Hello, I'm using Windows 7 Home Basic x86, 7600.16385.090713-1255 and I experiencing problems navigating through folders in Windows Explorer. Navigation is slow due to the fact that for some unknown reason, a delay before opening the folder. At this moment, to open the folder spent about 5 seconds. After clicking the mouse the busy system cursor icon appears for a few seconds then the folder with all content opens immediately. This is REALLY annoying. And this delay is increasing day by day. When I just installed the system and all of the necessary programs, there there was no delay at all, folders open instantly. After several days, a small delay and a busy cursor appears when opening folders. A few days later, the delay increased to 2 seconds. Then - to 3 etc. Now it is 5 seconds and I think, it will increase more. I tried to reinstall system (both x86 and x64, Home Basic and Home Premium), install debugging tools, manage a power profile, used Autoruns or ShellExView to manipulate shell extensions. Restarting explorer.exe wasnt helpful. I also tried to install just a minimum of needed software (OpenOffice, Kaspersky Internet Security, Firefox, Thunderbird, Miranda, uTorrent) and that wasnt helpful at all too. I tried to disable antivirus - still nothing changed. All of my system drivers are up to date and installed by the OS itself. Under other user's profile there is also the same delay. The only one thing, which helped - after booting in safe mode, the delay was gone . In normal mode the delay still presents. So, I think that some kind of software cause this, but I do not have any ideas what program is causing this delay. I tried really EVERYTHING, what I found in Google for "slow browsing folders", both for Windows 7 and Windows Vista (also, in Windows Vista there was not this problem for me). Cause the delay is increasing after a period of time, that seems to be some kind of caching, etc, but I also tried to disable all of backup, restore, indexing and caching services in "Control Panel -> Administration -> Services", also without any result. My PC configuration is: AMD Athlon 64 x2 6000+ Asus M4N79 Deluxe 4GB DDR2 RAM ATi Radeon HD5870 80Gb+200Gb+1500Gb+2000Gb HDD's etc. Installed software: Firefox 3.5.5 Thunderbird 3.0 b4 Miranda 0.8.10 Skype 4.1 uTorrent 1.8.4 Semagic 22.214.171.124U The KMPlayer 2.9.4 buid 1436 Fraps 2.9.9 Paint.NET 3.5 Ashampoo Burning Studio 6 Free, version 6.76 TopPlan 126.96.36.1998 FineReader 9.0Pro Alcohol 52% Free 1.9.8 build 7612 Download Master 188.8.131.527 ffdshow Foxit Reader 3.0 (1817) Kaspersky Internet Security 2010 184.108.40.2066 OpenOffice 3.1 Nokia PC Suite 220.127.116.11 WinRar 3.80 VirtualBox 3.0.12 I will be very grateful for any assistance because I do not really want to go back to Windows Vista, although I think its a good OS, but Windows 7 in my opinion is really better. Also, sorry for my english, in some phrases I used translator to write this. Thank you very much.
