I'm trying to avoid a repeat issue if it occurs in the future. Earlier this week I noticed ancient threat history item in Windows Defender. Since Microsoft prevents you from simply deleting the Service folder and clearing it now, I tried deleting the Event Viewer Log (another online recommendation)...that didn't work. I read and followed the online recommendations to boot into Safe Mode and then delete the Service folder. I did that, logged back into Windows, and it had worked, or so I thought. I immediately noticed that several Windows functions (logging in, opening File Explorer, Opening Windows Tools, etc.) became extremely slow. I found that they were tied to Windows Defender Realtime Protection. If I turned it off, everything was fine.
I tried repairing Windows Defender from within "Apps." When that didn't work I even tried "Reset" from within Apps. That didn't work either. I did a System Restore to before I removed the files but that failed to fix the issue too. Ultimately, I ended up doing a "Repair by Reinstall" and it has worked. However, I just used Powershell to see what the purge frequency is for Windows Defender Protection History. It came back with "0" meaning it never purges. I thought I read somewhere that it is supposed to be 15 days. Can someone please confirm what the purge history time is for 23H2? Also, should I need to purge it again, and not corrupt (or whatever happened) it again, is there another safer way to purge the protection history? Admittedly, this was right after Tuesday's Windows Update so it is very possible that did it too.
