If our system cannot cope with the .USERPROFILE extension and failed all the automatic and semi-automatic methods of teaching it this art, manual editing of the Windows registry remains. This registry stores all the information related to the operation of our operating system, including the connection of file extensions with programs for their maintenance. Team REGEDIT inscribed in the window „search for programs and files” or "run in the case of older versions of the operating system, gives us access to the registry of our operating system. All operations carried out in the registry (even not very complex ones regarding the .USERPROFILE file extension) have a significant impact on the operation of our system, therefore, before making any modifications, you should make sure that you have made a copy of the current registry. The section we are interested in is the key HKEY_CLASSES_ROOT. Next instruction shows, step by step, how to modify the registry, and specifically the registry entry containing information about the .USERPROFILE file.

Step by step

• Press the “start” button
• In the "find programs and files" window (in older versions of Windows it is the "Run" window) enter the "regedit" command and then confirm the operation with the "ENTER" key. This operation will launch the system registry editor. This tool will allow not only to view existing records, but also to modify, add or delete them manually. Due to the fact that the registry of the Windows system is key to its operation, all operations carried out on it should be performed judiciously and consciously. Careless removal or modification of an inappropriate key can permanently damage the operating system.
• Using the ctr+F key combination or the Edit menu and the "Find" option, find the .USERPROFILE extension you are interested in by typing it in the search engine window. Confirm by pressing OK or using the ENTER key.
• Backup copy. It is extremely important to back up the registry before making any changes to it. Each change has an impact on the operation of our computer. IN extreme cases an erroneous modification of the registry can make it impossible to restart the system.
• The value you are interested in regarding the extension can be manually edited by changing the keys assigned to the found extension.USERPROFILE. Here you can also create your own desired entry with the extension a.USERPROFILE if this is not in the registry. All available options are in the manual menu ( right button mouse) or in the "Edit" menu after placing the cursor in the appropriate place on the screen.
• When finished editing the entry for the .USERPROFILE extension, close system registry. The introduced changes will come into effect after restarting the operating system.

Due to the fact that in the operating room family Windows systems folders with temporary files for some reason are not cleared by themselves, they can accumulate a huge variety of different junk files, reaching a total size of up to several gigabytes! Various viruses and bad scripts periodically hide among temporary files, so it is the duty of every PC user to regularly delete the contents of temporary folders.
