Hi Oytun Bertan ÇAĞLAR.
Thanks for reporting this issue in Microsoft Community.
In your description, you want to delete your Microsoft account.
I noticed that you want to delete your Microsoft account and at the same time you want to delete some other products. I understand your desire to delete your Microsoft account.
However, we are a bit confused about what you have mentioned.
Do you want to delete the information that contains your Microsoft account in Settings as well as Applications, or do you want to completely delete your Microsoft account and never use it again?
Please let me know.
If you simply wish to remove the information about your Microsoft account in Settings as well as Applications, then you can refer to the following steps
1 Right click on the Start button and select Settings
2 Find Accounts, Your info, and here, try switching to a local account
After going back to local account, try to remove all Microsoft accounts in Accounts settings, in Email & accounts.
For other Microsoft apps, please log out of your Microsoft account, and if you wish to completely clean up the information about your Microsoft account, you can try to clear the cache for those apps.
Here are the steps to clear Edge's cache (please be careful to back up important data, such as favorites and collections).
1 Open Edge, click the “...” icon on the top right, and select Settings
2 Click Reset settings on the left, click Restore settings to their default values
3 Click Privacy, search, and services on the left, and find Delete browsing data.
4 Click Choose what to clear on the right side of Clear browsing data now, select everything, and click Clear now.
If you wish to close your Microsoft account and never use it again, then you can refer to the following link to close your Microsoft account completely.
How to close your Microsoft account - Microsoft Support
Note: Closing your Microsoft account means that you will not be able to use it to sign in to any Microsoft products or services, including Outlook.com or Hotmail, OneDrive, Xbox, Skype, Office or Microsoft 365, Rewards, and Microsoft Certification. You will also lose access to any saved BitLocker recovery keys.
When you close your Microsoft account, for whatever reason, Microsoft wants to make sure of two things:
1 It was really you and not someone else trying to close your account.
2 You're not leaving anything important behind that you'll need later.
It's an honor to offer you some advice, and I hope my efforts will make things a little easier for you.
If I have misunderstood, please correct me and continue to contact me and I will continue to help you.
Thank you for your understanding and support.
Best regards,
