Windows stripped naked by Uninstaller or AV program
I recently experimented with the well-known Advanced Uninstaller Pro and with 360 Total Security. Both the uninstaller and the AV program have cleaning and optimizing functions. After being repeatedly cleaned of all unnecessary or slowing-down data and files, and repeatedly optimized, Windows 7 had a surprize in store for me.
Firstly, I could not connect to my wifi router any longer. Secondly, my whole Windows update history had been wiped away. Windows seemed to be fully updated but a message "Has never been updated" was displayed. Thirdly, I could not restore the system to any earlier date. The necessary data or files had apparently been swept away. I ended up desperately trying to salvage my data in Safe Mode.
Another surprize was that Windows 7 started recovering from its stripped-down, semi-crashed state the next day, so that I eventually postponed my decision to re-install it.
What really happened? Which program (Advanced Uninstaller Pro or 360 Total Security) should I avoid in future? Could anybody shed light on this incident?
