If you fall under that category then there is no need for you to be worried because you are not even the only one in that kind of situation.
All you have to think of is how to clean your PC's registry.
Your computers registry consist of some basic operating instructions that informs and shows you how the PC operate, they are actually files that are stored in a certain database, so as long as you download, click, watch movies online, install and save or delete files will continue to form and accumulate.
There are times when your operating system would need some information form the registry and then it visits there, there are also times that there would be so many files and so your operating system doesn't know what to do again.
What is left for you to do is to get software that can do the fixing or you will have to do the registry editing all by yourself which could be challenging and complicating.
The two of these methods i mentioned above work effectively depending on how they are approached, take note that if you are not sure with what you are doing you could mess up your registry so badly, but if you make use of a good software then you are on a very safer side what the software does is that it scans your computer and informs you of all the errors on the PC's registry and the computer in all.
If there are any new settings you can always rollback the registry fixing files.
For now the most reliable solution is to make use of the registry cleaner software, I make yes of it on my computer and i have no problems with my computer.
All I do is to run the program weekly and I am not always surprised to find new errors because of the way I use my PC for my works.
I hope you get this as it will do you a lot of good.
Thank you for reading.
