Registry too has permissions:
As strange as it might sound, Registry too has permissions. You can create a new key and more keys and name-value pairs in the registry to your benefit. Although it is not the best place to hide secrets, there are no limits to innovations! Remember though that you should not use this feature to alter permissions on any key you like. It may cost you a complete system reinstall! But you can surely keep treasured some of your little nifty secrets somewhere deep down the registry and lock it so that others do not discover it. To use this feature, simply right click a key and select ‘permissions…’.

Disable Compression on your system:

Although NTFS serves with two great and useful features of Encryption and Compression on your system, they have their own hitches. Compression needs time. Whenever you open a compressed file, decompression has to be done. When you make changes to such a file, the contents or the changes are to be compressed again. In some situations (such as a video editing environment), this has to be avoided at all costs.

You can ask Windows to disable NTFS compression feature. For this, you need to open the registry editor (type regedit on the start search, hit Enter and say ‘yes’ to UAC prompt) and navigate to the following location on the left pane: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFileSystem. On the right pane find the key named ‘NtfsDisableCompression’. Now, double click it to edit the value and enter ‘1’ (without quotes) in the value data field.

Upon restart, your machine will no more have the forte to compress files. Not to worry though. The files which are already compressed will continue to behave normal but no new files will be fortunate enough to be compressed anymore. Even those which were compressed before cannot be decompressed and compressed back again. If you try, you get an error message.
