To clear the DirectX shader cache on Windows 10 or 11, close your games, open Disk Cleanup for your Windows drive, select only DirectX Shader Cache, and confirm Delete Files. Windows will create cached shader data again as applications need it. This removes a cache, not installed games, but the first launch afterward may spend time rebuilding shaders.
Clear the Windows cache with Disk Cleanup
Start here when the goal is specifically to remove the DirectX shader cache. It is a named cleanup category, so you do not need to hunt through AppData or guess which graphics files are disposable.
- Save your work, exit games and other graphics-heavy applications, and let any active game or graphics-driver update finish.
- Open Start, type
Disk Cleanup, and launch the Windows app with that name. - If asked to select a drive, choose the drive containing Windows, usually
C:. Wait for the scan to finish. - In Files to delete, find
DirectX Shader Cache. Check that box. Review every other checked box and clear any you did not intend to clean. - Select OK, then confirm Delete Files. Let Disk Cleanup finish before reopening a game.
The choice at step 4 matters. Disk Cleanup can offer Downloads, Recycle Bin contents, previous Windows installations, and other categories with very different consequences. Selecting only DirectX Shader Cache keeps this operation focused. Once deleted, the old cached copies cannot be restored through Disk Cleanup; the practical recovery is to let Windows and games compile them again. If a game was open, close it and retry the cleanup rather than forcing deletion of files in use.
Write down the free space shown in File Explorer > This PC before and after the operation if storage is your concern. There is no promised amount of space to recover: the displayed category may be small, and other software can write to the drive while you measure.
Use Storage settings as another Windows route
On many Windows installations, the same category is available through Start > Settings > System > Storage > Temporary files. Wait for Windows to calculate the list, then look for DirectX Shader Cache. Select that category, review the other selected categories, and choose Remove files. Microsoft describes the Storage settings path for Windows 10 and 11.
If the category is absent or shows little data, do not assume a hidden directory needs manual deletion. The cache may already be small, or Windows may have nothing eligible to show at that moment. Disk Cleanup is a useful second check, but repeating both tools will not create more removable data.
Avoid selecting Downloads merely because it appears next to temporary files. Those are your own files. Likewise, deleting a previous Windows installation can remove a rollback option. The review screen is your chance to leave unrelated categories untouched; after Remove files, those selected items do not have a general undo button. Restore personal files from your backup if you selected them by mistake.
What clearing the cache changes
Shader caches store compiled results so an application does not have to do the same work from scratch every time. Clearing one can be reasonable when you are investigating a suspected corrupted cache or need the space shown by the cleanup tool. It is not a general fix for every graphics crash, and it will not remove a game installation or change a graphics setting.
The next launch may take longer or show temporary stutter while shaders are built again. The cache can grow after you play, so a smaller free-space number later is not proof that cleanup failed. If a game offers its own shader compilation screen, allow that process to finish before judging the result. Do not clear the cache immediately again simply because it returned.
For troubleshooting, record the exact game, error, and driver version first. Perform this one cleanup, restart the game, and compare the same action. If the problem persists, keep the new result and use the game's or GPU vendor's support steps rather than deleting unrelated Windows folders. Clearing a cache does not repair damaged game files, an incompatible driver, or a full drive by itself.
Separate Windows, driver, and game caches
The DirectX Shader Cache checkbox is a Windows cleanup target. GPU drivers and games can keep other shader data. One checkbox should not be described as a universal reset of every shader cache on the computer. This distinction matters when you compare folder sizes after cleaning or try to solve a particular game's issue.
If you use AMD Software: Adrenalin Edition and specifically need to reset its driver cache, open AMD Software, go to Gaming > Graphics, and look for Reset Shader Cache. Use its reset control if it is present in your version, then allow applications to rebuild the data. AMD's graphics settings guide says this control deletes stored shader cache files. The control may be unavailable in some installations; do not use Factory Reset as a substitute, because that changes a much wider set of settings. The reset has no undo for the old compiled files.
NVIDIA Control Panel offers a Shader Cache Size setting under Manage 3D settings. NVIDIA explains that this limits how much disk space its driver may use and that setting the limit too low may cause more shader recompilation and stutter. A size limit is a policy for future cache use, not the Windows DirectX cleanup button. See NVIDIA's setting reference before changing it. If you change the limit and dislike the result, return to the previous value or the driver default.
Some games and launchers manage yet another cache. Follow their own settings or support instructions rather than deleting a folder just because its name contains shader. For example, Steam's download cache handles downloads; the Steam download-cache guide explains that separate operation. Neither button is a request to remove the game library.
When clearing shaders will not solve a full C drive
Look at the measured size of DirectX Shader Cache before making it your main storage plan. If Windows reports little removable data but C: is nearly full, inspect broader categories in Settings > System > Storage. Installed games, application data, and development caches need decisions about their own contents. The C-drive growth guide shows how to compare what returns after a cleanup.
Do not disable shader caching just to keep a small category empty. A cache is meant to come back, and recompilation can cost time when a game starts. If the category repeatedly becomes unusually large on your machine, note when it grows and which games or driver updates preceded it. That observation is more useful than a scheduled blind deletion.
Reviewing shader caches with AiCleanDisk Pro
AiCleanDisk Pro includes DirectX, NVIDIA, and AMD shader-cache items in its auto-clean list. The app shows a risk level for each item and asks for confirmation before cleaning, so review the exact cache selected. System-drive scanning and auto clean, except AI auto-clean, are free; scanning other drives, AI analysis, AI auto-clean, and moving folders require a license. Its free smart clean covers only low-risk caches, temporary files, and logs, and lets you untick items before cleaning.
Check the result once
After cleaning, launch the affected game once and give it time to rebuild any required shaders. Compare the original error or storage measurement with the new result. If the cache reappears but the game works, that is expected behavior; keep investigating only if the original problem remains.
