It's important to recognize that not everything submitted will be added to the archive. Some things are so common (e.g. Windows 95 ISOs) that they aren't worth including. The archive is meant to be a collection of uncommon media related to Microsoft. However, we also realize even that explanation has some uncertainty to it. We've provided a table below outlining the things we recommend and don't recommend submitting.
| Media Type | Accepted | Notes | Example(s) |
| Retail versions of unsupported products without a supported equivalent | Yes | Windows Live Essentials 2009 | |
| Beta versions of unsupported products | Yes | ||
| Developer media (MSDN, SDK, etc) | Yes | Xbox SDK | |
| Digital (downloadable) applications, games and operating systems | Yes | ||
| Digital Microsoft MSDN, Technet and VLSC software | Yes | ||
| Original photo, artwork and clipart collection media | Yes | ||
| Original font collection media | Yes | ||
| Original press kit and promotional media | Yes | ||
| Original demo/trial/evaluation software | Yes* | This may depends on what you're submitting. | |
| Magazines and book media | Yes* | Please only submit related pages and not the whole book (unless the book is Microsoft-related as a whole). | |
| Retail versions of unsupported products with supported equivalents | Probably* | This depends on how recent the product is. | The DirectX 2.0a installer is more likely to be accepted than the DirectX 11 installer, since it's harder to find. |
| OEM OS media | Unlikely | That OEM OS media better have something rare on there, cause i'm not hosting 2.5 TB of Dell touchpad drivers. | Gateway Windows Vista Express Installation ISO |
| Harddrive or partition dumps | Unlikely | You should probably dump any rare software included on it's own instead of the whole drive. | |
| Commomly archived software | No | A general rule of thumb for determining whether something is too common to bother archiving is whether or not you can find multiple archive.org links on the first page of Google. | Pretty much any Windows ISO, Office 2007, etc. |
| Any third party copies of original media | No | This is the Unofficial Microsoft Archive, not the Unofficial DiLshad Sys Archive | Windows 9 Pro by DiLshad Sys |
| Source code of any kind | No | Absolutely not | Leaked Windows NT 4.0 source code |
| Retail versions of currently supported products | No | Windows 11, Office 365, Copilot | |
| Beta versions of currently supported products | No | Windows 11 betas | |
| Invalid or improper dumps | No | ||
| Pre-installed virtual machines | No |
