I purchased this HP All-in-One desktop in June 2023, equipped with an 11th Gen Intel Core i3 processor and 8GB of RAM from Z&O Electronics on Amazon. Initially, I was pleased with its performance; however, within a year, I encountered a significant issue.Last week, my computer was suddenly locked by BitLocker encryption, which was activated without my intervention and, unfortunately, without providing any recovery key. This left me unable to access my data, causing considerable inconvenience. I was not aware of BitLocker being part of the Windows package at the time of purchase, and there was no forewarning about this feature or its implications.I believe sellers and Windows must ensure that buyers are informed about such potential locks and the necessary recovery steps or keys at the time of purchase. This experience has been frustrating, and I am currently seeking a resolution to regain access to my files.For potential buyers, I recommend verifying all security features and ensuring you have access to recovery keys for BitLocker before encountering a similar issue. While the machine's specs are decent for the price, the lack of upfront information regarding BitLocker was a significant oversight.
