Sometimes you can get in situation that Windows Update is not working and you are receiving error
“Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer”.
It can be caused by corrupted data for Windows update. If this is your case fix could be easy.
Windows update serviceC:\Windows\SoftwareDistribution\ folder and delete all its contentWindows update serviceIf you have plenty of RAM and do no want Firefox to save temporary files to disk (for example because you have SSD and want to limit number of disk writes) you can move Firefox cache to RAM.
There is no way how to do it in gui, so you need to use favorite about:config. Search for parameter browser.cache.disk.enable and set that to false. Now disk cache is disabled. Then search for browser.cache.memory.enable and set that as true – it will enable cache in RAM (it is set to true already sometimes).
If you want to set how much RAM you will dedicate to cache, search for browser.cache.memory.capacity and as value set desired cache size in kilobytes.
Moving cache to RAM is good idea only if you have quick internet connection as cache is wiped out on every restart and all pictures, scripts etc. are downloaded again after restart.
