Supported Desktop Operating Systems

The table below summarizes what SAS Computing currently recommends and supports for operating systems. More details regarding some of the issues involved follow. Please also see the information regarding SAS Computing Hardware Support and Desktop Computer Purchasing.

In general, SAS Computing seeks to support the same products that are recommended by ISC.  However, especially where operating systems are concerned, SAS Computing sometimes makes recommendations and decisions regarding support that may differ from those of ISC. Please be aware that these choices are driven both by technical considerations and by the limitations of our staffing levels. We are simply not in a position to be able to support all new operating systems soon after they are released. There are also times when the minimal advantages of a new release simply do not justify expending significant staff time to provide full support, when this time could be better spent on other higher priority support activities.

Explanation of Support Status terms:

  • Full - the standard support for all recommended platforms. SASC staff will have expertise for these platforms and will not limit support for them.
  • Minimal - only minimal efforts will be expended by SAS Computing staff to support this product, and we make no claims to expertise in doing so. If significant effort is required to solve a problem due to the use of the non-recommended product, SASC will generally recommend that the user move to a supported platform or seek support elsewhere. Security configuration of the machine will generally be the user's responsibility, and any initial configuration may be as well.
  • Upgrade - work with SAS Computing LSP to upgrade the OS on this machine. 
  • None - SAS Computing staff will not expend efforts to support this (typically long obsolete or very new) product.

Specific Issues:


  • Not recommended because unlikely to be adopted by large percentage of those supported by SASC
  • Some support is provided by some LSP's
