I have 60GB SSD, and I had like 10GB of free space, before I installed 1.5GBs of updates. Now I have 1GB. So, where are those win update installation files, and any other temp or unneeded trash files?

Thanks in advance.

If you don't use the hibernate mode (suspend to disk) you can disable it. That will delete the hidden file C:\hibernate.sys which has the size of your main memory.

If you don't want to loose the hibernate mode and you have an additional HDD in your system you can create a special hibernate partition on the HDD.

For more details see Creating a hibernation partition on Windows 7

Thanks for the hint. Typo is now corrected. – Robert May 16 '12 at 18:32

run cleanmgr.exe should allow you to clean temporary files etc. in your OS disk.

There's a comprehensive article over at Lifehacker. This solution requires a reinstall though. I don't know if that's something you're willing to do but it could pay major dividends.

I'm a fan of CCleaner. It has good options to cleanup a lot of temp files related to specific programs.
