Windows Reinstallation — Belgrade

Windows 10 and 11 Reinstallation — with All Drivers

A computer that has been running the same Windows for 3–4 years collects “gunk” — programs you installed once and never opened again, drivers that piled up during updates, old Microsoft files that were never deleted. That is why the system responds more and more slowly. A reinstallation fixes all of it in 1.5h.

What our reinstallation includes

  • Backup of all your documents, photos, and folders — you lose nothing
  • An original Windows 10 or 11 installation (legal ISO from the Microsoft website)
  • Activation — we use your existing license key that is tied to the motherboard
  • All drivers downloaded directly from the manufacturer’s website (Lenovo, HP, Dell, Asus)
  • Microsoft Office 365 or LibreOffice (your choice)
  • Antivirus — Bitdefender Free or Microsoft Defender with a Malwarebytes scan
  • Chrome or Firefox + essential programs (VLC, 7-Zip, PDF Reader)
  • A test of every component — checking that Wi-Fi, Bluetooth, camera, microphone, and sound all work

When a reinstallation is NOT needed

Some systems look slow, but the problem is something else. You do not need a reinstallation if:

  • You see a blue screen (BSOD) — that is usually RAM or the disk, not the software
  • The laptop overheats — that is thermal paste, not the system
  • The disk is full — that just needs excess files deleted or a new disk
  • A specific program does not work — usually just reinstalling that program is enough

We run a diagnostic, see what the issue really is, and then advise you. We never recommend a reinstallation if it is not needed.

Service prices — in the official price list

All service prices (diagnostics, repairs, cleaning, reinstallation…) are on our price list page and are always up to date. We confirm the final price after a free diagnostic, before the repair. A courier picks up and returns the device, or you bring it to one of our locations.

Questions

Will I lose my documents and photos?

No. Before we start, we back up everything in the Documents, Pictures, Desktop, and Downloads folders. After the reinstallation, we restore it. If you have files in other locations (e.g., the D: drive, an external drive), just let us know and we will save those too.

Do I need a licensed Windows, or do you use “some” version?

We use an original Microsoft ISO image. If your laptop has a Windows 10 or 11 license (most purchased laptops do — it is stored in the BIOS and the system activates itself), we use it. If not, we can sell you a new key (the exact price is in the price list). We do not install pirated software.

Does a reinstallation speed up an old laptop too?

Dramatically — if the problem was software-related. But be careful: if the laptop has an HDD, the biggest jump comes from adding an SSD (along with the reinstallation). Without an SSD, a clean Windows will boot in 30 seconds instead of 2 minutes, which is enough for most users.

How old a laptop can “survive” a reinstallation?

A reinstallation does not wear out the hardware. If the laptop is physically sound (RAM OK, disk OK, battery optional), the system will run for years. We have clients using a Lenovo from 2012 with a reinstalled Windows 10 who say it works perfectly for email and Office.

Frequently asked questions

How long does a Windows reinstall take?
In most cases it is done the same day or the next one, depending on how fast the drive is and how many drivers and programs have to go back on. If the machine has an SSD, the whole job is considerably faster than on an old hard disk. We call you as soon as it is ready for pickup.
Will I lose my data when Windows is reinstalled?
You do not have to. Before every reinstall we back up your files (desktop, documents, pictures, Downloads) and put them back afterwards. If you actually want a clean install without any of the old data, tell us and we will do it that way, but the standard is that you lose nothing.
Do you install the drivers and the basic programs as well?
Yes. After a clean Windows install we put on all the drivers (network, graphics, sound, card reader) and the basic programs: browser, PDF reader, archiver. You get the machine ready to work on, not a bare system that cannot even get online.
How much does a Windows reinstall cost?
Diagnostics are free, and we give you the exact price after we look at the machine, because it depends on whether you need only the reinstall or a backup, drivers and a cleanup as well. Ballpark prices are in our price list. We do not start the job until you confirm the price.
How do I get my computer to you for a reinstall?
If you are a private customer, a courier can pick the machine up at your address and bring it back when it is finished, or you can drop it off at one of our three shops in Belgrade (Arena, Piramida, Centar). We give a warranty on the work we do.
