- After updating, you may get errors that some applications and software no longer work or work incorrectly.
- It consumes huge amount of CPU and Ram while updating, secretly. So when I type a document, browse the internet and/or watch a video, it freezes.
- If you use some cracked software, the update would remove it and make it a trial ( that is for MS products only I guess).
At least those are my experiences, and I choose to disable its automatic update and check it once in a while. If I need to update any software, I go to that software directly.
