About the increased resource consumption, I kinda hate Microsoft for this one... If the SP1 is just a cumulative of Windows 7 updates, it's not normal to eat up the HDD space almost 2 GB and almost 500 MB of RAM. kinda weird... What should I do to free up HDD space? all useless features and program I installed already removed. But the suspect is still the WINSXS folder.
One more thing (sorry if I asking too much), since last year... I wanna know is there any tutorial to move the WINSXS folder to another partition.. some references is using a junction point but I couldn't understand what and how to make a junction point. I kinda hate this WINSXS folder, It's very huge and easily increasing everyday.
This is getting a bit out of my knowledge range.
From what I think I understand, the SP1 included a lot more than just a cumulative of previous updates. I might be wrong but I think I read it also included several hundred additional updates. As to the SXS (side by side) assembly, this is Microsoft's way of reducing DLL (dynamic link library) problems. Used to be computers would have problems when there were missing, or duplicate DLLs. In SXS, Windows stores multiple versions of a DLL in the WinSXS subdirectory of the Windows directory, and loads them on demand. This reduces dependency problems for applications that include an SXS manifest. In other words, the SXS folder can get very large very quickly.
How to make this better? Short of getting a larger HDD for your netbook or using a large external HDD (which absolutely defeats the purpose of having a small, easily transportable machine) I'm not sure what can be done. As long as your machine has at least 15-20% free space on the HDD and as long as you're not exceeding available RAM, a lot of people would say, "What's the problem? That's what the HDD and RAM are for ... to be used."
Let us know how that tool works out. And I'm sorry i couldn't be more help. Perhaps someone else will see this thread and jump in with better information.
