Clean It Time

Should i press repair becuase 1 mistake apperntly can cause big problems..

Yes, it will immediately ask you if you want to back up the changes, click yes and it will save a reg file for you to merge back into place if something goes wrong.
oops! I’m mistaken, that’s CCleaner! Sorry! Glary Utilities has a Restore folder in the drop down menu to the right for undoing changes. Hope this helps! 🙂

I am wondering whether I have to get a license or something to run the home business (1person).
Also, is it ok to create company logo and name without registering to the state?
If I have to, what are the steps for it?

You need a business license which is cheap and you get it from your city, should be at your city hall.

Next since you are not selling a product you don’t need a resale permit but if you decide to sell a product you need one which means you would need to collect and pay sales TAX.

If you use your name as a business name you don’t need to file for it (I.E. John Smith Enterprises) but if you want a separate business name you need to file for a fictitious business name (small fee and filling out some forms from a courthouse). If you don’t file for the name then down the line anyone can file the same name and force you to stop using it (he who files first has legal rights to it).

As for a logo, that’s 100% up to you. You don’t have to register the design but if you think you might end up very big then you could file for a trademark (less than 15% of businesses file).

It’s a good idea to get insurance but it’s not mandated.

rather than by individually by saving each of the keys?

Many keys are interconnected. Think of the registry of your PC as the brain connections of the computer. As a result if you only backup a given number of registry keys and not all of them, it might happen that you are lacking a certain amount of additional unbacked-up keys dependable on or related to the ones you backed up. End result: partial backup is useless or has a great chance to be so.
