I would recommend downloading and using cc cleaner. Also deleting and clearing browser history and cache.
Also make sure you use a good brwoser such as maxthon cloud 5 and that no extra tabs are up with wgt playing client. Delete all the extra tabs after having the playing window open.
I use maxathon 5 cloud browers, no extra tabs open
144 hz monitor with freesync
logitech g303 500 ms polling rate mouse
high rated 50 mbps connection
I use cc cleaner twice a week. I clear cache every day except for wgt which I do only once a week
lastly make sure you turn off all anti virus software while playing, this includes windows defender that windows 10 automatically has turned on.
I have virtually no meter problems at all using windows 10
