Windows 11 26H2 Slow After Update Remove Bloatware Speed Up Your PC

Every big Windows update quietly installs apps you never asked for — games, trial software, shopping apps. They eat RAM, run in the background, and make a good PC feel old. Here is the safe way to remove them.

✍️ Technical Anshu🪟 Windows 11 26H2⏱️ 15 minute fix
🎥 Watch the full debloat process in the video — every option explained, step by step

Windows 11 version 26H2 is here, and like every feature update before it, it arrives with a fresh load of bloatware — pre-installed apps that sit in your Start menu, start with Windows, and use memory for no reason. The good news: almost all of it can be removed safely in one session. We will use the free, open-source Win11Debloat script by Raphire — the same tool shown in the video — but first, one safety step that most people skip and later regret.

Task Manager — Performance
CPU34%
Memory6.9 / 8.0 GB
Disk (HDD)100%
GPU12%

What a loaded Windows 11 PC looks like before cleanup: memory nearly full and the hard disk pinned at 100% even for small tasks.

1

Create a Restore Point Before Touching Anything

A debloat script removes apps in bulk. If you remove something you actually needed, a restore point is your one-click way back. This takes two minutes and saves hours.

  1. Press Windows + R, type sysdm.cpl and press Enter
  2. Open the System Protection tab and select your C: drive
  3. Click Create, name it "Before Debloat" and wait for it to finish
  4. If protection is Off for the drive, click Configure and turn it on first

Remove the Obvious Junk Manually First

Settings — Apps — Installed apps
Candy Crush Saga412 MB
Spotify Music268 MB
Disney+196 MB
TikTok154 MB
Booking.com118 MB

Typical pre-installed apps that arrive with a new PC — most owners never open them once.

Before running any script, clear the easy wins yourself. You will be surprised how much of the "slow" feeling is just this list.

  1. Open Settings → Apps → Installed apps
  2. Uninstall the pre-installed games, trial antiviruses, shopping and streaming apps you never opened
  3. Check Settings → Apps → Startup and turn off apps that do not need to launch with Windows
  4. Restart once and note how the PC feels — this is your baseline before the script

Run the Win11Debloat Script (As Shown in the Video)

Win11Debloat is a free PowerShell script from GitHub (github.com/raphire/win11debloat) that removes the bundled apps Microsoft's own uninstall button hides, and can also turn off things like Copilot suggestions and telemetry-heavy extras. Run it exactly like this:

  1. Right-click the Start button → Terminal (Admin) or Windows PowerShell (Admin)
  2. Paste this command exactly and press Enter:
    & ([scriptblock]::Create((irm "https://debloat.raphi.re/")))
  3. The script window opens with a list — choose the Default mode if you are unsure, or Custom mode to pick item by item
  4. Read each item before confirming. If you use Xbox Game Bar, Widgets or OneDrive daily, leave those in place
  5. Let it finish, then restart the PC — many changes only apply after a reboot

Clean Up What the Script Leaves Behind

Settings — System — Storage
Local Disk (C:)168 / 180 GB
Installed apps54 GB
Temporary files9.2 GB
Documents38 GB

Even after debloating, a nearly full system drive needs the storage cleanup shown in this fix.

After the restart, do a final five-minute pass so the cleanup actually translates into speed.

  1. Open Task Manager (Ctrl + Shift + Esc) → Startup apps tab and disable anything left that you do not need at boot
  2. Open Settings → Apps → Installed apps once more and remove leftovers
  3. Run Settings → System → Storage and clear Temporary files if your C: drive is nearly full — a stuffed system drive slows everything down

Watch the Video Before You Run It ⭐

One honest warning from experience: a debloat script is powerful, and pressing "remove all" without reading can delete apps you actually use — and a few removals (like the Microsoft Store) are annoying to bring back. In the full video, every screen of the script is shown and each option is explained in simple words before anything is removed. Watch it once, then run the script alongside — that is the safest way to do this.

🔴 Honest expectations: Debloating makes Windows cleaner and lighter, and on a low-RAM PC the difference is clearly visible. But no script can turn an old hard disk or 4 GB of RAM into new hardware. If your PC is still slow after this guide, the problem is somewhere else — check the 100% disk, startup and SSD cases on this page's channel for the next step.

❓ Common Questions (FAQ)

Is the Win11Debloat script safe to use?

It is a well-known open-source script, which means anyone can read exactly what it does before running it. Still, treat it with respect: create the restore point from Step 1, read every item in Custom mode if you are unsure, and never run debloat commands copied from random websites — use only the official project link shown in the video.

Will the bloatware come back with the next update?

Sometimes, yes — feature updates can reinstall some bundled apps. The fix is simple: keep this guide bookmarked and re-run the same steps after a major update. It takes ten minutes once you have done it the first time.

My PC is still slow after debloating. What now?

Then bloatware was not your main problem. Check Task Manager while the PC feels slow: if Disk shows 100%, work on that first; if Memory is near full, it is a RAM/startup issue; and if your Windows is installed on an old hard disk, an SSD upgrade will beat every software trick combined.
