AskAdmin allows you to block access to programs and text files.This portable tool can be useful if you have children or if multiple people are using the same computer. Simply drag and drop what you would like blocked into AskAdmin and by default the item is blocked. The blocking is provided by calculating the MD5 hash code of the given file and then it modifies the group policy in order to restrict access to that specific hash value.The basic block functions of AskAdmin are free however if you would like password protection of your blocked items then you need to purchase and register it.
