Your Lenovo boots to a blue screen that says "Undoing changes made to your computer" and either sits there for hours or loops back to it after every restart. Here is what is actually happening: a Windows update failed partway through installation, and Windows is rolling itself back to the last working state. Sometimes that rollback finishes on its own. Sometimes it gets stuck in a loop, and on a meaningful share of the machines we see, the loop is a symptom of something bigger: a storage drive that is starting to fail.
The short answer: give it time first, then use Windows recovery to remove the failed update. If the loop keeps coming back after that, stop. Repeated update failures on Lenovo machines are one of the most common early warnings of a failing drive, and continuing to force restarts risks your files.
The rollback is real work: Windows is restoring thousands of system files. On a healthy SSD it usually finishes within 30–60 minutes. On an older machine or a hard drive, it can take two to three hours. Plug the laptop in, leave it alone, and do not power it off during this window. Pulling the power mid-rollback is how a recoverable situation becomes an unbootable one.
If the machine loops back to the same screen after a full rollback cycle, Windows has a built-in recovery environment that loads without needing a working Windows:
That is the one fix worth doing at home, and it resolves the majority of these loops. Everything deeper, registry-level repair, component store repair, or in-place reinstalls, belongs on a bench, because doing those on a drive that is failing can finish the drive off.
When a Lenovo comes through our Somerville shop stuck in this loop, or catching it every few weeks, the pattern behind it is consistent: updates fail when Windows cannot reliably write to storage. Bad sectors on an aging drive, a nearly full SSD with no room for the update staging files, or corrupted system files from a previous unclean shutdown. The update loop is the visible symptom. The drive is often the disease.
That matters because the stakes are your files. A drive that is failing enough to break updates is failing enough to lose data, and every forced restart spins the wheel again. If your machine has looped more than once, or takes noticeably longer to boot than it used to, or you have heard clicking from an older hard drive model, stop restarting it and bring it in. Our $75 diagnostic (credited toward the repair) checks the drive's health directly, and if the drive is on its way out, we get your data off it first, then fix the update problem on storage that can actually hold an update. If files have already become unreachable, that is data recovery territory, and sooner is always better than later.
The repair depends on what the diagnostic finds: on a healthy drive, we clear the stuck update state, repair the component store, and bring Windows fully current, including firmware and BIOS updates that Lenovo machines often need before big Windows updates will take. On a failing drive, we clone your data to a new SSD, install Windows clean, and move your files over, which also leaves the machine faster than it was. Drop-off at our Somerville shop, and most of these are same-day or next-day.

How long should "Undoing changes made to your computer" take on a Lenovo?
Usually 30 to 60 minutes on an SSD, and up to two or three hours on an older hard drive. Keep the laptop plugged in and do not power it off during the rollback. Interrupting it can leave Windows unbootable.
Will I lose my files if my Lenovo is stuck on this screen?
Usually not from the loop itself. The rollback only touches system files. The real risk is the underlying cause: if a failing drive broke the update, that drive is also a threat to your files, which is why repeated loops deserve a drive health check rather than more forced restarts.
Why does my Lenovo keep getting stuck on the same update?
Repeated failure of the same update points to something persistent: bad sectors on the drive, a nearly full disk, corrupted system files, or outdated firmware the update depends on. A one-time failure is bad luck. A repeating one is a symptom worth diagnosing.
Can I just stop Windows from updating to avoid this?
You can pause updates for a few weeks, and that is a fair short-term move. Blocking them permanently trades one problem for a worse one, since security patches stop too. The durable fix is addressing whatever is making updates fail on your machine.
