It occurs to you... System failure
It occurs to you... System failure
I've made several mistakes when handling changes to the registry. I assumed the software I use was secure enough, but it turned out otherwise. This experience lasted about four hours. I was preparing for testing temperatures using a case mod (window). For that, I just needed to identify which stress tests were installed and which ones could strain both CPU and GPU simultaneously. During this process, I decided to remove some programs. I mostly rely on IObit's Uninstaller because it performs better than the built-in Windows tool. It offers a feature to delete residual files and folders—very useful if you want to remove any suspicious software without leaving traces. However... it also cleans the registry. I haven't encountered any issues before, but this time felt different. I removed software that was no longer needed. After uninstalling, I ran a scan. Then I opened HWinfo to verify if benchmarking tools were included. At that stage, explorer.exe crashed. Nothing unusual at first, but soon I couldn't access the desktop. Assuming it wasn't critical, I restarted the system. This is when things went wrong. I failed to log in and received the error: "The Group Policy Client service failed the logon." It was my first time seeing this message. I tried rebooting, then opened the laptop and looked for fixes. The first suggestion was to repair the registry, but that didn't help. Other options included creating a new account and transferring settings from the old one. Since I have multiple accounts, I wasn't keen on that. I tried various workarounds—startup fixes, system restore, etc.—but none worked. Eventually, I decided to try a fresh account. Following instructions, I copied all files to a temporary account using a placeholder. The new account still had the same error. This indicated a corrupted setting file or value. Another suggestion was to log in in Safe Mode with the original account. The only real solution seemed to be creating a brand-new account and setting up junctions again. This approach had its issues: sometimes the account would become temporary unexpectedly, and I had to enter Safe Mode just to move files. But everything eventually functioned properly. No data was lost. What I learned? Treat the registry carefully—unless you're starting from scratch.
