information is made that the systm yet reads each time. All thee retard the workstations operatiion and may even make it crsah later if left uncorrecrted for some time. A collapse totallly halts the operation and may, at the same time, damage the system itself by corrupting bits of information. Too much conflict among the instructions and something is bound to give up somewhere sometime.
A registry cleaner scans the registry from start to end, eliminating the redundant and unrelated entries, then closes up the gaps created. Thus the regidstry becoimes leaner and the files are more easily accessed, resulting in a faster and more accurate opleration. Not only do you require a regoistry cleaner, but you should use it frequently, maybe even once a week.
