According to multiple feedback on Microsoft Connect, at least the IE9 RC browser installed on Windows 7 may cause sidebar.exeand svchost.exe Memory leakage.
The actual situation is that the memory usage of sidebar.exeand A svchost.exe will exceed 100 mb in about half a while after the installation.
The original text on Microsoft Connect is as follows:
My normal memory usage for my installation has been at 1300 MB-1500 MB with out launching any other programs that are not launched at startup or login. (yes I know this is kinda high but they are used. things like Live messenger, Live Sync. ect .) today I loged into my pc to see memory usage over 3000 MB and I HADN' t launched a single non auto start program yet. with 4 GB of ram to my system this is quite a problem. I checked task manager to see if I cocould find the offending applications. I found sidebar.exe using around und 1 GB of ram and scvhost.exe using around 500 + MB (there where two scvhost.exe and that was the larger of the two) I closed out the sidebar and got a lot of my ram back but scvhost.exe while it did go down still was around 300 MB.
This kinds of performance I did not see in IE9beta and I have not changed any other programs or habits since the IE9 RC install. the gadgets are the same ones I have been using for a while now without seeing this kind of memory usage before IE9 RC.
I really hope this gets fixed soon!
