WISPTIS.EXE: Identifying, Explaining, Removing

WISPTIS stands for "Windows Ink Services Platform Tablet Input Subsystem". This references an outdated MS-internal name from the team that developed it. This definition from (defunct) TabletPCDeveloper.com:

Wisptis.exe (\Windows\System32) This executable runs as a system service that provides pen-data collection for other components of the SDK.

WISPTIS.EXE is spawned as a service to communicate directly with an input device. On a tablet, it interacts with the digitizer; on a laptop / desktop it interacts with the mouse.

The .EXE ends up on your system when you install Journal Viewer (via Windows Update) and Microsoft Office 2003. I’ve seen it spawned when running Adobe Acrobat Reader, both as an add-in to Internet Explorer and natively when opening a .PDF. Hence, it can get spawned a lot. It also has the bad taste to not go away when AR or the IE session is closed.

The program doesn’t cause any damage, but it doesn’t do any good on a non-tablet PC, either. I’ve observed it grabbing 13-20MB of system RAM, but only a few cycles (might be higher in drawing programs). Removing it requires:

  • Stopping the service if it’s running (ensure AR is closed and stop the process in Task Mangler).
  • Modifying the registry (.REG file contents below)
  • Deleting the executable (C:\Windows\System32\WISPTIS.EXE).

As it can come back through various patches, you may have to remove it again.

The registry keys to remove are below (in WinReg .REG format). I’ve tested this on multiple WinXPSP2 systems. It’s a good idea to set a system restore point or to back up these keys to a .REG file before removing them. Once you’re comfortable you’ve not done any system damage, copy and paste the commands below to a .REG file. Note the "-" sign in front of the HKEY is syntax to remove the specified key:

About Michael Coates
I am a pragmatic evangelist. The products, services and solutions I write about fulfill real-world expectations and use cases. I stay up-to-date on real products I use and review, and share my thoughts here. I apply the same lens when designing an architecture, product or when writing papers. I am always looking for ways that technology can create or enhance a business opportunity .. not just technology for technology's sake. My CV says: Seasoned technology executive, leveraging years of experience with enterprise and integration architectural patterns, executed with healthy doses of business acumen and pragmatism. That's me. My web site says: Technology innovations provide a myriad of opportunities for businesses. That said, having the "latest and greatest" for its own sake isn't always a recipe for success. Business successes gained through exploiting innovation relies on analysis of how the new features will enhance your business followed by effective implementation. Goals vary far and wide: streamlining operations, improving customer experience, extending brand, and many more. In all cases, you must identify and collect the metrics you can apply to measure your success. Analysis must be holistic and balanced: business and operational needs must be considered when capitalizing on a new technology asset or opportunity.
