+==== Removing the hibernation file ====
+If you are on a desktop and you don't use the hibernation, you can gain a few Gb on the ''C:'' partition by removing the hibernation file. See the appropriate [[other:win7config#changing_the_sleep_or_hibernation_mode|tech note]].
+==== Cleaning some hidden Windows temporary files ====
+//Use with **caution**, only if you know what you are doing!// You will need to use the Administrator/adminuser account
+An easy way to determine the space used by the Window directories is to run a Cygwin shell as an administrator and execute:\\ ''du -sh /cygdrive/c/Windows/* | sort -rh''
+=== C:\Windows\Installer directory ===
+The hidden ''C:\Windows\Installer'' directory can easily grow to more than 10 Gb, because Windows uses it for storing files it needs at installation/update/removal time. Unfortunately, some files that could be removed when they are not need anymore (//orphan// files) stay in this directory.
+You can use the [[http://www.homedev.com.au/Free/PatchCleaner|PatchCleaner]] utility to (re)move these orphan files. Rather than removing those files, you should move them to a disk partition other than ''C:\'' (e.g. ''<some_disk>:\Scratch\<your_login>\PatchCleanerMovedInstallerFiles'') and free a few Gb of disk space on ''C:\''.

+=== C:\Windows\Temp and C:\Windows\Logs\CBS ===
+in some cases, the ''C:\Windows\Logs\CBS'' directory may grow to several Gb, due to some log files rotation and compression problem. In that case, remove everything (that you can), except the latest file, ''CBS.log'', and remove what you can in ''C:\Windows\Temp''

 Some programs may install start up services that you don't really need. Disabling these services may free some memory and decrease a bit the CPU usage...
