What to do first
Check the Microsoft account, cancel only the stuck download, run wsreset, verify storage and Windows Update, then retry one app at a time.
Windows apps
A Store download that stays pending can be waiting on another update, a sign-in token, storage, cache data, or a connection problem.
Quick answer
Check the Microsoft account, cancel only the stuck download, run wsreset, verify storage and Windows Update, then retry one app at a time.
Why it happens
Store downloads share Windows update and delivery components. A queued update or damaged cache can block every app behind it.
Step by step
Safety note
Protect important files before resets, driver removal, account changes, or recovery operations. If the symptom points to hardware, repeated software changes can make diagnosis harder.
Another update, account authentication, Store cache, low storage, or Windows Update services may be blocking the queue.
Canceling a pending download normally removes the queued install attempt; you can start it again after fixing the underlying issue.
