Microsoft says that if your systems are not updated, the vulnerability could effortlessly exploit your system by installing new programs, view and delete data, and even create new accounts, all with full administrative rights. In other words, you’d be letting the threat actors go to town on your PC.

— zhiniang peng (@edwardzpeng) June 29, 2021 Do note that this security vulnerability is dangerous across all Windows versions; Windows 10 may clearly be a target, but so are PCs running on older versions of the OS, including Windows 7. Even more so, since Microsoft officially ended support for the OS last year. As for the versions of Windows Server, the company says that it will have updates ready for them soon. (Source: CNN)
