Original Title: Windows 8.1 installed well but is unusable....
I've been with Windows since 3.1, installing every new version as soon as it became available.
Today (18 October) I installed 8.1 from the Store. The installation seemed to well but despite restarting several times I get the following major problems:
1/. Extreme system sluggishness with the CPU time maxing out over 'wwahost' (I think) and Windows Explorer amongst others.
2/. Start screen unusable as it maxes out resources and apps take minutes to load.
3/. The new search locks everything up and ultimately fails to run at all.
The installation is Windows 8 Pro 64 bit.
The laptop it's installed on is a Dual Core Intel and is 4 years old. It's fitted with a SSD, it ran 7 & 8.0 very easily. 8 even seemed more sprightly than 7.
I can't install 8.1 on my Desktop or my Surface RT and will wait several months to see if a later iteration works any better.
Has anyone in MS got any ideas about what's going on? I'll try for a couple of hours more but will then have to use a disk image to get back to 8.0.
Thanks and help!!!
