When I had Chrome on my WinXP machine, the updates were set for "manual" only, yet auto updates went on regardless. And every time there was
one, my computer slowed to a crawl or froze altogether.
That was why I uninstalled Chrome.
But I didn't have any problem uninstalling it. I just went to Control Panel and used the Add/Remove facility.
Then did a Ccleaner run and then rebooted.
I hope you get sorted soon, Winfrey
