I have Laptop with i7 (4 cores), 8GB ram and SSD OCZ Vertex 3 MaxIOPS which in testing that I did just now does 400mb/s+ read/write. However the responsiveness of Windows Explorer is far from being perfect. Opening up Computer, Documents, going into folders is very slow (1-5seconds).
I don't have any viruses or spyware and I have tried changing properties to optimize view for General Items. I tried disabling Search Indexer but it made search in Outlook 2010 crawl and didn't bring any other effect. Even double clicking on file takes some time to open things up (like clicking a Word document).
I don't have any drives mapped, my computer is not joined to domain. I have multiple VPN connections that I connect to but they all have disabled default gateways. I tried using CC Cleaner or some Windows 7 Tweaks app to disable some things.
I am power user using Visual Studio, Tortoise SVN and other developer/administration apps. Any non obvious ideas?
Edit: So I've been trying to pinpoint where the issue comes from and it seems that straight after reboot Windows Explorer opens very fast, when I load 3-4 programs (Royal TS, Visual Studio, Outlook) it's noticeably slower and the more programs I have it gets worse. After I start closing programs it starts working better and if I leave 2 open it's fast again. I tried doing some research with DiskMon and other programs from sysinternals but couldn't find anything suspicious.
Below are stats during normal usage with a lots of programs open:
- Ram usage with a lot of programs open and no swap file (i disabled it for testing): 6.95GB
- CPU usage: 15%, none of the cores takes more then 50% (I have VS 2010 open x 4)

Search indexer or something else (anti-virus scan/update) running and using alot of CPU time/disk access? – HaydnWVN – 2011-11-22T12:32:17.440
CPU usage (5%), memory usage (2.29gb) and hdd is all fine. I can now run SSD Test with HD Tune and it shows 400mb in/out so it's clearly not an issue. I don't have antivirus. – MadBoy – 2011-11-22T12:36:33.500
Any Windows 'System Maintenance' things running? Does the SSD Test run within Windows? – HaydnWVN – 2011-11-22T12:40:07.487
Yes, i use HD Tune with all programs open and running. There's nothing running except backup tool but I disabled it's services for testing and there's no change. It's all the time like that. After reboot too. – MadBoy – 2011-11-22T12:42:01.110
Was this the same setup when Windows 7 was installed? Just thinking something along the lines of pagefile being too small... – HaydnWVN – 2011-11-22T12:43:48.447
1My pagefile is 8gb currently managed by system. From 16mb minimum to 12gb max. 88gb free space on SSD. – MadBoy – 2011-11-22T12:45:48.333
let us continue this discussion in chat
– MadBoy – 2011-11-22T12:46:02.217I'm all outta answers/suggestions i'm afraid! Also can't chat while at work :) – HaydnWVN – 2011-11-22T12:55:55.300
1After reboot it started working fine. Very fast and dandy (so some fixes I applied seems to taken action). However I am now like 10-15 minutes after reboot and it does feel a bit slower then from start. Will see how long it goes like this. – MadBoy – 2011-11-22T13:11:23.703
Goodluck! Biding the time until Xmas and i'll get around to installing my SSD! Until then i don't have the time :/ – HaydnWVN – 2011-11-22T14:11:19.330
It's still bad. After working for a while opening things takes a while.. – MadBoy – 2011-11-22T18:44:37.747

Try the various SysInternals utilities to see what is going on during this slow down. Can start with Process Monitor http://technet.microsoft.com/en-gb/sysinternals/bb896645
– Brian – 2011-11-23T07:11:38.270As a sideline to Sysinternals - check your kernel useage, might be something broken within Windows itself – HaydnWVN – 2011-11-23T11:04:50.190
Right now process Explorer shows explorer.exe with 214 788 225 page faults. While next in line Outlook and setPoint are around 16 730 766. So just 200000 more.. – MadBoy – 2011-11-23T12:17:30.887
Go to oldapps.com, download and install a version 3.6 or lower(older) mozilla firefox and you shall be slow no more. – None – 2011-11-24T16:23:50.393
