There is a particular glitch in Windows 7 I really dislike. I boot up my machine.. .it takes a long time saying preparing desktop. then it boots in a completely new desktop saying "You have been logged on to a temporary profile". I shutdown and start again, and this time it logs me back on my usual desktop. This is so stupid and such a waste of time... does anyone understand why windows 7 does something like this? What the point of creating a new temporary profile for the user just out of the blue .. and then switch back to the usual one on next reboot?

There are problems in your user profile. It seems that some programs or device drivers cannot start to work at the first logon. Did the issue started to occur recently? If so, use System Restore.Arthur Xie - MSFT

I have three windows 7 machines. My office laptop, my home laptop and my workstation and this issue comes on all 3 of the machines intermittently. so are we saying that the profiles are problematic on all the 3 machines .... hummmmm....... This problem has always been there on Windows 7 . (I am using Windows 7 since it was beta). it only occurs occasionally. and gets resolved in one or two reboots.

You may have contracted a virus. You can download offline virus scanners and root kit detectors to check you systems. Your symptoms are definitely not normal behaviour for Windows 7, or any other version of Windows. There has to be something you have done to cause this. I have been running Windows for well over 15 years and I have never encountered this type of behaviour on regular installations.

Maybe: 1. You have installed incompatible antivirus on all computers. 2. You have used third party Registry cleaner or system optimizing tools. These tools may corrupt the Registry. 3. You have same Startup programs on all computers and one of them may be the root cause.Arthur Xie - MSFT

If find the virus theory very hard to believe because all my office laptop has macafee and my home workstation and laptop have norton 360. I run periodic checks so far nothing has been reported. No 3rd party registry cleans. Also you need to remember that a simple reboot solves the issue temporarily and then for a few days/weeks (depends) this problem will not come... then once in a while it will return. If my registry had gone bad or there was a virus, the problem would be more frequent. The startup programs on 3 computers are not the same, because office laptop is running on official policies and home laptop has stuff like picassa, Gtalk, Skype. I have been a windows 7 beta user (and then this problem used to occur much more frequently). I have formatted the drive and installed a clean Win 7 Ultimate on my workstation and Win 7 home on my laptop. The office laptop uses Win 7 Pro (or enterprise) or something like that.... but is also a clean install.

If this has been happening since the Beta was released then you need to look at your hardware for problems. If you are not going to listen to anyone then don't waste your time posting here. Whatever your problems are they are specific to your environment and they are not Windows 7 fault! You need to look very closely at your hardware and the software you are installing!

I don't want to make you angry further ... but ... i find it hard to believe the theory that all 3 machines are having hardware problems :)

What I have a hard time comprehending is why you are so convinced that Windows 7 is the problem? Whether you like the truth or not, Windows 7 is not the problem and you need to do some serious evaluation of the entire environment to find out what is causing your problems. If Windows 7 is the problem then literally hundreds of thousands of people around the world would be having exactly the same symptoms you are having - but, there are not!
