Clear Windows Log Files
In this post, we are going to talk about the Windows log files. Windows log files keep a record of various activities of your PC. These include list of errors/exceptions, internet browsing history etc. Even though they don’t create a problem but with time these logs grow bigger in size and thus reducing the amount of free space on your hard disk.
Because I've seen this question asked in many places and not answered, I thought I'd post my issue and resolution here. I regard this as a Bug, but I'm not invested enough to deal with the support incident process.I've had repeated instances where a Windows 7 x64 client runs out of hard drive space, and found that C:WindowsTEMP is being consumed with hundreds of files with names following the pattern 'cabXXXXX', generally 100 MB each, and these files are constantlygenerated until the system runs out of space.
Upon removing the files & rebooting, the files start being generated again.I've found that this is caused by large Component-Based Servicing logs. These are stored at C:WindowsLogsCBS. The current log file is named 'cbs.log'. When 'cbs.log' reaches a certain size, a cleanup process renames the log to 'CbsPersistYYYYMMDDHHMMSS.log'and then attempts to compress it into a.cab file.However, when the cbs.log reaches a size of 2 GB before that cleanup process compresses it, the file is to large to be handled by the makecab.exe utility. The log file is renamed to CbsPersistdatetime.log, but when the makecab process attempts to compressit the process fails (but only after consuming some 100 MB under WindowsTemp). After this, the cleanup process runs repeatedly (approx every 20 minutes in my experience). The process fails every time, and also consumes a new 100 MB in WindowsTemp beforedying.

This is repeated until the system runs out of drive space.This can be reproduced by trying to manually create the cab file -Directory of C:CBS-BAK 02:28 PM. OH MY GOD this is what's been going on.The thing that gets me is that Windows hides the contents of c:windowstemp by default.
