Good idea, and you probably are.
Reason I asked about oddities you were experiencing is because I had some on my W7 64bit after updates. Screen icons would flash on and off and occasionally would freeze but, taskbar icons would still work. Mike recommended a reg. scan with Ccleaner and delete what it finds. Did that and so far problems have not reappeared.
I 'think' I found the ROOT problem!!!!
Remember I said "No I decided to look at Windows Update. Wife's machine had gotten the last set, mine did NOT? Tried to check and it said it couldn't, kept running for a long time and then failed. Re-booted, same thing?"? Messing with Malware programs and such it eventually worked?
Well, today I noticed I had a LARGE CBS.LOG file in C:\Windows\Logs\CBS. Much to my surprise I found a TON of 'info' entries during boot.

Found the Troubleshooter for Windows Update and it found a few problems, I didn't keep the list, but it fixed 3 items.

==================
Almost 1 minute? Not significant, but it shows I had a problem. Note the prior boot above too? However that is NOT in the log? Odd? Was in the first part posted above?
I suspect all this was related, I just don't know how?
Discovered yet another problem I 'had'. McAfee screws up ThunderBird if it is allows to filter incoming e-mail. Almost always makes it appear to not be responding. Looks like a McAfee install/update turned that feature on for me. Can cause high spikes in CPU usage and hence, the slowdown, even on a recent i7 Intel CPU (i7-4770 3.4Ghz) with an SSD for the OS no less.
Maybe NOW everything is cleared out and fixed?
