**Progressbar NOT** 4.0 (Progressstation) is the ninth release of Progressbar and the second and the last system to have the Custom game mode in the Progress Computer lineup. It resembles Windows NT 4.0, released on 31 July, 1996.

This system is similar in design to Progressbar 95, except for some changes:

* A unique logon screen has been introduced;
* ProgressDOS is renamed to Progress CMD and ScanProgress is renamed to CHKPROGRESS, since the system uses the NOT kernel;
* Firewall and Mailbox are added;
* Browser is removed;
* There are unique wallpapers.

To unlock Progressbar NOT 4.0, the player has to have at least one Expert badge.

## Trivia

* This is the first Progressbar by release in-game where the game mode can be customisable.
* This is the first overall Progressbar system by release in-game that requires a password to log into the system. The second was Progressbar NOT 3.60.
* This is the earliest version of Progressbar that has Progress CMD instead of ProgressDOS and CHKPROGRESS instead of ScanProgress.
* In both versions of *Progressbar95*, it is possible to get this operating system second without going to the Store. All the player needs to do is to get an Expert label on Progressbar 95.
* Although this system uses blue for the colors of blue segments, the graph after completing a level still has teal for the blue part from Progressbar XB. This is due to Progressbar NOT 4.0 being based on Progressbar XB.
* This is the second and last Progressbar NOT system to not have Browser. The first one is Progressbar NOT 3.60.
* This is the second earliest version (after Progressbar NOT 3.60) that has the User option in Settings.
* This system has a different Shutdown Complete screen than the others (alongside the BarOS lineup of systems), since it is in a window. The Turn On button now appears immediately instead of being delayed.
	+ This is because Classic Mac OS and Windows NT 4.0 have a different safe to shutdown screen.
* This is the only Progressbar NOT system that is missing in the first-era Progressbar website's Products page in Browser.
* The word "Progressstation" is missing from the banner in the begin menu, possibly because Progressbar NOT 4.0 Server, the server counterpart, uses the same assets as NOT 4.0.
* This is the second system to not have startup and shutdown sounds made through a music sequencing program, but rather BeepBox through a recording.
	+ Progressbar Chitown sounds, Progressbar 11 sounds, the BarOS BSOD sound and the unused Error2 sound were also produced through BeepBox.
	+ The two instruments used are "soundtrack" and "voice synth". More instruments in the sounds are unknown.
* The modem shown in the second wallpaper can actually be found on the Internet. Its origin is most likely Ukrainian, since it is seen on the Ukrainian version of the OLX site.
* Clippy wears glasses in this system.
