Locking a folder or file in Windows isn’t a tricky thing to do. Windows itself gives you all the necessary options. So let’s go ahead and learn about it.Why you may need to Lock a File or Folder?
There are many reasons why you may feel a need to lock a file or folder. The most common reason is that you share your computer with others. Alternatively, you want to safeguard your files or folders and prevent them from being accidentally deleted. Or if you believe your PC is at risk of getting hacked, someone might steal sensitive information from you.
Locking a file or folder can help you control access to the data and ensure that it is not modified or deleted accidentally or intentionally. It is also helpful in cases where you need to ensure data integrity is maintained.
Windows comes with a built-in option to lock a file or folder. The feature is known as File encryption. Encrypting a file or folder with Windows ties the encryption to your account. This means that when you are logged in, the operating system automatically decrypts the files for you. However, if someone logs in using a different account, they will not be able to access files that were encrypted using your account.How to Lock a File or Folder in Windows 11/10?

In Windows 11, things have changed. As you can see in the above image, while it is tied to the user account, there is no option for a recovery certificate. The certificate is not generated at all.

It doesn’t perform one test and gives a result. Instead, it checks using multiple programs, and if there is a problem, you will know about it.

It’s only testing the memory, and it should be fine even if you have exited in between. However, you will have to force shutdown the PC to exit the tool. I would still suggest that you better wait it out. Keep the PC plugged, and get something else done in the meantime.Can RAM suddenly go bad?
Any hardware can go bad with time or if there is a manufacturing fault. The same applies to RAM. If everything looks good, the memory test can reveal if there is an issue with the RAM. If there is a fault, it would be best to replace it with a new RAM.
