PC locks up on starting CC apps

Question

First noticed with Bridge CC now also with Photoshop CC since the more recent updates.
Appears to be scanning my disk.
About 30secs after starting Bridge, disk transfer light comes on continuous and PC then responds very slow.
Lasts about 4 minutes, thereafter PC operates normally.
No messages from Bridge during or after this scan.
Can find find no setting in preferences that controls this.
Purge of cache and camera raw cache have no effect.
Appears to be a Creative Cloud issue as this does not occur with CS6 version of Bridge.
I regard this as an extreemly serious fault as it renders my system unusable.
If no fix is forthcoming I will terminate my CC membership.
PC is running 64bit windows7.
Have just Photoshop and bridge installed via CC.
Lightroom does not show the symtom and was installed before joining CC.
Do not use Behance or store any files on-line.
On further investigation: note in Task manager that little disk activity is occurring.
The IO seems to be logged under I/O Other which suggests app may be performing some kind of system performance test.
Am assuming that Adobe engineers will know immediately from the design what the app is doing.
Note this happens in both Bridge and Photoshop and means both are locked and unusable for some 5 minutes.
As far as I am concerned this makes the apps absolutely useless.

Answer 1

Slowness when opening Bridge is a common issue.  Bridge seems to look for disks and folders and if it can not find it continues to look.  If one has Favorites on your network it can take 5 min. or so to end the search.  It can also cause a 10 second lag when using certain tasks.
A users solution to slowness "So I went in to the libraries and removed all the links that went to my laptop and skydrive and Bridge worked perfectly as would be expected on a new PC. So check your libraries. This might also explain why some people found that a new account solved the problem."
